Aerobic biodegradation of plastic materials under controlled composting conditions, incorporating thermophilic temperatures
ASTM D-5338-15 test method is equivalent to ISO 14855, which determines the degree and rate of aerobic biodegradation of plastic materials on exposure to a controlled-composting environment under laboratory conditions, at thermophilic temperatures. This test substances are exposed to an inoculum that is derived from compost from municipal solid waste. The aerobic composting takes place in an environment where temperature, aeration and humidity are closely monitored and controlled. The percentage of biodegradability is obtained by determining the percentage of carbon in the test substance that is converted to CO2 during the duration of the test.
Gas Endeavour® can be configured for measuring the evolved carbon dioxide by coupling with our ex-situ carbon dioxide absorption kit. In such configuration, the analysis of each test material will need two measuring lines in order to calculate the evolved carbon dioxide. The instrument allows for continuous and on-line monitoring of carbon dioxide evolution according to a modified system configuration for simulating aerobic composting conditions.
