d2w®Oxo-Biodegradable Plastics
Plastic is fantastic!
Plastic is strong, durable, versatile, lightweight, safe and inexpensive. It is made from a by-product of oil refining which would otherwise be wasted, so nobody is importing oil to make plastic products. However, the problem identified by governments and NGOs around the world is that plastic does last rather too long if it gets into the environment and especially in the oceans. so, why not we make plastic degradable after its safe service life?
d2w® passes the tests prescribed by
"American Standard ASTM D6954" for Plastic that Degrade in the Environment by a Combination of Oxidation and Biodegradation. Oxo-degradation of plastics is defined by TC249/WG9 of CEN (the European Standards Organisation) as "degradation identified as resulting from oxidative cleavage of macromolecules." And oxo-biodegradation as "degradation identified as resulting from oxidative and cell-mediated phenomena, either simultaneously or successively."
Now we have the solution ! "D2W® Oxo-biodegradable = Oxidation + Biodegradation
d2w®is a low cost additive for polyethylene and polypropylene which causes the plastic to break down into a biodegradable form (the long plastic chains break down into shorter chains which can then be accessed by micro organisms which break them down to carbon dioxide and water.
Degradation reactions will start soon after the product is made, but the fact that the formulation contains a stabilizing package moderates these reactions so that outward signs of degradation such as loss of mechanical integrity should not be evident. This leads to the concept of an induction period for break down and thus a useful shelf life. d2w®additive works to break down the carbon-carbon bonds in the plastic leading to a lowering of the molecular weight and eventually to a loss of strength and other properties. The plastic does not just fragment, but is consumed by micro-organisms after the additive has reduced the molecular weight to sub 40,000 Daltons , and it is therefore "biodegradable." This process continues until the material has biodegraded to nothing more than CO2, water, humus, and trace elements.
