More than 1,100 tonnes of food waste turned into biogas in South Kesteven trial
Hundreds of tonnes of household food waste has been used to produce biogas as part of a trial.
A total of 1,137 tonnes of unwanted food was collected from South Kesteven homes during a four-year trial.
Rather than being thrown away as landfill, the waste food was taken to an anaerobic digestion plant which produces biogas and soil conditioner.
In the past year alone, 203 tonnes of food was collected, with each home tossing out an average of around 93kg annually.
The trial began in 2018, although there was slight drop-off in food waste collected during the pandemic.
The trial was axed by South Kesteven District Council earlier this year due to lack of funding.
Each household was given one container for the kitchen and another for outdoors, with this being collected from the kerbside weekly.
Around 80 per cent of households participated initially, which declined as time went on.
The report into the scheme has been published as the government is considering making food waste collection compulsory for all councils.
It is estimated continued weekly food waste collections would cost £952,000 to £1,301,000 every year for the district, which could rise as petrol prices increase.
“The weight of food waste collected each month remained consistent over the first two years of the trial period, averaging 26 tonnes per month,” the report says.
“Although food waste collections continued during the Covid-19 pandemic restrictions, the amount of food waste collected reduced. Aligned to this, the amount of mixed dry recycling and residual waste increased significantly over the same period.
“This may be related to the restrictions placed on individuals resulting in them spending more time at home and revised arrangements at household recycling centres.”
While anaerobic digestion isn’t considered recycling, the council says it is preferable to the food ending up in bin bags in landfill.
The report will be discussed at South Kesteven’s environment scrutiny committee on Tuesday, May 10.
