Abstract

The aim of this study was to examine whether a decline in microbial activity (i.e., CO2 output) during the biodegradation of municipal solid waste (MSW) indicated an end to biodegradation and the appearance of a stable, final product. As the organic fraction of MSW was biodegraded in an 8 clamp Cambridge Batch System composter, CO2 output declined by 50% and moisture content at the end of the process was 2/kg dry matter (DM)) which exceeded draft EU biowaste directive (2001) guidelines (10,000 mg O2/kg DM).
