Electric pulse fragmentation (EPF) is a novel comminution process where ‘lightning bolts’, or highly energetic electrical discharges, are applied to materials immersed in water. These discharges exploit the variability in electrical and acoustic properties ...
The purpose of the study is to determine the environmental and economic balance between the collection of wastes and their transport to a centralized recycling plant versus the displacement of a recycling plant near the waste source locations. Two systems ...

Photoexcited protonated tetrathiafulvalene (HTTF+) was found to act as a photosensitizer, injecting electrons into Pt microparticles (floating electrocatalysts) to produce H2 and TTF•+ in acidic acetonitrile. In addition, TTF•+ was electrochemically reduce ...
WEEE is Waste Electrical and Electronic Equipment and its proper treatment is one of the challenges Europe is facing, because of economically essential materials recovery and of proper treatment of environmentally critical components they contain (CFC, PCB ...

The accelerating rate of accumulation of electronic waste or waste electrical and electronic equipment (WEEE) is a global problem due to the environmental and health consequences. Recycling of WEEE is a sustainable solution to overcome this problem. Use of ...
Current phosphorus (P) use in European countries is highly dependent on mineral P imports and not sustainably managed. In order to identify and implement measures for sustainable P management, a comprehensive understanding of national P flows and stocks an ...
Circular economies produce virtually no waste, as materials are re-used and recycled continuously. It’s a dramatic shift from the current linear economy in which we take, make, consume and dispose – drawing regularly on natural resources to create products ...
The total municipal solid waste (MSW) generated worldwide in 2012 was approximately 1.3 billion tonnes. Were all countries to continue to generate waste at the current rate of high-income countries, total waste generation could reach 5.9 billion tonnes by ...
Production of secondary aluminium (Al) currently represents about 70% of total European Al production with a still rising trend and about 50% European final Al demand. The utilization of anthropogenic Al resources as secondary raw materials is therefore a ...
In light of the environmental consequences of linear production and consumption processes, the circular economy (CE) is gaining momentum as a concept and practice, promoting closed material cycles by focusing on multiple strategies from material recycling ...
