Tip for plastic waste: One can opt for making “plastic bricks” which is a space saving method which has potential for reuse/upcycle. The problem I had with plastic waste is that we clean and collect them. But storing large amounts is a problem. So you can use PET bottles to stuff clean plastic into the bottle (see: Bottle Bricks | Engineering For Change)
I had tried this once, I could stuff 1.5 months worth of plastic in one bottle. And they are quite sturdy. The “plastic bricks” may be collected over time to design a piece of furniture (stool, chair)
