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.
