Anaerobic biodegradation of plastic materials in an aqueous system 


ISO 14853:2016 defines a method for evaluating the ultimate anaerobic biodegradability of plastics in an aqueous system by anaerobic microorganisms. In this method, a test material with desired concentration organic carbon is incubated at mesophilic condition in sealed flasks together with the pre-treated digested sludge for a period normally not exceeding 60 days. The amount of microbiologically produced biogas carbon is calculated from the net biogas production and the net inorganic carbon (IC) formation in excess of blank values. The percentage biodegradation is calculated from the total amount of carbon transformed to biogas and IC and the measured or calculated amount of carbon added as test material. 

Gas Endeavour® allows for continuous and on-line monitoring of released biogas (CH4 and CO2) under the test condition. The instrument offers standardised measurement procedures, data interpretations and reports, as well as user-friendly operation with remote access.
