What is d2w (biodegradable plastic)?
d2w is the brand for controlled-life plastic technology which is designed to control and shorten the life of normal plastic products and packaging. d2w is a carefully researched and tested additive formulation which is added to normal plastic at the extrusion or casting stage of manufacture.
Symphony’s d2w formulation is so effective that it needs normally to be included at only 1%, resulting in considerable savings in cost, transport, and storage.
PE and PP are hydrocarbons, and their molecular backbones are constructed of hydrogen atoms bonded together by carbon atoms in long entangled chains. It is these long chains that provide flexibility, strength and significantly prevent oxygen from attaching to the carbon and hydrogen atoms and causing oxidation; which in turn leads to degradation.
A no-change added-value solution
No need to change designs or suppliers – just add d2w!
D2w converts ordinary plastic at the end of its useful life into a material with a completely different molecular structure. At that stage it is no longer a plastic but has become a material which can be bio-assimilated in the environment in the same way as a leaf.
Heat, light and stress accelerate the process – but are not essential.
d2w plastics are not currently marketed as compostable, nor are they intended to degrade under anaerobic conditions in landfill.
They can be recycled with other oil-based plastics – unlike “compostable” plastics, which will ruin a normal plastic recycling process.
Why choose d2w Controlled-life Plastic?
Normal plastic d2w Controlled-life Plastic Technology
Used throughout industry. Tested and proven safe for food, medical, farming and many other applications
Can be re-used
Will eventually degrade to CO2 and H2O but can take many decades
Will not meet any degradability or biodegradability standards
Can be recycled, though stabilisers will normally be required to replace properties lost during the recycling process
Made from a by-product of oil, so nobody is importing extra oil to make it d2w improves the excellent properties of normal plastic by controlling and reducing its lifespan and therefore making it more acceptable
Can be re-used and recycled in the same way as normal plastic.
