Purpose This paper performs a life cycle assessment study for a white wine produced in the northern part of Portugal, i.e. the white vinho verde. The purpose is to identify the environmental impacts occurring along the wine life cycle as well as the stages that mostly contribute to the environmental impact, as well as the associated causes. The sta...

This study presents an overview of options aiming to reduce emissions to air, soil and water from an aluminium die casting plant located in Portugal. We identify eighteen pollution reduction options and then estimate their potential to reduce the pollution, and the costs associated with their implementation to the die casting plant. The different t...

Industrial activities cause a variety of environmental problems. These are largely caused by emissions of air pollutants, the production of waste and depletion of natural resources. As a consequence, industrial managers face a complex problem when assessing the overall environmental pressure on the environment, and options to reduce this pressure....

This study describes a model (MIKADO) to analyse options to reduce the environmental impact of aluminium die casting. This model will take a company perspective, so that it can be used as a decision-support tool for the environmental management of a plant. MIKADO can be used to perform scenario analyses to analyse the impact on the environment of d...

This study explores a model (MIKADO) to analyse scenarios for the reduction of the environmental impact of an aluminium die casting plant. Our model calculates the potential to reduce emissions, and the costs associated with implementation of reduction options. In an earlier paper [Neto, B., Kroeze, C., Hordijk, L., Costa, C., 2008. Modelling the e...

This study identifies and assesses the main contributors to the environmental impact of dehydrated apple snacks produced through the hot air drying method, which is the most common method for dehydrating food. The study aims to fill the gap of Life Cycle Assessment (LCA) studies regarding dehydrated apple snacks produced using the hot air drying me...

The food chain is a large contributor to environmental pollution, especially greenhouse gas emissions, strongly associated with the consumption of animal-based proteins. The understanding of the negative environmental impacts of dietary habits by the population is of the utmost importance to provide the means to effect change to more sustainable ea...

The Sustainable Food Production and Consumption Working Group of the Sustainable Campus Network (RCS) participated, in 2020/21, in a survey of Higher Education Institutions (HEIs) in Portugal. One of the sections of this survey aimed to better understand what is happening in HEIs in terms of the food service sustainability.Food Production and Consu...

It is now undeniable that human relationship with the planet is sick. The most effective approach to restrict the degradation of ecosystems is to significantly change human consumption patterns toward more sustainable ones. The amount of waste generated is the result of the consumption society that emerged in the second half of the twentieth centur...

The end of life of pharmaceutical products through environmentally unsafe routes is a growing concern in our society. However, the studies reported so far, apart from being limited in number, do not reflect the current management practices for the end-of-life management of pharmaceuticals. Published work lacks an in-depth analysis in focusing on th...

This Special Issue (SI) “Sustainable Food Production and Consumption” intends to be the union of multidisciplinary areas of knowledge, under the sustainability pillar, based on knowledge about one of the most relevant agents for overall environmental impacts: food production and consumption [...]

The concern about sustainability is growing and the Mediterranean Diet has been extensively identified as a promising model, with benefits for human and environmental health. This systematic review aims to identify and describe the indicators which have been used to evaluate the sustainability of the Mediterranean Diet and the results from their ap...

Paper aims: To define and evaluate the environmental performance of the implementation of reverse logistics (RL) for empty pesticide plastic containers (EPPC) in Brazil through the Campo Limpo System (CLS). Originality: Discussion about the implementation of RL for the development of sustainable systems, through the identification of environmental...

This paper compares the environmental impacts of the operation of a novel Gas-to-Liquid (GtL) process for synthetic crude oil production with conventional crude oil production. This process uses novel microreactor technology (NetMIX) applied in Steam Methane Reforming and Fischer-Tropsch (FT-SMR) for the conversion of associated gas originated on o...

Medical devices (MDs) are important health instruments, encompassing an enormous diversity of products, from simple ligatures to pacemakers, bone grafts or auxiliary life support machines. Despite the growing social and economic relevance of the MD industry in the health sector, its environmental problems have only recently started to be discussed....

PurposeBacterial cellulose (BC), obtained by fermentation, is an innovative and promising material with a broad spectrum of potential applications. Despite the increasing efforts towards its industrialization, a deeper understanding of the environmental impact related to the BC production process is still required. This work aimed at quantifying th...

This paper aims to present the interdisciplinary interactions between design students (Master in Product and Industrial Design-MDIP) and engineering students (Integrated Master in Environmental Engineering-MIEA) at the Faculty of Engineering of the University of Porto (FEUP), Portugal, through the development of an academic project based on the env...

Purpose Aquaculture is the best alternative to fulfil global fish demand, however it still relies heavily on fisheries-derived products for aquafeeds production. This study assesses and compares the environmental impacts of producing four experimental diets to gilthead seabream with different dietary protein (P) to carbohydrate (CH) ratios (P50/CH1...

Sustainability is a relevant and transversal theme of knowledge, but so far it is taught only in few faculties of the University of Porto (UPorto). To our understanding the sustainability concept (as a whole or focusing on one of its three pillars: environment, social and economic), is in its own a sound theme to bring together students from differ...

Green Public Procurement (GPP) is currently being used to influence the market to shift to a supply of goods and services to the public sector that have a reduced environmental impact. The food service sector plays a major role in the purchases made by the public sector and due to that relevance deserves attention. The GPP schemes reviewed were tho...

Natural gas (NG) from shale formations (or shale gas) is an unconventional energy resource whose potential environmental impacts are still not adequately assessed. Hence, this study performs a Life Cycle Assessment (LCA) of shale gas considering a gas well under appraisal in Burgos, Spain. An attributional model was developed, considering the NG pr...
