ISO 15985:2004规定了一种在高固体分厌氧消化条件下，通过测量发酵的沼气和试验结束时的分解程度，评估基于有机化合物的塑料最终厌氧生物降解性的方法。该方法旨在模拟混合城市固体废物有机部分的典型厌氧消化条件。在实验室试验中，将试验材料暴露于产甲烷接种物中，该接种物来自仅对预处理的生活垃圾进行操作的厌氧消化池。厌氧分解发生在高固体（总固体含量超过20%）和静态非混合条件下。试验方法旨在测定试验材料中碳的百分比及其转化为二氧化碳和甲烷（沼气）的速率。

ISO 15985:2004 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).
