The rational application of green materials is a necessary step for the
development of environment-friendly industries and a circular economy.
However, the popularity and practicality of the sustainable development of
office furniture companies in China still lags far behind the world’s leading
companies. To gain a deeper understanding of the application of green
materials in the Chinese office furniture industry, a questionnaire survey
for enterprises in response to relevant issues was conducted based on an
extensive review of the relevant literature. The research comprehensively
analyzed the application status of green materials in Chinese and
overseas office furniture companies, and the environment-friendly
materials selection strategy of the main materials, and packaging
materials for office desk furniture was proposed according to the current
situation. The results showed that China has vigorously begun guiding and
supporting the green development of furniture manufacturing enterprises,
but there is imperative need of a range of upgrades in the enacting or
revising of laws and regulations pertaining to green manufacturing and
manufacturing technology. Furniture enterprises should seize the
opportunity to promote the application of clean energy and improve the
recycling mechanism of waste furniture with an aim to maximize the
benefits of sustainable development.

INTRODUCTION
Faced with the deteriorating ecological environment, national and international
authorities have been continuously promulgating environmental strategies. China has
established that green and low-carbon development is necessary for enterprise
development, which is related to the quality of high-quality economic development, the
nature of ecological environment conservation, and the most inclusive people’s livelihood
(Tang 2019). The development of the green furniture industry has become an inevitable
trend, and green furniture manufacturing has become an important direction for the future
reform of China’s furniture industry (Xiong et al. 2017). However, in terms of the current
operating conditions of China’s office furniture companies, the penetration of the concept
of sustainable development is not comprehensive enough, and there is a lack of a complete
green manufacturing technology system for the furniture industry (Xiong et al. 2020). As
the material basis of the system, green materials are a key step to achieve sustainable
development. This paper starts from the perspective of green materials and discusses its
application path for office desk furniture. The aim is to provide ideas for the improvement
of the green manufacturing technology system of the furniture industry.

The concept of green material was first introduced at the first International
Conference on Materials in 1988. Green material was designated as an environmental-
friendly material with basic performance characteristics that will not have a negative
impact on the environment after it has been manufactured, utilized, and discarded (Wang
et al. 2019; Xiao 2021). In the category of furniture, green materials can generally be
divided into four categories: natural materials, recycled materials, low environmental load
materials, and environmentally functional materials (Zhu and Wu 2013). With the passage
of time and technological progress, the materials that are used in desks have gradually
expanded from a single natural material. Many materials can be used in desks, such as
wood, metal, plastic, and leather. This is because the need for desk function gradually
increases, causing more materials to be needed to support the function. Such functions of
an office desk may include a lifting system for adjusting office posture, a screen for
protecting privacy, and the cable management of the desk for organizing the desktop
computer (Fig.1). But it is undeniable that wood is still the main material of desk furniture,
and the environmental research on wood materials is still the focus of the future (Wu 2021).

desk, and c) cable management of the desk. (Picture source: https://www.lamex.com/zh-
hans/product/duplex)
In recent years, most Chinese office furniture companies have begun to pay
attention to the application of green materials, especially among high-end brands such as
Aurora Furniture, Sunon, and Onlead. Green materials that are used in the whole line of
products can basically contain minimum or no harmful chemical components, and the
utilization rate of degradable materials is high. Medium and low-end brands may be limited
by capital, do not have a complete furniture processing and production chain, and cannot
strictly control the product supply chain. The materials that are used in medium and low-
end brands are not highly degradable and the degree of environmental performance is
relatively low. Overall, there is still a big gap between Chinese and overseas leading office
furniture enterprises in aspects of the popularity and practical operation of the green
concept.
The penetration and implementation of the concept of sustainable development for
world leading office furniture enterprises are generally high in companies such as Herman
Miller, Steel Case, and Haworth. The materials used in these products have basically
passed the authoritative certification such as GREENGUARD and ISO 14001. In addition
to the material itself, the processing equipment, the energy supply, the product service life,
and the product recycling have been systematically planned. This also benefits from the
guidance of national policies. The furniture industry in the worlds mainstream countries
has high standards for the selection of environmental-friendly materials. One of the main
reasons is the early and high degree of implementation of relevant regulations regarding

