PLASTICS, DESIGN & MOULDING PLASTIC AWARE SYMPHONY THINGS YOU MIGHT NOT KNOW ABOUT OXO-BIODEGRADABLE PLASTICS 1 - THEY DON’T JUST FRAGMENT INTO HARMFUL MICROPLASTICS   One long-perpetuated myth is that oxo- biodegradable plastics break down into smaller plastic fragments which are still harmful to the natural environment. While microbeads and microplastics are a real issue, they are not the end-product of oxo- biodegradation. d2w rapidly accelerates the degradation process beyond microplastics, the molecular weight decreases to a point where it is no longer a plastic and is available as a food source to microorganisms in the environment, in the same way as nature’s waste. This leaves behind a substance called 162 PECM Issue 38 humus (not the chickpea dip, but the organic material found in soil).   2 - REDUCE, REUSE, RECYCLE STILL APPLIES   It’s a noble attempt to try and eradicate plastic waste from the natural environment – and reducing, reusing and recycling is a very simple and effective step towards this. But let’s be realistic – some plastic is always going to escape the process and end up in our oceans. We need a strategy for this eventuality and oxo-biodegradable plastics could be a piece of the puzzle. Plastics that escape into the natural environment that would otherwise linger and cause harm to wildlife can instead be reduced to a small amount of harmless organic matter.   Oxo-biodegradable products are designed to be reused. With oxo-biodegradable technology, the plastic will only start degrading when exposed in the environment as litter, meaning you can reuse your plastic bags several times. Finally, d2w does not affect recyclability, in fact more than 500,000 tonnes of oxo- biodegradable plastic has been recycled in the last 5 years[1]. So please dispose of your oxo-biodegradable plastic products responsibly and recycle with your other plastic products.
