I'm looking to make kids toys from United States recycling products since they are being moved to landfills. Almost no progress so far, my 400 level polymer chemistry book only has 2 paragraphs on recycling.

So far I'm trying to figure out mechanical solutions. Thinking lots of boxes so kids can make forts.

Hard website to use, unfortunate.
