PwC uses recycled cooking oil to power offices
PwC is to use recycled chip fat to generate power for its new headquarters on London's Southbank.
A deal has been signed which will see the firm supplied with 45,000 litres of cooking oil per month from city centre restaurants, which once refined will be used in the tri-generation facility on-site at More London.
The generators powered by the oil should produce sufficient energy to meet 25 percent of the building's electricity needs and 20 percent of heating and cooling demand.
Overall, 50 percent of the energy used by the building, which has been granted a BREEAM Outstanding rating, will be from low or zero carbon sources.
Working with ARAMARK and Arrow Oil, agreements have been signed to collect used oil from pub group Fullers, Zizi's Italian restaurants and the Corney and Barrow wine bar chain.
Jon Barnes, head of building and facilities services at PwC said: "Securing the supply within the M25 was essential, as otherwise the carbon footprint for moving the oil increases and would have defeated the purpose of investing in the low carbon technology."
More London was the first building in the capital to receive an outstanding rating, offering a 70 percent improvement in energy performance on an A rating Energy Performance Certificate.
