My work is connected to plastics recycling. It does happen, but what's useful for recycling is pure truckloads of all the same type and color of plastic.
Which means mostly post-industrial waste: the leftovers from a manufacturing plant. Or you can do stuff like collect all the clear stretch-wrap from retail shipping and compress that and recycle it.
But post-consumer is hard because it tends to be many different kinds mixed together. Sorting them all out is necessary and expensive.
