PSE&G (NJ) Generates Heat from Sewage in Camden, NJ
PSE&G is using the thermal energy from a sewage plant in Camden, NJ to help heat the facility. The system is closed loop – meaning the sewage does not enter the building – but the heat energy is extracted and used to offset the need for electric to heat the facility.
The “ … $1.3 million project … is one of 18 funded by PSE&G toward meeting a state requirement that utilities invest in improving energy efficiency …”
“ … project is believed to be the first of its kind in the United State …”
The waste heat system is expected to save “ … $80,000 a year on electricity bills, about a quarter of its heating costs.”
In addition to the energy / electric savings there is a positive environmental impact.
