Controversial plans have been submitted to expand a rubbish facility which converts gas into electricity to power the National Grid.
Quercia Limited run a revolutionary project at their Clayton Hall Landfill Site in Clayton-le-Woods, between Chorley and Leyland.
It powers up to 700 homes across the country by using methane gas generated on site and turns it into electricity.
The scheme has been so successful that bosses at Neales Waste Management, who run the site, want to install another small engine to increase the output.
They have submitted an application to Chorley Council for there are concerns among residents who have had problems in the past with smells from the site.
Sharon Close, 61, who lives on nearby Glenmore Close, has been one of those to complain,
She said: “During the summer, you had to keep your windows shut because of the smell.
“At least they are re-using the gas for energy which we are all able to use.”
She believes with noise from another engine could impact on residents living in Spring Meadow.
Clayton Hall is using the innovative renewable energy source creates green electricity and will cut annually carbon emissions by the equivalent of around 30,000 tonnes - the same as three million trees.
A spokesman for Neales Waste Management said: “We are very aware of the residents concerns about noise of the gas generation scheme. Noise consultants have been employed to look into the proposals even at night the additional engine would not cause any more noise to local residents.”
