The facility was commissioned (began operations) in 1971, by the
Greater London Council. The building is of metal sheet
clad construction with a
reinforced concrete chimney. The incinerator was Britain's largest, handling unrecycled waste from seven
London Boroughs:
Barnet,
Camden,
Enfield,
Islington,
Hackney,
Haringey, and
Waltham Forest. The
waste is converted into
carbon dioxide,
bottom ash, air pollution control residue, and other flue gases. 55
megawatts (MW) of electricity are generated, sufficient power to meet the needs of 24,000 households. In January 2021,
Taylor Woodrow Construction started work on an expansion of the facility known as "EcoPark South": the new plant, with a capacity to recover 135,000 tonnes of material each year, was due to be completed in 2023. The resource recovery facility and an EcoPark visitor centre were completed on budget, but costs on a larger contract for an energy recovery facility rose from £1.2bn to £1.5bn, due to construction material and wage inflation. Completion of the project by
Acciona, originally scheduled for 2025, was delayed to 2027. ==Environmental impact and protests==
