COMPOSTABLE
The right to use the mark of conformity "COMPOSTABLE" on compostable plastic bags and on compostable products is granted only to those manufacturer/distributors that demonstrate that their product conforms with specific performance attributes and adheres to the parameters for "compostability" as set out in the BNQ documents, Compostable Plastic Bags - Certification Program
(BNQ 9011-911/2007) and Compostable Products – Certification Program (CAN/BNQ 0017-988).
It is important to be aware that "compostable" and "biodegradable" are not equivalent. Similarly, "disintegration" cannot be used interchangeably with either of these terms.
The definitions established for the purpose of the program are as follows:
Biodegradation: degradation caused by biological activity especially caused by enzymatic action leading to a significant change in the chemical structure of a material. (Reference: ISO 162929, section 3.3)
Compostable: said of that which is capable of undergoing biological decomposition in a compost site such that the material is not visually distinguishable and breaks down into carbon dioxide, water, inorganic compounds and biomass at a rate consistent with known compostable materials. (Reference: ASTM D 6002) . |
