Thousands of Streatham and West Norwood homes are being encouraged to recycle their food waste as part of a green scheme being extended to the areas.
Residents have been handed special kitchen equipment to separate food waste and kitchen scraps for recycling - so they do not end up in landfill sites.
Some 1,500 houses in Streatham, around the Gracefield Gardens and Sunnyfield Road area, and 1,500 in West Norwood, have been given a kitchen caddy, outdoor caddy, and starch liners that allow them to separate out all cooked and uncooked food waste.
The waste will be collected by the council on a weekly basis and turned into compost to be used by farmers in south east England, avoiding the need for artificial fertilisers.
The extra homes have been added to a food waste trial covering 8,000 homes in Lambeth last July.
Lambeth Council has said the trial had proved a success.
Some 60 per cent of homes are regularly using the service, with homes in Streatham and Thornton wards the top performers, with 73 per cent of residents taking part.
Councillor Sally Prentice, Lambeth's cabinet member for environment, said: “Food waste is a major contributor of greenhouse gases if it is sent to landfill, so this is an important new service."
