A new strategy to prepare fully bio-based poly(lactic acid) composite with high flame retardancy, UV resistance, and rapid degradation in soil

Yuchun Li et al.

Summary: A fully bio-based additive (PA@CHTM) with a core-shell structure was synthesized to enhance the mechanical properties, flame retardancy, and UV-blocking performance of PLA, while accelerating its degradation in soil. With 9 wt% of PA@CHTM added, the oxygen index value, UL-94 test grade, and Young's modulus of PLA were significantly improved, and the photoaging process was delayed.

Degradation of polylactic acid/polybutylene adipate-co-terephthalate by coculture of Pseudomonas mendocina and Actinomucor elegans

Hao Jia et al.

Summary: Cocultivation of Pseudomonas mendocina with Actinomucor elegans significantly improved the biodegradation of PLA/PBAT films by producing an efficient enzyme system. The protease and lipase activity of the coculture exceeded that of the monoculture, leading to a higher degradation rate of PLA/PBAT films.

Near-complete depolymerization of polyesters with nano-dispersed enzymes

Christopher Delre et al.

Summary: By dispersing enzymes with deep active sites, semi-crystalline polyesters can be efficiently degraded in a short period of time, with up to 98% conversion of polyester to small molecules. This method allows for complete elimination of the need to separate and landfill products in compost facilities, with degradation achieved in standard soil composts and household tap water.
