Ultimate Anaerobic Biodegradability

A method of the assessment of the ultimate anaerobic biodegradability of plastic materials in a controlled anaerobic slurry digestion system with a solids concentration of less than 15% has been described. Such a solid concentration is often at the treatment of [Pg.21]

In another study, the ultimate anaerobic biodegradability and disintegration under high-solids anaerobic digestion was evaluated based on carbon conversion of the test substance to methane and carbon dioxide after 45 days, according to ISO 15985 [3]. Figure 29.8 shows that anaerobic decomposition of PLA occurs at 52 dz 2°C under high-solids and static, nonmixed conditions. [Pg.472]

The aquatic, anaerobic biodegradation test was first published by the European Centre for Ecotoxicology and Toxicology of Chemicals Technical Report No.28 [10]. Later, more or less the same procedure was adopted as ASTM D5210 in 1992 and ISO 11734 in 1995. Within the field of bioplastics a new version with some minor modifications was published in 2005 as ISO 14853- Plastics - Determination of the ultimate anaerobic biodegradability in an aqueous system - Method by measurement of biogas production.
