Reductive depolymerization as an efficient methodology for the conversion of plastic waste into value-added compounds

Abstract

To avoid the negative impact of plastic on the environment and on human health and to improve the circular economy, the search for new and cost-efficient methods for the depolymerization of plastic waste into value added compounds is extremely desirable. In recent years, reductive depolymerization has emerged as an excellent alternative methodology for the valorization of plastic waste and has gained interest as it allows plastic waste to be transformed into value-added products, which cannot be obtained by other recycling processes. Catalysts can have a fundamental role in this subject. This review aims to describe the most relevant catalytic methodologies for the reductive depolymerization of polyester, polycarbonate and polyamide waste into value-added compounds.
