We use Symphony Environmental’s pro-degradant D2W in our products and also EPI-Globals TDPA. The former is a UK company and the latter a Canadian based company. There is a big mis-conception that degradable plastic causes Micro Plastics and I urge you to watch this clip to show you how plastic containing just 1% of D2W biodegrades.
Microplastics are tiny pieces of plastic, which are being found on land, in the sea, and now even in the air we breathe. They are created by the fragmentation of ordinary plastics caused by the effects of uv light and mechanical stress. The problem is that although these plastics are fragmenting, their molecular-weight remains too high for biodegradation, so they persist in the environment, getting smaller and smaller over a period of many decades. The answer to this problem is to make the plastics in a slightly different way, with oxo-biodegradable technology, so that if they do get into the open environment the molecular-weight of the plastic will rapidly reduce and it will cease to be plastic. It will then have become a source of nutrition for micro-organisms, who recycle it naturally, back into nature. This technology is suitable for almost all products made with polyethylene, polypropylene, or polystyrene.