green development (Huang et al. 2017). In the late 1960s, the book “Design for the Real
World by American design theorist Victor Babanak put forward the concept of green
development and promoted the transformation of the concept of industry development
(Leng and Teng 2013). A series of environmental rules and regulations, such as the basic
law on countermeasures against public hazards implemented in Japan in the 1970’s, are
already preparing for green development (Liu and Sun 2016). In 2009, the United States
and the United Kingdom repeatedly stressed that the development of a green economy
should be a priority (Li and Li 2011). Therefore, with the investment and support of the
government, the transformation speed of enterprises has greatly improved.
Literature Review
The focus here is on environmental-friendly desk furniture in design and
manufacturing, normal use, and waste recycling. The aim is to improve the greening of
desk materials in line with the scope of enterprise development benefits. In fact, back in
2013, relevant studies showed that most consumers were willing to buy goods produced by
materials and technologies with a low negative impact on the natural environment and are
willing to bear more costs (Shabani et al. 2013). This has had a positive impact on the green
transformation of enterprises. In the process of enterprise operation, customers willingness
to tolerate a somewhat higher prices of green products can directly reduce waste and
environmental costs in their business, while maximizing returns. Customer collaboration
combined with internal green supply chain management is considered as the most effective
way to improve economic performance (Azevedo et al. 2011). But there are limits to the
extra costs that consumers are willing to pay for green products. A survey conducted in
Europe and the United States showed that more than 70% of consumers are willing to pay
an additional 5% for green furniture products, but if a premium exceeds 25%, only about
10% of consumers are willing to buy them (Kucher et al. 2019). That is to say, if the
premium of green furniture products leads to the loss of market competitiveness, then more
enterprises will tend to abandon the route of sustainable development and continue to
choose non-environmentally friendly materials and production methods to the
environment. Therefore, government intervention is necessary for enterprises in
implementing green manufacturing, and compliance with regulations remains the largest
single driving force for implementing green manufacturing practices (Bumgardner and
Nicholls 2020).
For the desk furniture itself, in order to show an environmentally friendly green
nature in the whole life cycle, it is necessary to organize each functional unit to conduct
effective communication and coordination in the early design and development stage (Boks
2006). In addition, 90% of the production costs can be controlled by product design
(Cordero et al. 2010). For example, the ESCC model fully integrates effective resources
upstream and downstream of the supply chain, thus effectively reducing the consumption
of materials, water, and energy across the entire supply chain (Susanty et al. 2020). The
design decision of desk furniture needs to consider the processing energy consumption,
service life, recyclable utilization and other indicators into consideration, so as to make
decisions on the type of material of the material, the geographical location of the material
supplier, the service life of the product, the recycling of products or parts, and the
processing mode of materials (Chen et al. 2019). It is worth noting that the desk reuse
system is better than the recycling system or life extension system, because the product
must have simple design and component materials. Otherwise the recovery cost is too high.
If the product cycle is long, then the company may lose in product sales (Besch 2005).
PEER-REVIEWED ARTICLE bioresources.com
Zhu & Niu (2022). “Green materials for furniture,” BioResources 17(2), 2228-2242. 2231
However, this is only a comprehensive consideration of the enterprise's economic
performance and environmental performance, and it does not mean that the recovery of
products or parts is not important. On the contrary, that part of the abandoned resources is
still valuable. In terms of the current market environment, companies limited to producing
waste and ultimately using waste will suffer from a lack of integration of certain factors.
These factors include waste collection and transportation, the scale of business, the
industrial sector where the company operates, the amount and type of waste generated,
environmental regulations, and the level of development within a particular country. Thus,
the recycling system still needs to be further designed (Nemli et al. 2007).
EXPERIMENTAL
Target Respondents
A specially developed questionnaire was sent to 10 randomly selected Chinese
office furniture enterprises through an Internet-based questionnaire survey, covering
northern, southern and central China.
Questionnaire Design
The questionnaire was distributed to the relevant staff of office furniture enterprises
through the questionnaire star platform. The respondents have certain practical experience
in furniture production and relevant knowledge of furniture design.
The questionnaire used in this study was divided into three parts.
The first part of the questionnaire collected basic data of the respondents, such as
the province of the company, the name of the company, the scale of the company, my
position, etc.
The second part of the questionnaire, the respondents were asked to choose the
main materials and decorative materials of their company's desk products, so as to
understand the current material application trend of desk and the application trend of
decorative materials.
The third part of the questionnaire evaluated the disassembly of desk components
and the recycling of desk parts, auxiliary materials, and packaging materials. These factors
reflect the utilization status of desk materials in use and after abandonment.
Data Collection
The questionnaire title setting widely refers to the relevant literature using the same
research methods at home and abroad, and increases, decreases and modifies the
questionnaire title according to the relevance of the research content to ensure that the
questionnaire is rigorous and effective. Then the questionnaire was placed on the
Questionnaire Star platform to collect information. A total of 60 target respondents
answered the questionnaire within 3 days.
Data Analysis
The data from the questionnaires were compiled and tabulated using Microsoft
Excel to facilitate analysis. The analysis of data was conducted using the Statistical
Package for the Social Sciences (SPSS IBM, USA). A total of 60 questionnaires were
distributed and 56 were recovered, including 54 valid questionnaires, with a questionnaire
recovery rate of 90.0%. The coefficient alpha of Cronbach was 0.708, which

comprehensively shows that the data reliability quality was high and able to be used for
further analysis.
RESULTS AND DISCUSSION
Necessity of Applying Green Materials
As a major branch of furniture products, the annual consumption of office furniture
in China is very large. According to the analysis report on market prospect and investment
planning of China’s office furniture industry in 2020, the production of office furniture in
2019 was highly concentrated in eight countries that accounted for 78% of the global
production, of which China topped the list (Fig. 2). Moreover, China is also the leading
office furniture exporter at a world level, which increased its share from 35.9% in 2012 to
38.5% in 2021 of the global exports (CIFF 2022). Therefore, in the context of such a large
amount of production and export, the green development of China office furniture is
imperative. Moreover, the transformation from a linear economy model to a circular
economy model is also beneficial to enterprises, as it can improve their cost efficiency and
competitive advantage and reduce the negative impact on the environment and society
(Hartini et al. 2021).

The application of green materials in office desk furniture should be considered
from two aspects. The first aspect should be the greenness of the primary construction
materials used for the desk furniture, where materials should be considered from the whole
life cycle of products, namely the raw material preparation, the product processing and
manufacturing, the utilization, the recycling, and the waste disposal. The second aspect is
the greenness of the related materials for the desk furniture, which refers to the packaging
materials and the protective materials for transportation, in addition to the main
construction materials for the desk. The quantity and nature of these packaging materials
are closely related to the main design of the desk.

