There is a new method to create waste backed crypto with anaerobic digestion. This is an unlimited resource. You can convert waste and sewage to electricity in these new plants and then sell the electricity with Energy Web Token (EWT). Send a private message for more details if you are interested.
It is no problem to share details about a new project but waste backed crypto looks new to me to some extent, i doubt anyone needs crypto currency to convert waste to electricity. Moreover can you provide a link to thee project ann thread? Website or Whitepaper??
