Compost Degradation plastics test equipment

Product introduction

GBDA-180W The Compost Degradation Tester is based on the gravimetric method for

measuring carbon dioxide emissions. It is a professional use of small reactors to determine
the final biodegradability of test materials. It is suitable for the biodegradability
analysis of degradable plastics and bio-based materials such as lunch box garbage, waste
ground film,

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.
