Biodegradation rate of aerobic composting test

After mixing the sample material and the compost inoculum, put it into a composting container and fully compost it under certain conditions of oxygen, temperature (58±2C), and humidity (50-55%), and measure the material degradation 45 days later The final release of CO2 (which can be extended to 6 months), the ratio of the actual CO2 release to the theoretical maximum release is used to express the biodegradation rate of the material. The test reference is cellulose with a particle size of less than 20μm, and the test is valid only when the degradation rate of the reference is greater than 70% after 45 days.
