Introducing the Compost Degradation Tester GBDA-180W: Unlocking Precise Biodegradability Analysis

Overview The Compost Degradation Tester GBDA-180W employs the gravimetric method, a professional approach utilising small reactors to gauge carbon dioxide emissions. Tailored for determining the ultimate biodegradability of various test materials, it excels in analysing degradable plastics and bio-based materials such as lunch box garbage, waste ground film, plastics with plasticisers, and pigment additives.

Executive Standard In adherence to industry benchmarks, GB/T19277.2-2013 and ISO 14855-2:2007, the GBDA-180W sets a high standard for precise biodegradability testing.

Testing Principle The test material combines inoculum of decomposed compost with inert materials, creating an environment conducive to biodegradation. Controlled parameters such as humidity, oxygen permeability, and temperature drive the microorganism-mediated reaction. Oxygen is transformed into carbon dioxide, discharged through respiration, and quantified using a gravimetric method with an absorption device equipped with soda lime and sodium talc. Regular measurements yield accurate decomposition rates.
