I have long argued that bitcoin mining not only uses a completely inconsequential amount of electricity in the wider scheme of things, but also uses a much higher proportion of renewable electricity than almost any other sector and is actively beneficial in the development of new renewable infrastructure.

But, here's my question to you as a biological scientist about your proposal: What is stopping the development and building of these bio-degradation plants right now? If they can reduce waste while producing usable energy or electricity which can be sold at a profit, then why do we not have more of them already? Why would sticking a bitcoin mining operation on the side make any difference?
