Product principle

This experiment system simulates the process of biodegradation of bio-based materials under aerobic composting conditions. Under aerobic environment, microorganisms consume oxygen and produce inorganic substances such as carbon dioxide and water by using bio-based materials as carbon sources. The generated carbon dioxide is absorbed by alkaline absorption column, and the increased weight is the carbon dioxide released by biodegradation of the sample. The biodegradation rate is the percentage of the carbon dioxide released by the sample biodegradation and its theoretical carbon dioxide release.

Typical cases

This is the experimental result of a certain unit using M9000W compost method biodegradation instrument to test the biodegradability of a sample with reference to the method standard of GB/T19277.2-2013. The test period is 50 days. It can be seen from Figure 1 that the degradation rate of cellulose has reached 79.13% within 45 days. At this time, the growth curve of each experimental group is flat and will gradually degrade completely as the experiment proceeds. The experimental design is shown in the following table:
