Full Description

This document specifies a method for determining the ultimate aerobic biodegradability of plastic materials in soil by measuring the oxygen demand in a closed respirometer or the amount of carbon dioxide evolved. The method is designed to yield an optimum degree of biodegradation by adjusting the humidity of the test soil.

If a non-adapted soil is used as an inoculum, the test simulates the biodegradation processes which takeplace in a natural environment; if a pre-exposed soil is used, the method can be used to investigate thepotential biodegradability of a test material.

This method applies to the following materials:
natural and/or synthetic polymers, copolymers or mixtures of these;
plastic materials which contain additives such as plasticizers or colorants;
water-soluble polymers.

It does not necessarily apply to materials which, under the test conditions, inhibit the activity of themicroorganisms present in the soil. Inhibitory effects can be measured using an inhibition control orby another suitable method. If the test material inhibits the microorganisms in the soil, a lower testmaterial concentration, another type of soil or a pre-exposed soil can be used.
