Scope

This part of GB/T 19277 specifies a test method for determining the discharge of a material under controlled composting conditions.
The amount of carbon dioxide is used to determine its ultimate aerobic biodegradability. This method regulates the humidity, aerobic concentration and temperature in the compost container
Equal conditions to achieve the best rate of biodegradation.
This section applies to the following materials.
--- natural and/or synthetic polymers, copolymers and mixtures thereof;
---Plastics containing additives such as plasticizers and pigments;
---Water soluble polymer;
--- Materials that do not inhibit microbial activity in the inoculum under the experimental conditions.
If the test material has an inhibitory effect on the microorganisms in the inoculum, other types of compost compost or pre-exposure compost can be used.
