      The anaerobic digester process produces gas, fertilizer, and construction materials, with approximately 95% of the finished solids being beneficially reused.

      • The anaerobic digestion process simulates the human stomach, transforming waste into various materials.
      • Gas produced is primarily used for heating and powering homes in Brooklyn.
      • The process also generates fertilizer and materials for landfill capping and construction infill.
      • A key point is the significant water weight in food waste, leaving 22% of digestate as solid.
      • Of these finished solids, about 95% are beneficially reused.