Application of main materials and decorative materials for desk
According to the questionnaire survey, the investigation results of the main
materials and decorative materials of the desk can be seen in Fig. 3. Most of the main
materials of the current desk are wood-based panels and metal materials. Materials such as
solid wood, bamboo, rattan, and cloth are utilized relatively less. The decorative materials
are primarily wood veneer and decorative paper, and a few are decorated by coating and
polyvinyl chloride (PVC) decorative film.

Use of work desk components, components, and packaging materials
The disassembly status of desk components and the recycling status of desk parts,
auxiliary materials, and packaging materials are outlined below. As can be seen in Fig. 4,
Chinese companies are aware of the recycling of furniture materials but the implementation
is still less common, bringing most manufacturers to partake in partial recycling. Among
them, 50% and 41% of the parts and auxiliary materials of the desk can be recycled
respectively, and only 29% and 33% can reach the most recyclable category. In addition,
for packaging materials, 25% of employees said that their enterprises had not considered
the recycling of packaging materials. Therefore, it can be seen that some domestic office
furniture enterprises have insufficient implementation of sustainable development. There
are obvious defects in the R&D stage of furniture and the recycling stage of furniture and
furniture packaging materials.
Analysis on the Selection of Main Materials of Desk Furniture
Structural materials
The structure of the desk is the organization or connection form of the parts to
ensure the realization of the furniture design (Ke et al. 2014). The rationality of its design
has a direct impact on the recyclability, replaceability, service life, and processing energy
consumption of office furniture. The structural materials of environmental-friendly desk

can be considered through several aspects. It is important to increase the commonality of
the parts in the desk (Hu 2020). Through the design adjustment, some parts can be
standardized and generalized to the maximum extent, which can reduce the energy
consumption of processing equipment and increase the interchangeability between parts
(Zhang 2017). Materials that can be easily damaged should be replaced by materials having
a long service life. The parts of the desk that bear impact load and cyclic load frequency
can be replaced by metal or other materials with compression and wear resistance. The
disassembly design and ductility design of the structure are considered with an aim to
simplify the processing procedure and improve the reuse rate of materials (Ren and Wang
2018). Finally, it is important to consider the application of recycled materials and new
materials. For example, the new type of ecological composite board made from wood-
based panel compressed with sawdust, furniture boards made from crop residue, and wood
plastic composite materials can improve the utilization rate and reduce the cost of the
materials (Jiang 2018; Tian and Zhu 2020).
Decorative materials
The surface decoration material of the desk can keep the desk stain and warping
resistant, protect the structural stability of furniture, and improve the service life of
furniture through its characteristics of wear resistance, water resistance, heat resistance,
and chemical corrosion resistance (Sun and Liu 2019). It is one of the indispensable
materials for furniture production but at the same time hard to avoid the negative impact
on the environment. Common decorative materials include coatings, decorative paper,
thermosetting resin impregnated paper, high pressure decorative laminate, and PVC
decorative film. With the continuous improvement of technology, there are many new
decorative materials and decorative technology emerging in the market. For example,
spinning cup electrostatic spraying technology and low-temperature powder electrostatic
spraying technology on the surface of wooden products and plastic film-reinforced flexible
decorative veneer preparation technology are new methods described by Peng et al. (2021).
Upgrading the technology from the original decoration materials can help overcome the
prominent problems of the original materials, simplify the processing procedures to a
certain extent, reduce the release of harmful gases, and improve the environmental
performance.
Auxiliary materials
The commonly used auxiliary materials of desk furniture include hardware
connectors, plastic connectors, adhesives, etc. The life cycle assessment-based on auxiliary
materials shows that the environmental impact caused by metal materials such as handles,
guide rails and hinges are higher than that of other materials (Liu et al. 2019). Considering
the high cost of hardware, the quantity and type of hardware shall be reasonably applied in
the production and design of desk, and the recycling work shall be done well. But some
parts such as plastic foot pads and plastic inset nuts are not easily recyclable, so it is
recommended to ask suppliers provide degradable materials whenever possible (Zhang and
Lou 2006). In addition, the impact of glue on the environment cannot be ignored, usually
hot melt glue, multiple-use glue, white latex, and resin glue (Tong et al. 2018). According
to the current application situation, formaldehyde synthetic resin adhesives cannot be
completely abandoned in the Chinese furniture market, but the application proportion of
environmental-friendly adhesives such as formaldehyde-free adhesives and biomass-based
adhesives is expanding (Ma et al. 2020).
PEER-REVIEWED ARTICLE bioresources.com

