This is a very good idea - the release of tens of thousands of hectares of irretrievably lost areas under waste dumps. I like efficient closed-type waste-free production. But how will blockchain help in the extraction and production of useful materials from waste, in particular precious metals?
I think blockchain is not very important here. As I understand it, the guys use ICO to collect investors ' money, because they can not get a Bank loan. This is a common situation for Russia. The government doesn't like manufacturing here...
