Waste jeans represent one of the major fractions of textile waste that is generated in millions of tons annually. Waste jeans are classified as a cotton-rich material, which can potentially become a sustainable source of raw cotton for production of new goods to tackle the shortage in cultivated cotton. In this framework, present research aims to d...

Development of a new sustainable pilot scale technology for recycling of Waste Printed Circuit Boards (WPCBs) is a challenging and time-consuming task, especially since the situation with electronic waste is worsening yearly in terms of environmental hazard and valuable material loss. Therefore, this research is oriented towards quickly approaching...

Banknote printing is the industry that has a deep influence on financial operations on market, reflecting the economic performance of governments. Therefore, it is surrounded by a great secrecy even when dealing with production waste and end-of-life products, which are utilized very carefully by controlled combustion or incineration after crushing...

Solar cell industry produces high quantities of waste in form of broken, damaged, and rejected cells, whereas milling and filtering practices are typically used to recover the valuable materials (Al, Ag and Si) from such Waste Solar Cell Wafers (WSCWs). This recycling approach has its disadvantages, e.g. excessive energy consumption and dust emissi...

Polyether block amide (PEBA) and PEBA based nanocomposites are one of the most promising materials in environmental technology, used for separation and filtration. Applications of Pebax are studied extensively, however, most of the previous studies focused on its use as a dense membrane without giving due attention to fibrous membranes. This resear...

Cotton is one of the primary resources in many modern industries and with increasing demand rates the current challenge is to find other sources of cotton production with lower prices and higher quality whereas cotton produced only by agriculture is not sufficient for these needs. This is focused on developing a new strategy to make the textile was...

Solar cell wafer industry is classified as one of the most complex electronic industries that produces a significant proportion of waste in the form of broken/damaged cells or cells having some defects in their chemical composition that can generally be called Rejected Solar Cell Wafers (RSCWs). Although these wastes contain valuable metals (e.g. S...

Waste Printed Circuit Boards (WPCBs) were classified as one of the most important resources for urban mining containing high purity Copper (Cu) and other valuable materials. Recently, a dissolution recycling approach enhanced by ultrasonic treatment succeeded in the liberation of Cu foils from WPCBs as received. This research aims to synthesize Cop...

Waste Printed Circuit Boards (WPCBs) are one of the major recycling challenges in this century with Through-Hole Solder Joint (THSJ) components representing more than 40 wt% of their metallic fraction. THSJs are composed mainly of three metals - Cu, Sn, and Pb; in addition, THSJs can contain a very small amount of Pd and other additives such as Ni,...

Multilayer Flexible Packaging Waste (MFPW) represents the largest fraction of packaging waste and is mainly composed of multiple plastic films laminated with Al foil. In the EU, mechanical and chemical recycling technologies are usually used to separate polymeric fractions from Al; however, these recycling practices have inherent crucial restrictio...

Abstract In order to achieve the goals of Circular Economy (CE) for the million tons of Waste Printed Circuit Boards (WPCBs) generated annually, this research aims to move from WPCB recycling to remanufacturing stage and use the recovered high purity Copper (Cu) as a raw material to synthesize Copper Nanoparticles (Cu-NPs) which are a high added va...

This research aims to develop a cleaner and profitable industrial technology for full recovery of metallic and non-metallic fraction of waste pharmaceutical blister packaging using switchable hydrophilicity solvents. In the developed technology, ultrasonic treatment was used to accelerate the breakage rate of adhesive bonding and molecular forces b...

Pulverization operations are extensively used in the recycling of waste printed circuit boards (WPCBs) for liberation of metal and fiberglass in powder shape. The types of liberated metals can vary greatly, for instance it can be copper, tin, lead, aluminum, nickel, gold, palladium, and so forth. However, the obtained metal and nonmetal particles r...

High recycling rate is considered the main challenge to close the loop of circular economy for the million tons of Waste Printed Circuit Boards (WPCBs) due to their complex structure. In order to achieve this goal, the current work aims to recover all metal foils and woven fiberglass layers from bare Waste Printed Circuit Board (WPCBs) “as received...

Recently, the liquid phase exfoliation of graphite has widely been used to produce graphene due to the economic profitability of the current method. However, the compressive load that appears during the exfoliation process leads to the formation of small graphite fragments in the graphite suspension. In addition, the applied shear load (responsible...

In order to increase environmental and economic benefits of waste Random Access Memory (RAM) recycling, this research aims to separate all metallic and non-metallic components of RAM by using chemical treatment and subsequent leaching process to liberate gold from gold-plated components. Chemical treatment was employed to separate metal (copper foi...

In the framework of reuse of non-metal (woven fiberglass layers (WFG) and epoxy resin (ER)) recovered from waste printed circuit boards (WPCBs) as received and maximization of economic and environmental benefits, this research aims to investigate mechanical and thermal properties of recycled woven fiberglass and ER extracted from WPCBs after separa...

Recently, the separation of waste printed circuit boards (WPCBs) using organic solvents has become more prevalent because it is an environmentally friendly and efficient technique. However, the relatively high temperatures (∼135 °C) used during the separation process lead to higher energy consumption, faster solvent degradation, and possibly higher...
