Landfill gas-to-power generation contributes to increased reliability of the local power grid

Biogas Project of the Year

Monogram Snacks has leftover oils and fats that need disposal. To avoid incurring high monthly surcharges for processing wastewater, Monogram built a new clean energy plant. An anaerobic digester breaks down the waste and converts it to methane gas, which is used to fuel a Cat® CG132-08 gas genset, saving on their utility bill. Monogram Foods was recently recognized as the “Biogas Project of the Year” by the American Biogas Council. The Biogas Project of the Year honors an operation that strongly exemplifies financial ingenuity, energy efficiency and sustainable waste treatment.
