Aerobic Biodegradability by Respirometry ISO 14851
topic
Aerobic biodegradability testing inoculates textile material specimens with activated sewage sludge or soil microorganisms in aqueous mineral medium, measuring oxygen consumption by electrolytic respirometry or CO2 evolution by infrared detection over 28 to 180 days and calculating percentage theoretical oxygen demand mineralised as the biodegradation degree.
Role
Provides internationally standardised aerobic biodegradation data for bio-based textile fibres and biodegradable finishing treatments, enabling comparison against the 60 to 90 percent mineralisation thresholds required for OECD biodegradable claims and supporting environmental product differentiation for sustainable fibre brands.
