Recycling is not the solution
If we want a more sustainable planet and less pollution, recycling is not what we need. What you will say, why? Because it leads to a false promise. It sounds like once used, objects can turn back in the circle, can turn back into nature, but this is false.
PVC, PU or any other plastic is made of raw oil and no matter what you do, once it is plastic it will never biodegrade.
Lower and more responsible consumption
The only solution is to consume less. To already inject less things in the world, to say no to plastic bags and choose carefully when purchasing. Select materials which are possible to biodegrade and there will be much less pollution.
