When I was a builder we used to pour a concrete ring foundation with reinforcing steel in it and then fill up the center of the ring with river stone and compact it. Then we would pour a 100mm (4inch) thick slab on top with reinforcing mesh in it. Is there any reason the hard fill under the concrete couldn’t be recycled plastic chips the size of stones? (Same with under road surfaces). I feel like this would solve our plastic waste problem.

Hint. Any plastic that has been in contact with oil food, greases, and it’s smeared with anything that sticks to it, turns it into a unrecyclable thing. No matter how much you wash it, it will have something ELSE that make it worse or impossible to reuse.
Most of our thrash ends up so dirty it doesn’t makes any sense to recycle it. Like 90% or more.
Aluminum has to be molten back and most stuff ends up burned on the heat. The rest floats over the alu, and it’s just removed. Alu is soon much better to recycle. Same as glass. Need so much temp.