Analysis of Packaging Materials of Desk Furniture
Furniture packaging generally plays a role in protecting furniture and facilitating
transportation. Green packaging is environmentally-friendly and it has certain publicity
value. Relevant research shows that green packaging has a positive impact on consumers’
purchase intention and behavior. In addition to satisfying customers’ green consumption
psychology to reduce the negative impact on the environment, green packaging also can
enhance the enterprises brand image value and influence (Moorthy et al. 2021). The current
office furniture packaging materials include internal cushioning materials and external
wrapping materials. Based on the continuous improvement of preparation technology and
material properties, the external wrapping material presents the trend of thin-walled and
quantity reduced design (Li et al. 2018). The commonly used materials are corrugated
paper, honeycomb paper, wooden frame, and plastic products, among others. The internal
cushioning materials are also developing towards low cost and high utilization. The
commonly used materials are air cushion, bead cotton, foam board, foam plastic, and
wastepaper (Zhou et al. 2019). In addition, as green packaging research progresses, new
applicable green materials continue to improve. Research by Li et al. (2021) shows that
long-chain branched polylactide (LCB-PLA) foam is a completely biodegradable foam that
is environmentally friendly, lightweight, and heat-resistant. Long-chain branched
polylactide is an ideal substitute for non-degradable petroleum-based plastics.
Alternatively, Allaf and Futian (2020) used wood waste to prepare green packaging
composites and found that poly -caprolactone)/sawdust-wood plastic composites
(PCL/SD-WPCs) can potentially replace traditional plastic packaging applications.
The selection of office furniture packaging materials needs to consider many
factors, one of which is the degradability and recyclability of the materials. Packaging itself
is specially designed for the logistics and transportation of products, and most of them are
disposable products with a huge demand. It is necessary to improve the recycling
mechanism or select degradable green materials to make full use of resources and reduce
the impact on the environment. Secondly, the rationality of packaging material protection
is also worth considering. The basic purpose of packaging is to protect the furniture in the
process of transportation, but also to avoid the waste caused by excessive packaging. Third,
the environmental-friendly packaging materials cannot be ignored. Green packaging
materials should be sourced from a variety of suppliers, have low energy consumption,
possess easy recyclability and recycling efficiency, and have a minimal environmental
impact in the preparation and disposal processes (Li and Sun 2019). Polystyrene films such
as polystyrene foam as cushioning gaskets and wrapped products in furniture packaging
have been banned or restricted by many countries for environmental reasons (Shi and Zhou
2018).
FINDINGS
Materials Serve Functions
The desk is a functional furniture piece, and the application of materials needs to
serve the function. Since people began to pay attention to humanized design, the functions
of the desk began to expand to include desktop lifting functions, timing functions, and
screen lifting functions, among others. Subsequently, the materials of the desk are also
gradually changing, from the original single material to a variety of materials (Fig. 5).
Therefore, the application of desk materials should consider the changes of functional
PEER-REVIEWED ARTICLE bioresources.com

trend. Currently, the office mode is affected by two main factors. One factor is the impact
of the intelligent era (Wu et al. 2017).
Fig. 5. Changes in the office. a) open office in the middle of the last century, b) modern open office,

Smart furniture is rapidly evolving in terms of technology and product intelligence,
which provides unlimited possibilities for the development of office furniture in the future
(Xiong et al. 2021). The second factor is the influence of the Coronavirus Disease 2019
(COVID-19). Affected by COVID-19, the introduction rate of telecommuting in
worldwide enterprises has further increased, especially in Chinese enterprises (Cui and
Jiang 2021). Telecommuting market of China is still in the enlightenment stage, unlike
developed countries such as the United States and Japan, which have a certain market
foundation. When forced by the epidemic situation, many enterprises and employees felt
the benefits of the "on-site + remote" mixed office mode in the process, which promoted
the rapid development of telecommuting market of China and showed a trend of
normalized development (Jia et al. 2021). This means that the area of group office will be
reduced to a certain extent, the number of home office will increase, and the office demand
will change further in the future (Chen and Qi 2020). The application of green materials
needs to follow the trend under the overall planning of green design, constantly explore
new materials and meet the changes of functions.
Energy Conservation during Material Processing
In the furniture supply chain, one of the processes having the highest carbon
emission output is the material processing (Chen et al. 2019). In addition to avoiding the
use of heavy metals, fluorine-containing compounds, and other pollutants in the raw
materials themselves, material processing equipment and facilities should also be adjusted
to reduce the energy consumption and the output of pollutants. Many large furniture
companies have started sustainable energy projects, such as Haworth’s solar panel
renewable energy project, Herman Miller’s water recycling and reuse, and Sunon’s solar
photovoltaic power generation production. These projects have achieved considerable
results in reducing carbon emissions and saving energy. Small enterprises do not have the
ability to start large-scale environmental projects, so they need national policies to
encourage and guide enterprises’ independent innovation, strive to solve the coordination
problems of technology introduction and technological innovation, and promote
enterprises to complete green transformation (Liu and Zhang 2019).

Recycling of Waste Materials
Many studies have shown that, compared with new products, the remanufacturing
operation of old goods can achieve the purpose of saving energy, saving cost and improving
material efficiency (Abbey et al. 2015). As we all know, statically designed products will
be eliminated in the process of continuous innovation and iteration. However, this cannot
be defined as the elimination of materials. It can meet the needs of the current market
through redesign and remanufacturing. At the same time, it also saves the material cost and
processing cost for the company. Combined lifecycle evaluations of each component
suggest that across the actual realized life of the constituent materials, multiple
remanufacturing cycles in each case lower the total environmental impacts beyond what
was achieved in the initial remanufacturing cycle; in other words, total environmental
benefit increases with the number of remanufacturing cycles (Krystofik et al. 2017). For
desk furniture, the service life is often longer than the enterprise that buys and uses it, so it
has a high value of recycling and remanufacturing. For materials with a high degree of
damage, they can be reused indirectly or used to generate energy (Luo and Xu 2016). For
example, wood-based panels with a high usage rate can be used as raw materials for other
panels such as recycled fiberboard or wood-plastic composite materials. Wood-based
panels can also have potential industrial applications such as in the pulp and paper industry,
and they can also be used as fuel for energy supply (He and Mu 2008).
CONCLUSIONS
1. As the material basis of the product system, green materials are a key step for office
furniture enterprises to achieve sustainable development. With the global advocacy of
the concept of sustainable development and the support and guidance of national
policies, the popularity and practical operation of green concept in Chinese domestic
office furniture enterprises are gradually increasing, and most enterprises are beginning
to pay attention to the application of green materials.
2. Through the analysis of the implementation of the concept of sustainable development
by worldwide office furniture enterprises, it is concluded that the Chinese domestic
high-end office furniture brands have a high degree of implementation of green
development, making the products contain very little or no materials that have a
negative impact on the environment, which approaches developed countries such as
European countries, the United States and Japan, where enterprises commonly have
higher environmental consciousness and most of leading furniture enterprises can
ensure that their products do not contain materials harmful to the environment. While
the implementation degree of middle and low-end brands in China is relatively low,
which cannot ensure the green of materials for the whole line of products.
3. The selection of structural materials, decorative materials and auxiliary materials of the
desk should be comprehensively considered from the aspects of service life,
recyclability and reusability in combination with the economic performance of the
company, so as to achieve the situation of mutual benefit between enterprise
development and ecological conservation. Most of the packaging materials of the desk
are disposable products, which should be recycled and reused to protect the
environment and save resources at the same time.

