This startling mechanism for promoting depolymerization relies on an additive that many plastics already contain: a pigment called carbon black that gives plastic its black color. Through a process ...

To address this issue, recent advances have focused on developing environmentally friendly and efficient methods for polymer degradation and recycling, with deep eutectic solvents (DESs) acting as ...

Substantial efforts are being made to advance recycling technologies, transforming discarded plastics into raw materials that can be reused. Chemical recycling emerges as a major frontier in this ...

Depolymerization process. By employing high pressure, reactor operators can achieve highly efficient depolymerization of polyethylene (PE) of varying densities or polypropylene (PP). The pressure ...

Lignin, a renewable aromatic biopolymer with complex three-dimensional networks and diverse functional groups, represents a promising sustainable feedstock for value-added chemicals and fuels. However ...

Researchers have shown that a common plastic additive called carbon black can depolymerize polystyrene and polyvinyl chloride (PVC), two of the least recycled plastics in the planet’s waste stream It ...

Lake County Board members went back and forth Tuesday over language in the Solid Waste Management Plan Update on a technology taking the recycling world by storm, “depolymerization,” a type of plastic ...
