And evaluation criteria " determine, European standard EN 13432 is also used in Italy (as UNI EN 13432) recently.According to this
Standard, the characteristic that compostable materials must be presented are as follows:
Biological degradability, i.e. compostable materials metabolic conversion is at carbon dioxide.Utilize test method (the i.e. prEN 14046 of standard
(be also disclosed as ISO 14855: the biological degradability under controlled composting conditions)) measure the property.Acceptance criteria is
90% biological degradability is realized in 6 months (about cellulose).
Disintegrability, i.e., fragment and visibility in final compost (without visual pollution) are lost.Utilize pilot-scale
Compost test (prEN 14045) measure the property.The sample being made of test material in 3 months with debirs one
It rises and compost is made.Finally, sieving compost using the sieve of 2 mm.The residue with the size greater than 2 mm of test material
Quality be necessarily less than the 10% of initial mass.
Composting process is not adversely influenced, verifies the property using the compost test of pilot-scale.
Low heavy metal horizontal (being lower than scheduled maximum value) and the quality of compost is not adversely influenced (for example, subtracting
Small Agronomic Value, and exist on the influence of the ecotoxicological of plant growth).Plant growth is executed to compost sample and tests (modification
Test OECD 208), wherein test material is degraded.Compared with controlling compost, it is necessary to difference do not occur.
Necessary constant other chemical-physical parameters after the degradation for the material studied: pH；Salt content；Volatility
Solid；N；P；Mg；K.