4. Desk furniture materials should keep up with the development trend. The new
environmental-friendly materials should be constantly explored and developed together
with the design innovation and technological innovation of desk products.

Wood surface treatment aims to improve or reduce the surface activity of wood by physical treatment, chemical treatment, biological activation treatment or other methods to achieve the purpose of surface modification. After wood surface modification, the paint film adhesion performance, gluing performance, surface wettability, surface free energy and surface visual properties would be affected. This article aims to explore the effects of different modification methods on the adhesion of wood coating films. Modification of the wood surface significantly improves the adhesion properties of the paint film, thereby extending the service life of the coating. Research showed that physical external force modification improved the hydrophilicity and wettability of wood by changing its surface structure and texture, thus enhancing the adhesion of the coating. Additionally, high-temperature heat treatment modification reduced the risk of coating cracking and peeling by eliminating stress and moisture within the wood. Chemical impregnation modification utilized the different properties of organic and inorganic substances to improve the stability and durability of wood. Organic impregnation effectively filled the wood cell wall and increased its density, while inorganic impregnation enhanced the adhesion of the coating by forming stable chemical bonds. Composite modification methods combined the advantages of the above technologies and significantly improved the comprehensive properties of wood through multiple modification treatments, showing superior adhesion and durability. Comprehensive analysis indicated that selecting the appropriate modification method was key for different wood types and application environments.

Food packaging is a crucial domain of green design and serves as an important channel for conveying green concepts to consumers. Effective packaging design not only achieves environmental sustainability but also fosters green awareness among consumers, promoting sustainable development. Therefore, it is essential to explore the relationship between food packaging design and consumers’ perception of green concepts. To enhance the influence of food packaging on consumers’ green awareness and stimulate their environmentally conscious behaviors, this study employs a literature review and case analysis to extract the key elements of green design in food packaging and the common green concepts they convey. Using the conjoint analysis method (CAM), various combinations of representative elements were established and used to design sample packaging. Through questionnaire evaluation and user interviews, the study examined the differences in the strength of influence that various elements and their combinations have on consumers’ perception of green concepts. The results reveal that, among all factors affecting consumers’ perception of green concepts in food packaging, color is the most effective and direct way to communicate green information and evoke green awareness. This is followed by material, structure, text, and patterns. The combination of material and structure is the most effective way for users to perceive green concepts, while the combination of color and structure is the least effective. Consumers are most likely to associate biodegradable materials with green concepts. This study furtherly elucidates the relationship between green food packaging design and consumers’ green awareness and offers practical design strategies for embedding green concepts in food packaging by focusing on the selection of color, material, and structure to express different types of green ideas.

Ultra-Violet (UV) coatings are widely adaptable of substrates and produce low emissions of volatile organic compounds. UV coatings can extend service life by adding self-healing microcapsules that restore integrity after sustaining damage. In this study, UV coating was used as a core material; microcapsules were produced and added to the UV coating to enhance its self-healing property, providing a good protection for both the UV coating and the substrate. UV primer microcapsules were prepared with UV primer as the core material and melamine formaldehyde resin as the wall material. The UV primer containing more than 98.0% solids content was mainly composed of epoxy acrylic resin, polyester acrylic resin, trihydroxy methacrylate, trimethyl methacrylate, and photo initiator. The preparation process of the UV primer microcapsules was optimized. Further, the UV coating was prepared with better UV primer microcapsules, and the effects of the UV primer microcapsules alongside the comprehensive properties of the coating were studied. The best preparation process for the UV primer microcapsules was as follows: the wall-core mass ratio was 1:0.50, Triton X-100 and Span-20 as emulsifiers with an HLB value of 10.04, the microcapsule reaction temperature was 70 °C, and the reaction time of the was 3.0 h. When the quantity of the UV primer microcapsules increased in the coating, color difference ΔE of the coating increased, gloss decreased, transmittance decreased, elongation at break increased and then decreased, roughness increased, and self-healing rate first increased and then decreased. When the addition of the UV primer microcapsules reached 2.0%, the color difference ΔE of the coating was 1.71, the gloss was 106.63 GU, the transmittance was 78.80%, the elongation at break was 3.62%, the roughness was 0.204 μm, and the self-healing rate was 28.56%, which were the best comprehensive properties of the UV primer. To improve the comprehensive properties of the UV coatings, the UV coatings were modified by a microcapsule technology, which gave the UV coatings a better self-healing property. The application range of microcapsules for the UV coatings was broadened. Based on the previous research of microcapsules in UV coatings, the results further refined the study of the effects of adding self-healing microcapsules to UV coatings using the UV coating itself as the core material.

