RECYCLING
Recycling is often used as an objection to making plastic degradable, but this is not a well-founded objection, for the reasons given at https://www.biodeg.org/subjects-of-interest/recycling-2/
Recycling does not however address the principal concern about plastics around the world – how to deal with the plastic which has escaped into the oceans and elsewhere in the open environment from which it cannot realistically be collected, and therefore accumulates every day for many decades.
It is obvious that you cannot recycle plastic unless it has been collected.
Symphony Environmental Technologies plc (LON:SYM) is a world leader in the development of additives to make ordinary plastic biodegradable and protective technologies to enhance plastic products.
