The Biomass Storage and Pretreatment Building is 9,000 square feet and is available along with equipment to handle, dry, and grind large quantities (up to 2 tons per day) of biomass. Dry storage of 20 tons of different types of biomass is possible. The biomass grinder is located under an adjacent open-sided, covered-roof structure to minimize risk of dust explosion.

Five hammermills, a Fitzmill, and a belt dryer are available.
