III. Product Principle

This experimental system simulates the biodegradation of bio-based materials under aerobic composting conditions. In an aerobic environment, microorganisms utilize the bio-based material as a carbon source, consume oxygen, and produce inorganic compounds such as carbon dioxide and water. The concentration of carbon dioxide is monitored in real time using a high-precision infrared sensor, and by integrating the measured CO₂ concentration with flow rate and time, the total amount of CO₂ released during the sample’s biodegradation can be calculated. The ratio of the experimentally determined CO₂ release to the theoretical CO₂ release serves as the biodegradation rate.
