Beyond Mechanical Recycling: Giving New Life to Plastic Waste

Angewandte Chemie International Edition, Journal Year: 2020, Volume and Issue: 59(36), P. 15402 - 15423

Published: March 11, 2020

Abstract Increasing the stream of recycled plastic necessitates an approach beyond traditional recycling via melting and re‐extrusion. Various chemical processes have great potential to enhance rates. In this Review, a summary various routes assessment life‐cycle analysis is complemented by extensive list developed companies active in recycling. We show that each currently available applicable for specific waste streams. Thus, only combination different technologies can address problem. Research should focus on more realistic, contaminated mixed streams, while collection sorting infrastructure will need be improved, is, stricter regulation. This Review aims inspire both science innovation production higher value quality products from suitable reuse or valorization create necessary economic environmental push circular economy.

Mechanical Recycling of Packaging Plastics: A Review

Macromolecular Rapid Communications, Journal Year: 2020, Volume and Issue: 42(3)

Published: Sept. 30, 2020

Abstract The current global plastics economy is highly linear, with the exceptional performance and low carbon footprint of polymeric materials at odds dramatic increases in plastic waste. Transitioning to a circular that retains its highest value condition essential reduce environmental impacts, promoting reduction, reuse, recycling. Mechanical recycling an tool environmentally economically sustainable plastics, but mechanical processes are limited by cost, degradation properties, inconsistent quality products. This review covers methods challenges for five main packaging plastics: poly(ethylene terephthalate), polyethylene, polypropylene, polystyrene, poly(vinyl chloride) through lens economy. Their reprocessing induced mechanisms introduced strategies improve their discussed. Additionally, this briefly examines approaches polymer blending mixed waste streams applications lower recyclate.

Microbial Degradation and Valorization of Plastic Wastes

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: April 21, 2020

Growing accumulation of plastic wastes has become a severe environmental and social issue. It is urgent to develop innovative approaches for disposal wastes. Recently, reports on biodegradation synthetic plastics by microorganisms or enzymes spring up, which arouses our great enthusiasms the biological treatment technology In this review, we comprehensively summarize that have been reported be able degrade variety generally used such as polyethylene (PE), polystyrene (PS), polypropylene (PP), polyvinyl chloride (PVC), polyurethane (PUR) terephthalate (PET). addition, highlight microbial metabolic pathways oligomers monomers styrene, terephthalic acid (TPA) ethylene glycol (EG), current attempts towards utilization feedstocks production chemicals with high value. Taken together, these findings will contribute build conception bio-upcycling connecting biosynthesis valuable in microorganisms. Last but not least, discuss challenges toward degradation valorization

The Chemical Recycling of Polyesters for a Circular Plastics Economy: Challenges and Emerging Opportunities

ChemSusChem, Journal Year: 2021, Volume and Issue: 14(19), P. 4041 - 4070

Published: April 7, 2021

Abstract Whilst plastics have played an instrumental role in human development, growing environmental concerns led to increasing public scrutiny and demands for outright bans. This has stimulated considerable research into renewable alternatives, more recently, the development of alternative waste management strategies. Herein, aim was highlight recent developments catalytic chemical recycling two commercial polyesters, namely poly(lactic acid) (PLA) poly(ethylene terephthalate) (PET). The concept is first introduced, associated opportunities/challenges are discussed within context governing depolymerisation thermodynamics. Chemical methods PLA PET then discussed, with a particular focus on upcycling use metal‐based catalysts. Finally, attention shifts emergence new materials potential modernise economy. Emerging opportunities challenges industrial feasibility.
