The random disposal and immature recycling of post-consumer polyethylene terephthalate (PET) packages lead to a severe threaten the ecological system owing slow natural degradation kinetics PET plastic, meanwhile cause waste carbon resources stored in plastics. Many methods have been developed recycle plastics, such as mechanical recycling, which induces reduced quality relative virgin PET. In recent years, photocatalytic conversion plastic wastes into chemicals has received considerable attention due their unique advantages, including mild conditions, less energy consumption, simple operation. this review, we summarized latest achievements photoreforming plastics value-added chemicals. Primarily, described mechanism for bond cleavage during photoreforming, emerging pretreatment methodologies advantages conversion. Then, introduced electro-/bio-assisted photocatalysis technologies commented strengths limitations. Finally, put forward challenges potential advances domain

Biofilm mitigation in hybrid chemical-biological upcycling of waste polymers

Frontiers in Bioengineering and Biotechnology, Journal Year: 2024, Volume and Issue: 12

Published: July 22, 2024

Accumulation of plastic waste in the environment is a serious global issue. To deal with this, there need for improved and more efficient methods recycling. One approach to depolymerize using pyrolysis or chemical deconstruction followed by microbial-upcycling monomers into valuable products. Microbial consortia may be able increase stability response process perturbations adapt diverse carbon sources, but likely form biofilms that foul equipment, increasing challenge harvesting cell biomass.
