Product principle
Bio-based materials, under the action of microorganisms, consume oxygen to decompose and produce carbon dioxide, water and other inorganic substances. The generated carbon dioxide is monitored in real time by high-precision infrared sensors. The percentage of the actual carbon dioxide release of the sample and the theoretical carbon dioxide release of the sample is the biodegradation rate.
