Three, Product Principle

This experimental system can simulate the biodegradation process of bio-based materials under aerobic composting conditions. In an aerobic environment, microorganisms metabolize the bio-based materials as a carbon source, consuming oxygen and producing inorganic byproducts such as carbon dioxide and water. The generated carbon dioxide is immediately absorbed by the alkaline substance contained in the absorption bottle. After the automatic weighing procedure is initiated, a robotic arm drives a mirror-polished stainless steel platform downward, causing the absorption bottle to naturally rest on the weighing sensor. The sensor then collects weight data and transmits it in real time to the PLC controller. Once the weighing is complete, the robotic arm lifts the absorption bottle upward, completely disengaging it from the weighing sensor. After a preset time interval, the system automatically starts the next round of weighing. By continuously monitoring the weight of the absorption bottle via the automatic weighing unit, the incremental weight gain represents the amount of carbon dioxide released during the sample’s biodegradation. The percentage of the sample’s actual carbon dioxide release relative to its theoretical carbon dioxide release constitutes the biodegradation rate.
