Bison Renewable Energy Under Construction

Bison Renewable Energy is a Minneapolis based company that is building a bio-gas regional anaerobic digester or “BRAD”.   The project is called the Cornerstone BRAD as it is the first of its kind in the U.S. and one of the largest in the world.   The project is expected to be completed this fall and will take animal and organic waste such as animal fat and convert it to methane gas.
