Making Plastic Smarter

Biodegradable Products


These bags are biodegradable on land and in water, and are designed to reduce the impact of plastic as litter. Timeframe for degradation depends upon environmental conditions and requires oxygen to be present. The degradation process can take several years. When disposed of in landfill, Eco-pal bags are unlikely to degrade – but degradation is possible. If degradation occurs it will take significantly longer than if the bag is in the open environment. If degradation occurs, it is followed by biodegradation and no harmful chemicals remain. These products are not suitable for composting

Why degradable?

All plastic will in time fragment and completely biodegrade, but it could take many decades. Symphony's d2w controls the process, and turns the 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, and the fragments can be bio-assimilated in the open environment faster than straw and twigs and much faster than ordinary or recycled plastic. d2w has passed the usual eco-toxicity tests and does not contain "heavy-metals." It is certified for direct food-contact.

Go into any supermarket and what do you see? - Plastic.

Not just carrier-bags, but almost everything is wrapped or bottled in plastic - from frozen peas to fresh potatoes - from sandwiches to milk - beer cans to newspapers, televisions and even ironing boards. At the back of store there are acres of shrink-wrap, pallet-wrap and bubble-wrap used to deliver goods in bulk.


Because plastic is in most cases the best and most cost-effective way to protect goods from damage, contamination and wastage.

So why are people concerned about plastic?

Is it because plastic is made from oil or natural gas, or coal which are finite resources? 
But this is a mistake, because it is actually made from a by-product of the refining process which will always be produced so long as the world needs this type of fuel, and it makes good economic and environmental sense to use the by-product instead of wasting it and using scarce land and water resources to grow crops to make plastic.

Because it is symptomatic of a "throw-away" society? 

Well - life moves at a much faster pace whether we like it or not. We can no longer buy milk in a jug from the corner shop, and packaging has adapted to modern life. Of course we must dispose of plastic responsibly, however we will never collect it all, and some will inevitably find its way into the open environment, where it could lie or float around for decades.

This is the real problem - to which Symphony is supplying the solution in more than  90 countries worldwide. Symphony has developed a formulation called "d2w" which is added to normal plastic at the manufacturing stage, and makes the plastic degrade at the end of its service life, by a process of oxo-biodegradation, leaving no harmful residues. We call it "Controlled-life" or "Intelligent" plastic - (for a video of d2w plastic degrading see d2w plastic bag degrading).

Plastic made with d2w costs very little extra, because it is made with the same machinery as normal plastic, and it causes no loss of jobs in the plastics industry. There is no need to change suppliers, but Symphony can supply finished-products if required. OXO Biodegradable Infographic OXO Biodegradable Infographic
