Project Description

Asia Materials Laboratory needed for ASTM Testing to ASTM 6954 - Standard Guide for Exposing and Testing Plastics that Degrade in the Environment by a Combination of Oxidation and Biodegradation comprises three Tiers of testing; oxidation, biodegradation and ecotoxicity. Tier 1- The determination of molecular weight (MW) of HDPE containing ReverteT exposed to a combination of UV and elevated temperature demonstrates that ReverteT for High Density Polyethylene significantly accelerates the rate of oxidation, Tier 2 - The degree of biodegradation is determined using the oxidised material compliant with Tier 1. The oxidised HDPE material, above, has been shown to mineralise under aerobic conditions when tested to ASTM D5338-98 Standard Test Method for Determining Aerobic Biodegradation of Plastics Materials Under Controlled Composting Conditions., Tier 3 - Residue from the above ASTM D6954-04 Tier 2 biodegradation testing was tested for eco-toxicity with regards to the Tier 3 requirements of ASTM D6954-04.
