continued Another energy-efficiency feature is the plant’s equipment recaptures the waste heat from burning fuel and reuses it to “enhance the digestion process” and provide heat to two buildings. The entire process also reduces odors and results in a finished product that can be used for compost, according to NYSERDA.
The facility dates back to the early 1900s and was still using equipment that was more than 50 years old before the rehabilitation project. Additional upgrades at the facility include new technology that reduces the water content of sludge before processing, new equipment to insulate and seal the anaerobic chamber and equipment to remove acidic hydrogen sulfide from the biogas to protect equipment from corrosion.
A U.S. Department of Energy grant of $600,000 also helped fund the project as well as a general energy-efficiency study for the city.
