Packaging and Packaging Waste – Part 7:

Recoverable by Composting and Biodegradation

1 Scope

This Part of GB/T 16716 specifies the requirements for evaluating the biodegradation and

composting of packaging and packaging materials, test schemes, verification of biodegradation,

disintegration determination and quality of composted products.

This Part applies to the evaluation of compostable packaging by enterprises that utilize waste

composting (including the production of biogas).

This Part does not apply to the decomposition of packaging waste in the natural environment

and various residues present in packaging.

NOTE: When some components of the package are not suitable for composting, if they can be separated

by a simple method, this Part can still be applied to the packaging.
