Scope: What is ISO 17556 - Aerobic biodegradability of plastic materials in soil about? ISO 17556 is an International Standard that discusses plastics. The main aim of ISO 17556 is to provide best industry test methods that demonstrate whether plastic materials are safe with regards to its impact on the environment. ISO 17556 s pecifies 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 take place in a natural environment; if a pre-exposed soil is used, the method can be used to investigate the potential 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 Note: It does not necessarily apply to materials which, under the test conditions, inhibit the activity of the microorganisms present in the soil. Inhibitory effects can be measured using an inhibition control or by another suitable method. If the test material inhibits ...