This study focuses on Xuanwu Lake Park and Purple Mountain National Forest Park in Nanjing to explore the impact of leisure furniture as a single landscape element on the visual landscape evaluation and sustainable tourism experience. In previous studies, researchers paid more attention to the overall beauty of landscape and its impact on tourists’ experiences, and there was a lack of studies on the role of a single landscape element (such as leisure furniture) in enhancing landscape beauty and tourists’ experiences. This study addresses gaps in the literature by isolating leisure furniture from other landscape elements in order to assess its unique contribution to aesthetic appeal and the various dimensions of a sustainable tourism experience, including sensory, emotional, cognitive, and operational aspects. Using Schmitt’s five-dimensional Strategic Experiential Model as the framework and combining the dual methods of visual assessments and visitor surveys, an assessment team consisting of 40 members was formed to evaluate the visual landscape of leisure furniture in two major scenic spots, and 492 valid questionnaires were collected and analyzed to study the impact of leisure furniture on tourists’ experiences. The findings reveal that leisure furniture significantly enhances visitors’ aesthetic evaluations and sensory experiences at Xuanwu Lake National Forest Park. However, suboptimally designed leisure furniture at Purple Mountain National Forest Park negatively affects both the visual appeal and sensory experience of visitors. Nevertheless, in both locations, leisure furniture positively impacts emotional and operational experiences, highlighting its role in promoting relaxation and interaction among visitors. This study provides practical insights for landscape designers and urban planners regarding the importance of carefully designing and positioning leisure furniture to optimize aesthetic and experiential outcomes. It also provides certain enlightenment and insights for future exploration of the impacts of other landscape elements (such as vegetation, water, lighting, etc.) on visual landscape evaluations and visitors’ experiences.

This study experimentally investigated the effects of selected factors on the bending moment capacity (BMC) of case furniture joints. The main aim was to explore mixed applications of wood-based materials and fasteners in manufacturing case furniture to reduce material costs. The study examined the effects of the face member material—particle board (PB), plywood (PL), and block board (BB)—edge member material (PB, PL, and BB), and joint shape (T-shape and L-shape) on BMC. Additionally, the study evaluated the effects of joint type (two eccentrics (TE), two dowels (TD), and one eccentric and one dowel (ED)), and material type (PB, PL, and BB) on BMC for L-shaped joints. The results showed that joint shape and face member material significantly affected the BMC of case furniture joint. The BMCs of T-shaped joints were significantly greater than those of L-shaped joints, regardless of the material of the face and edge members, except when the face member was made of PL. For L-shaped joints with PL face members, the BMCs were significantly higher compared to others. Joints constructed with TE exhibited significantly higher BMC compared to ED and TD for the same material type. For PB, TE joints exhibited an increase of approximately 3.0 Nm and 2.0 Nm compared to TD and ED, respectively. For PL, TE showed an increase of 9.1 Nm and 4.1 Nm compared to ED and TD, respectively. For BB, the increases were 7.0 Nm and 6.6 Nm compared to ED and TD. The BMC of joints made with PL and constructed with TE and ED was significantly greater than those of BB, followed by PB. However, for joints assembled with TD, there was no significant difference among the three materials. The ratios of BMC for joints constructed with ED compared to the half-sum of TE and TD were 0.73, 1.04, and 0.79 for PB, PL, and BB, respectively. These results suggest that the face member material predominantly influences the BMC of case furniture joints, indicating the potential to reduce costs by combining different materials and joint types.

This study aimed to address the demand for furniture by developing a user-oriented design pathway for intelligent furniture products, using dining tables as a case study. According to Maslow’s hierarchy, the user needs are classified, and then the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to calculate the causal relationship, as well as the centrality and weight of each demand. The logical relationship between these factors was analyzed with Interpretive Structural Modeling (ISM) to create a hierarchical logic diagram. To ensure the feasibility of the theoretical framework, the System Usability Scale (SUS) was used for evaluation. This study systematically sorted out the logical relationship and hierarchical structure in the table demand system and identified the core elements and factor categories in the table design. The results confirmed that this design pathway effectively met user needs for dining furniture and provided practical guidance for developing the same type of furniture products, offering valuable reference for similar design endeavors.

In order to investigate the effect of thermochromic microcapsules on the surface coating performance of basswood board, two types of microcapsules prepared with syringaldehyde and sodium tripolyphosphate crosslinking agents were added to a UV primer and coated on the surface of basswood board. The color-change effect of the surface coating on basswood board with microcapsules added with syringaldehyde as the crosslinking agent was better than that with microcapsules added with sodium tripolyphosphate as the crosslinking agent, and the color difference varied more significantly with temperature. The effect of the two types of microcapsules on the glossiness of the surface coating on basswood board was relatively weak. The glossiness of the surface coating on basswood board with microcapsules containing syringaldehyde as the crosslinking agent showed an overall increasing trend with the increase in microcapsules, and the change trend was relatively gentle. The glossiness of the surface coating on basswood board with microcapsules containing sodium tripolyphosphate as the crosslinking agent increased first and then decreased as the amount of microcapsules added increased. The addition of microcapsules with syringaldehyde as the crosslinking agent had no significant effect on the reflectance in the visible light band of the surface coating on basswood board. Among the two groups of samples, the hardness increase in the surface coating on basswood board with syringaldehyde as the crosslinking agent was more significant. The adhesion level of the coating on the surface of the basswood board with the two microcapsules did not change. Neither of the microcapsules had a significant effect on the impact resistance of the surface on basswood board. In the comprehensive analysis, the surface coating on basswood board with microcapsules added with syringaldehyde as the crosslinking agent at a content of 4.0% had better comprehensive performance, better surface morphology, better color-change effect, and moderate mechanical properties. The color difference was found to be 21.0 at 25 °C, the reflectivity was found to be 57.06%, the hardness was found to be 3H, the adhesion was found to be five, and the impact resistance was found to be three.

