The capability of the compostable material to be converted into CO2 under the action of micro-organisms. This property is measured with a laboratory standard test method: the EN 14046 (also published as ISO 14855: biodegradability under controlled composting conditions). In order to show complete biodegradability, a biodegradation level of at least 90% must be reached in less than 6 months. The norm EN 13432 is an harmonised norm. That is, it has been quoted in the Official Journal of the European Union, it has been implemented in Europe at a national level, and it provides the presumption of conformity with the European Directive 94/62 EC on packaging and packaging waste.
