Application Summary AI generated

This standard specifies a test method for determining the extent to which plastic materials biodegrade under high-solids anaerobic digestion conditions, simulating environments like commercial or municipal solid waste treatment facilities. It is applied by measuring the volume and composition of biogas (methane and carbon dioxide) released from plastic samples incubated with high-solids inoculum, providing data for assessing the environmental fate of plastics in anaerobic bioreactors or landfills. The standard is primarily used in the plastics industry, waste management research, and product certification to evaluate the biodegradability of packaging, agricultural films, or compostable items under realistic high-solids anaerobic conditions.
