That's a very good question. I've done a lot of research into the whole business in this plant. I think we need to step back a few places about the business in general.
The plant is to be built and managed by GEP and Energy Indiana. GEP are responsible for finding funding. The entire business is a JV with IGE: Integrated Green Partners LLC (IGP).
The backend core of the business is procuring the plastics, and shipping into the site. This is business category "waste management".
In America business operates on many levels. Waste Management in America is an UNREGULATED business excluding hazardous materials and Nuclear waste.
It's important then to note who's who in US waste management. This link may or may not be relative but I recommend you read:
https://people.howstuffworks.com/10-businesses-supposedly-controlled-by-the-mafia1.htmThe construction was poleaxed for 3 years because a legal stouch emerged on the rail link to the US hub. It was originally US RAILCORP. It's now W&G. Neither funding or construction could commence without the rail link to ship in the waste plastic. The stouch was settled in Nov 2018.
Tangier was established in early 2019 and appear to have no other business (that I can find). They were nominated as the funding manager by IGE Jan 15 2010. Given GEP were responsible for funding they must have come from GEP. Tangier have a rented office space and the directors appear untraceable, by my research. My take is that Tangier would have appeared through the need of procurement of the waste (waste management) and have also now provided funding with a seat on the board (IGP) and 3.5% interest repayments. Tangier are under no legal obligation to provide info on where they source funding. GEP are under no legal obligation to divulge where or how they are sourcing the waste, but to do so they must engage with established organizations. It's how it's done in America. imo. I have no opinion as to whether the above has occurred, but I personally think Tangier has the money. imo.
