Aerobic biodegradability of plastic materials under controlled mesophilic composting conditions

ASTM D5929-18 test method determines the biodegradation properties of a material by reproducibly exposing materials to conditions typical of source-separated organic municipal solid waste (MSW) composting. A material is composted under controlled conditions using a synthetic compost matrix and determining the acclimation time, cumulative oxygen uptake, cumulative carbon dioxide production, and percent of theoretical biodegradation over the period of the test. Since the temperature can affect the biodegradation of some materials, this test is not intended to replicate conditions within municipal compost operations that reach thermophilic temperatures. 

BPC Blue can be easily coupled with our patented in-situ carbon dioxide absorption kit to function as a fully automated closed-respirometer for continuous and on-line measurement of oxygen consumption or depletion caused by aerobic respiration of microorganisms. The apparatus is suitable for all test protocols which the measurement principle can be based on respirometry or oxygen demand (BOD) measurement.
