Testing Principle
The test material of this method is a mixture of inoculum of decomposed compost and inert materials (such as sea sand and vermiculite). By controlling the humidity, oxygen permeability and temperature of the compost container, the sample to be analyzed in the reaction chamber is under the action of microorganisms. The biodegradation reaction is carried out through respiration, and oxygen becomes carbon dioxide and is discharged through respiration. The amount of carbon dioxide released is measured by weighing the absorption device equipped with soda lime and sodium talc, and the decomposition rate is calculated by regular measurement.
