Petroleum waste is a major threat to the environment, I have personally seen the damage it can cause and many oil refining companies do not properly store the waste. Papusha seems like a great solution to this threat, the idea that they raise funds through an ICO leaves evidence of the many uses and benefits that blockchain can bring to people.

Excellent article, thank you very much for touching on this importan topic and how it is fought with the help of blockchain technology.
