Plastic recycling is a joke. If you look at the recycling they actually did, it was only a few smallish projects like plastic planks for walkways and benches, and plastic carts and shelved for some Woolworths branches to put at front of store with a label to greenwash the problem. Hooray, now those plastic walkways and benches will slowly deteriorate microplastics into the environment around them under full force of the sun and rain.
The only real solution is banning single use plastics and moving back to glass and cans - focus on things that actually are recyclable and get rid of all the plastic.
Will it be hard and more expensive? Yes. Is it worth it and will reduce long term cost of pollution cleanup? Also yes.
P. S. I am not saying that people who try to break their recycling down to recycle plastics are any part of the problem by the way - they're just trying to do their best effort in the system they've found themselves in. The system itself is a joke
