Soil biodegradable polyesters are designed to undergo microbial utilization in aerobic soils, forming carbon dioxide and biomass. These thus viable substitutes for conventional, persistent polymers (e.g., polyethylene) specific applications which the transfer of some into soil is inevitable. While polymer biodegradability often assessed laboratory incubations using respirometric analysis formed CO2, approaches accurately quantify soils track their mass loss field over time remain missing. This study first introduces an analytical workflow combining Soxhlet extraction with proton nuclear magnetic resonance spectroscopy accurate, high-throughput, chemically selective quantification eight commercially important (i.e., poly(butylene adipate-co-terephthalate), polylactic acid, poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), poly(3-hydroxybutyrate-co-3-hydroxyvalerate), polycaprolactone, polybutylene adipate, azelate, succinate), nonbiodegradable polystyrene, six spanning a range types physicochemical properties. work effective sample deployment-retrieval approach that, combined method, allows biodegradation adipate-co-terephthalate) acid from mulch film three agricultural be monitored. In combination, two parts this lay foundation monitor soils.