This study aimed to investigate the characteristic values of the human-seat interface in a normal sitting posture, and to numerically mode the load on the chair seat for the structural design of chairs. The stress distributions and the characteristic values of seat were measured under normal sitting posture by using a human body pressure distribution measurement system considering the effects of gender and body mass index (BMI). The stress distribution on the seat was then numerically modeled using three modeling methods. The observed results and the numerical analysisresults were compared. The results showed that an inverted U-shaped pressure distribution was observed in normal sitting posture. The stress was concentrated on the ischial tuberosity with a maximum value of 0.066 MPa. The ratio of the load on the seat to the gravity of the human body weight was about 65.3%. The numerical model established using the body pressure mapping method was superior to those of the uniform load method and the standard loading pad method in terms of stress distribution, maximum stress, and contact area.

This research considers the ecosystem services associated with furniture, one of the leading types of secondary wood products manufactured internationally. We review and synthesize the literature surrounding the sustainable design, use, and disposition of wood furniture and related products in global markets. We consider emerging and innovative design strategies for wood (in biomimicry, for example) as well as topics that have been gaining traction in recent years (i.e., green supply chain management and eco/environmental labels and related market communications). An overarching theme is to consider how firm competitiveness can be influenced, or even enhanced, by green practices in design and associated communications with consumers. With a trend toward increasing customization in the secondary wood product marketplace, the role of design might be changing. However, design remains a critical product development function in modern markets, and designers are well-positioned to influence sustainable material utilization and improve furniture product use and lifespan.

Herein, wood plastic composites (WPCs) composed of sawdust (SD) and poly(ε-caprolactone) (PCL) with various compositions were prepared. Two compounding techniques, namely, extrusion and cryomilling, were utilized to prepare WPC raw material pellets and powders, respectively, for comparison purposes. Flat pressing was further utilized to prepare WPC films for testing. Morphological, structural, thermal, mechanical, and surface wettability properties were investigated. Results indicate the advantages of cryomilling in producing WPCs. Scanning electron microscopy (SEM) along with optical micrographs revealed well ground SD particles and uniform distribution in the PCL matrix. Tensile strength and elongation at break of the composites declined with increasing SD content, however, the modulus of elasticity significantly increased. Water contact angles averaged less than 90°, implying partial wetting. Visual observations and thermo-gravimetric analysis (TGA) indicated thermal stability of composites during processing. In conclusion, PCL/SD WPC is a potential candidate to replace conventional plastics for packaging applications. This would also provide a much better utilization of the currently undervalued wood waste resources.

This study discusses the identification of factors affecting consumers’ willingness to pay a price premium for ecological goods. The study was carried out in selected regions of Ukraine, in the cities of Kharkiv and Kyiv. The study applied various research methods, in particular public opinion analysis based on conducted surveys and the statistical inference method. The conducted research may constitute the scientific basis for the assessment of this market segment development. The comparison of consumer attitudes, presented by the residents of major Ukrainian cities regarding environmental goods, revealed their willingness to pay a price premium depending primarily on the purchasing power of the population, but also on gender, age, and social status. The analysis of differences in the cross-tabulation of quality characteristics was performed using Pearson’s chi-square test, which showed that, for example, men were more willing than women to choose environmental products due to their environmental safety and their selection was more often than in case of women based on environmental goods’ price. The collected research results can be used to assess the development prospects of environmental goods’ market, to construct the set of measures increasing the willingness level of domestic consumers to pay a price premium for ecological products, and to take up decisions about the production of ecological goods.

Long chain branching (LCB) structures are efficiently introduced into polylactide (PLA) by employing sustainable soybean oil (SO) under the initiation of trace amount of cyclic peroxide, which displays robust foamability and heat resistance. It is discovered that with the introduction of 0.6 wt% SO, the expansion ratio and Vicat softening temperature of LCB PLA are sharply raised to 75.2-fold and 155.8 °C, respectively, which is about 17.9 and 2.6 times those of linear PLA. This is because that the amounts of LCB structures are significantly increased in LCB PLA by the addition of SO with low reactivity of internal CC bonds, which can avoid the oligomerization reaction, resulting in more dramatically improved melting strength and crystallization performance of LCB PLA. Moreover, the hydrolytic degradation of LCB PLA is largely expedited as compared to linear PLA, owing to the more rapid water permeation caused by the loose packing of LCB structures. Finally, the PLA foam tray with light weight and good heat resistance is successfully developed by using LCB PLA with 0.6 wt% SO through extrusion foaming with supercritical carbon oxide and thermoforming techniques. Hence, this research offers a green route to produce eco-friendly light-weight and high-heat-resistance LCB-PLA foam with full biodegradability, which is an ideal alternative to the non-degradable oil-based plastics in the field of disposable packaging products.

