Whilst this is a great idea and an admirable challenge youve set for yourself, I think Youre best off going along the more traditional ways of raising money.
If you area a registered charity, companies can get tax breaks/exemptions for donating to your cause. Accepting donations in FIAT also gives you a greater pool of donators/investors (although investing will depend on whether youre a for-profit organisation, NGO/Charity or social enterprise).
This will have to be a for profit venture otherwise i can't expand it and take it further, fortunately electricity ain't cheap around here so there is good margins. Just worried traditional investors would eat away at most the profits in return for funds hence i was considering crypto funding. But you may be right
I would suggest doing some research on using superworms to eat styrofoam. Apparently they subsist on it happily and consume it very fast. I don't know if the worms are then toxic or what, but this seems like an area worthy of research within a smaller budget.
unfortunately it don't sound like the worms would be profitable, as much as i'm doing it for the eco reasons, unless its profitable it wont make a dent in reducing waste as i cant expand it further
