They also use: wind power, cogeneration through a heat exchanger, a multi-stage compressor unit for refrigeration.

In this video, the brewery’s operations engineer Ron DeWitt talked to faircompanies tech advisor Erik Frye about their energy generation and what their recycling efforts, both of spent grain and yeast and secondhand manufacturing equipment.
