Description / Abstract:
This International Standard specifies a method for the
evaluation of the ultimate anaerobic biodegradability of plastics
based on organic compounds under high-solids anaerobic-digestion
conditions by measurement of evolved biogas and the degree of
disintegration at the end of the test. This method is designed to
simulate typical anaerobic digestion conditions for the organic
fraction of mixed municipal solid waste. The test material is
exposed in a laboratory test to a methanogenic inoculum derived
from anaerobic digesters operating only on pretreated household
waste. The anaerobic decomposition takes place under high-solids
(more than 20 % total solids) and static non-mixed conditions. The
test method is designed to yield the percentage of carbon in the
test material and its rate of conversion to evolved carbon dioxide
and methane (biogas).
The conditions described in this International Standard may not
always correspond to the optimum conditions for the maximum degree
of biodegradation to occur.
