Solvent-free chemical upcycling of poly(bisphenol A carbonate) and poly(lactic acid) plastic waste using SBA-15-functionalized basic ionic liquids

Green Chemistry 2024 35 citations

AI summary Read the abstract

Researchers developed a solvent-free method to break down polycarbonate and polylactic acid plastic waste into their original building-block chemicals. The study used specially designed catalysts based on ionic liquids attached to a porous silica framework. The findings suggest this approach could support a more circular economy by efficiently converting plastic waste back into valuable raw materials without requiring harmful solvents.

Recent advances in chemical recycling and upcycling of plastic waste into valuable materials, chemicals, and energy: a comprehensive review

AI summary Read the abstract

A comprehensive review cataloged advanced chemical recycling and upcycling pathways—including pyrolysis, gasification, hydrocracking, and solvolysis—capable of transforming mixed plastic waste streams into circular high-value chemicals, fuels, and energy carriers. These technologies are directly relevant to microplastic pollution research because scaling chemical recycling reduces the volume of plastic that degrades into environmental microplastics, addressing the problem at the source.
