The standard defines the requirements to be met by plastic items that can be disposed of through composting household, also called cold composting, that is through aerobic biodegradation at room temperature. The term: ambient temperature, is intended to indicate the temperature range of temperate regions, excluding the high temperatures typical of industrial composting. The standards takes into account the biodegradable materials at room temperature according to UNI 11183 and establishes criteria for items that made with these materials, are compostable in home composting systems. In the standard the requirements of biodegradation and ecotoxicity are not taken into consideration as such these requirements are already covered by UNI 11183 in reference to plastic materials as based materials for the manufacturing of the items.
