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
( and Compostable Products – Certification Program （和堆肥产品 - 认证计划。
It is important to be aware that "compostable" and "biodegradable" are not equivalent. Similarly, "disintegration" cannot be used interchangeably with either of these terms.
要知道，“可堆肥”和“可生物降解”是不等价是重要的。同样的，“崩解”不能互换使用任一这些条款。 The definitions established for the purpose of the program are as follows:
建立了该程序的目的的定义如下 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)
生物降解性：所造成的特别是由酶作用导致在材料中的化学结构的显著变化引起的生物学活性降解。 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) .
