Campaigners against plans to build a so-called incinerator for the area's rubbish will stage a protest this week.
Members of Stop the Incinerator are travelling to Kent to protest outside the head office of Viridor - the company planning to build a controversial Energy Recovery Facility (ERF) in Beddington - on Friday.
The protesters will carry placards and plan to chant "air pollution is not the solution" as they voice their objections to the company's plans.
Viridor has submitted plans to build the facility on the site of the refuse tip in Beddington Lane. The South London Waster Partnership, made up of Sutton, Croydon, Merton and Kingston, has backed the company to build the facility which would be used to dispose of the four boroughs' household waste and convert it into energy to supply to nearby houses.
But opponents say the project will cause pollution in the area and could cut recycling rates.
Paul Pickering, chairman of the Stop the Incinerator campaign, said: "These solutions are widely regarded as being harmful to human health, and result in falling recycling levels because once the contract is signed the incinerator will need to be fed 300,000 tonnes of waste for the next 25 years.
"Viridor can manage the waste in the four boroughs in a more sustainable way. They could build small scale recycling centres across the four boroughs, thus nullifying the need to build an incinerator and creating ten times more jobs in the process."
The protesters will deliver a letter to Viridor asking if its workers would be happy living near the facility.
Stop the Incinerator is screening a film called Trashed at Fairfield Halls in Croydon from 7pm on Friday, March 8. The film, which stars and is narrated by Jeremy Irons, is a documentary which explores some of the dangers the group thinks the ERF could present as well as other issues.
