Fitting, I just started looking into reusing plastic myself by collecting plastic from my own, family and friends trash and remoulding it into something useful. In my quest for this, I found Precious Plastic, an amazing community around recycling plastics yourself and for your community. https://preciousplastic.com/
While individuals plastic pollution is not the biggest emitter of plastic here in the world, we can always take small steps towards making sure we don't throw as much plastic as we currently do.
- And the most helpful, PPs Discord community, tons of channels and even more people, usually very responsive and very diverse - https://discordapp.com/invite/cGZ5hKP
I've only run smaller experiments so far, mostly focusing around storage containers as I have a lot of electronic stuff that is currently just laying around. You can get some more inspiration here of what you could mould: https://bazar.preciousplastic.com/moulds/
But in general, anything you've seen in the real world would be possible to recreate with your own moulds, the limit is your imagination!
