Residents of Merseyside can recycle used cooking oil after collection tanks were fitted at 14 household waste recycling centres across the region.
Merseyside Waste Disposal Authority and contractor Veolia Environmental Services have teamed up with green energy firm Living Fuels for the scheme.
Living Fuels will collect the waste oil and refine it through a natural process to produce a patented bioliquid that will power specially-designed engines to supply electricity to the National Grid.
Water companies in the UK spend an estimated £15m a year clearing used cooking oil from their sewers and 75% of the 200,000 drain clearance call outs involve used cooking oil.
MWDA chair councillor Joe De’Asha said: “As well as removing this waste product from the environment we’re also helping to create energy so residents can be doubly pleased they’re helping clean up Merseyside.”
