Scope: What is ISO 13975 - Ultimate anaerobic biodegradability of plastic materials in controlled slurry digestion systems about? ISO 13975 specifies a method of evaluating the ultimate anaerobic biodegradability of plastic materials in a controlled anaerobic slurry digestion system with a solids concentration not exceeding 15 %, which is often found for the treatment of sewage sludge, livestock fences, or garbage. The test method is designed to yield a percentage and rate of conversion of the organic carbon in the test materials to carbon dioxide and methane produced as biogas. ISO 13975 applies to the following materials, provided they have a known carbon content:
