Product principle

This experiment system simulates the process of biodegradation of bio-based materials under aerobic composting conditions. In the aerobic environment, microorganisms consume oxygen and produce carbon dioxide, water and other inorganic substances with bio-based materials as the carbon source. The generated carbon dioxide is monitored in real time by high-precision infrared sensors, and the real-time concentration of detected carbon dioxide is integrated with the flow rate and time to calculate the carbon dioxide release from the 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.

Examples of experiments

This is the experimental result of testing the biodegradability of a sample by using the M9000 compost infrared biodegrader and referring to the method standard GB/T19277.1-2011. The test period was 70 days. As can be seen from Figure 1, the degradation rate of cellulose reached 81.88% within 45 days. Within 70 days, the degradation rate of cellulose reached 98.18%. At this time, the growth of each experimental group basically ended, and the curve was smooth. The experimental design was shown in the following table:
