Scope

This standard specifies procedures and requirements for the identification and identification of plastics and products with aerobic composting performance.
The technical requirements of this standard include the following four aspects.
a) biodegradability;
b) disintegration performance;
c) negative impacts on composting processes and equipment;
d) The quality of the resulting compost, including the amount of controlled metals and other harmful components.
This standard also specifies the identification content of compostable plastics and products, such as “compostable” or “compostable in municipal or commercial facilities” or “heap”
Biodegradable in the process of fertilizer."
Note. Composting of compostable plastics should be carried out in well-run composting facilities, requiring suitable temperature, water content, aerobic conditions, carbon/nitrogen ratio
And processing methods, etc. Commercial and municipal composting equipment can usually meet these conditions. Under these conditions, compostable plastics will disintegrate and biological
Decomposition, the decomposition rate is equivalent to garden waste, kraft paper bags and food debris.
