Biowrap

THE SCIENCE BEHIND BIOWRAP Continued The BMP (Biochemical-Methane Potential) lab test data is used internationally by governments, universities and commercial operators to determine the true biochemical methane potential and dynamic degradation profile of a material in anaerobic conditions. The test validates our landfill-biodegradable plastic can be digested by microorganisms within an environment with no/limited oxygen and limited light. There is no toxic residue when the biodegradable plastic decomposes. Plastics such as polyethylene break down to methane (CH4), carbon dioxide (C02), and organic matter (humus). Extracellular Enzymes Water Soluble Intermediates Short degradation intermediates are dissolved into the medium Intermediates are assimilated into the cells Other metabolic products C0 2 H 2 0 CH 4 Surface Erosion Excretion of extracellular enzymes Enzymes attach to the surface and cleave polymer chains MICROORGANISM PLASTICS CH 4 CH 4 CH 4 CH 4 H 2 0 C C OH O O O This diagram illustrates the additive and the landfill-biodegradable process: We have ASTM and BMP tests, which are recognised internationally as being the benchmark of verifications. The ASTM D5511 is a test performed by an independent laboratory that measures the carbon released from the plastic as a biogas to verify claims of biodegradability in anaerobic conditions, intending to replicate conditions found in a typical landfill.