Green manufacturing is an advanced manufacturing approach, which comprehensively considers environmental impact and resource efficiency and is considered as the future direction of modern manufacturing industry. However, the current situation, technologies, and development strategies of China's green furniture manufacturing have not been comprehensively analyzed and a complete furniture industry green manufacturing technology system is lacking. Here, to fill such knowledge gap, through an extensive review of literatures on manufacturing process and implications of green furniture, which consists of data identification, initial screening, eligibility determination, and final inclusion, this study (1) analyzed the current situation and existing challenges of green furniture manufacturing in China, (2) proposed and discussed a systemic green manufacturing concept for China's furniture based on the current situation, and (3) suggested strategies corresponding to the challenges. The results show that although China has determined that the implementation of green manufacturing is the only sensible way for the development of its furniture industry, many aspects of it, such as public awareness, manufacturing technology, and legal regulations are lacking. The proposed comprehensive green manufacturing concept regarding green manufacturing includes green design, green materials selection, green processes, green packaging, green recycling, etc. The proposed strategies include developing a green manufacturing strategy for furniture enterprises, strengthening the development of green furniture products, improving the production mode of green furniture, and promoting the coordinated development of green production in furniture industry. This study will play a guiding role in promoting the implementation of green manufacturing and achieving a sustainable development of the Chinese furniture industry. Additionally, it also provides a reference for the world furniture enterprises.

Despite the growing awareness about Circular Economy (CE) in production and supply chain management, there is little evidence linking CE practices to environmental and economic performances, especially within the traditional wood furniture industry in Indonesia. As with other management practices, implementation of CE can be supported by various factors. Among these factors are the so-called environmental-oriented supply chain cooperation (ESCC) practices. The study reported in this paper has three purposes. First, to investigate how the different levels of ESCC practices will affect the CE practices across the traditional wooden furniture industry in Central Java, Indonesia; second, to investigate the relationship between varying ESCC practices (which is grouped based on the implementation of CE practices) on the CE-targeted performances; and third, to examine the role of ESCC practices as a moderating variable in the relationship between CE practices and CE-targeted performances. This study uses primary data which were collected through closed questionnaires to 190 valid samples of wooden furniture SMEs across the cities of Jepara, Kudus, Rembang, Semarang, Blora and Surakarta. The data were processed using confirmatory factor analysis (CFA), K-means clustering analysis, Multivariate Analysis of Variance (MANOVA) and regression analysis. The results indicated that, depending on the levels of ESCC practices, the SMEs could be grouped into leaders, followers and laggard, which also determined the extent to which they practised the CE principles. The study also elaborated on the interactions between ESCC and CE practices, and how these might affect the CE-targeted environmental and economic performances.

Regarding furniture manufacturing, scholars have only studied the sources of VOCs in the spraying process, yet the main concern is the release of VOCs after the completion of the manufacturing process and its impact on indoor air quality. Therefore, in this study, the sources of VOCs for the entire process of furniture manufacturing were explored and probabilistic risk models were improved. Then, the carcinogenicity and non-carcinogenic health risks to workers at nine workstations in a furniture factory were evaluated via a Monte Carlo simulation method, and the sensitivity of each exposure parameter was analyzed. The results are as follows. The various types of paints, diluents, and curing agents used in the process of spraying primer paint and spraying surface paint release VOCs, such as benzene, toluene, xylene, styrene, butanone, cyclohexanone, butyl acetate, and ethyl acetate. The glue used in the leather pasting process, the glue process, and the viscose process generates VOCs, such as dichloromethane and ethyl acetate, and the paint remover used in the cleaning process emits dichloromethane. The carcinogenic risk at each station was more than 10-6. For benzene exposure, the probability of exceeding 10-6 was greater than 95% for all stations, excluding SWB, SWP, and CWP. The carcinogenicrisk of workers exposed to benzene was the highest at SWS, at 3.07×10-6±1.73×10-6, and the carcinogenicrisk of workers exposed to dichloromethane was the greatest at SWL, with a value of 5.14×10-6±2.70×10-6. The only non-carcinogenicrisk greater than 1 was to SWS workers. The parameters that had the greatest impact on the carcinogenic risk assessment were exposure day (ED), concentration (C), exposure time (ET), and exposure frequency (EF). In the non-carcinogenic risk assessment, the most influential variables were ED, ET, and EF. In addition, concentration also had a significant impact on the evaluation results.

Remanufacturing has achieved viability in a diversity of industrial markets as a means to both maintain the value of products and minimize waste. From carpet tiling to manufacturing robots, a wide range of goods have presently established supply and consumer networks that support remanufacturing, and thus offer a point of entry into a more circular industrial economy. Based on this performance, it is reasonable to expect that remanufacturing can in some cases be made an iterative endeavor; that existing networks may be leveraged to create additional lifecycles for previously remanufactured goods at net environmental and economic gain over virgin production. This case study identifies and explores factors of Davies Office, Inc. (Davies) remanufacturing processes for office furniture that affect the economic and environmental practicality of creating multiple remanufacturing cycles. Specifically, we use Life Cycle Assessment (LCA) to estimate the impacts of multiple remanufacturing cycles and how these are affected by “adaptive remanufacturing,” a neologism to describe the use of an end-of-life (EOL) product core to create a similar, but non-identical product. LCA results suggest that adaptive remanufacturing is both an environmentally preferable and economically viable business strategy. Specifically, the ability to update, reconfigure, and customize previously obsolete products to meet present market demands enables lifecycle extension beyond what is achievable with traditional remanufacturing. In this, the study posits that such adaptive remanufacturing techniques not only expand the potential environmental benefits of remanufacturing, but enhances the long-term economic viability of remanufacturing in durable product markets.
