Biodegradation of Synthetic Aliphatic-Aromatic Polyesters in Soils: Linking Chemical Structure to Biodegradability.

ABSTRACT: Biodegradable aliphatic-aromatic copolyesters are commercially important and used in diverse applications, including soil-biodegradable mulch films. This work investigates the effects of copolyester chemical structure on soil biodegradability using ¹³C-labeled variants of polybutylene adipate-co-terephthalate (PBAT) and polybutylene sebacate-co-terephthalate (PBSeT), as well as ¹³C-labeled cellulose as a positive biodegradation control. Biodegradation in soil was assessed by monitoring polyester and cellulose mineralization to ¹³CO₂ throughout multimonth incubations and quantifying the nonmineralized polyester in the soil after incubations. Mass balances on polyester- and cellulose-added ¹³C over the incubations were clos
