Plastics. Determination of the aerobic biodegradation of non-floating materials exposed to marine sediment. Method by analysis of evolved carbon dioxideWhat is ISO 22404 Plastic aerobic biodegradation about? ISO 22404 specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. ISO 22404 can also be applied to other materials. ISO 22404 is a simulation under laboratory conditions of the habitat found in a sandy tidal zone that, in marine science, is called the eulittoral zone. Biodegradation is determined by measuring the CO2 evolved by the
