Primary schools, community organisations and growing groups in Spalding, Boston and Skegness have pledged to get composting for a new contest.
Five schools from South Holland are among a dozen schools and groups across the three areas registered to join the Anglian Water Keep It Clear Fat of the Land Composting Challenge, in association with Lincolnshire Community and Voluntary Service.
Free specialist composting bins, worth around £180 each, have been presented to each of them and a total of 600 giant pumpkin seeds.
Collette Parker, Keep It Clear customer engagement manager, said: “We are thrilled so many people have embraced the contest which is all about raising awareness of compost bins now available that allow food waste to be recycled.
“Getting people recycling food waste helps to ensure fats, oils and other items are kept well away from drains.
“Putting those items in drains causes costly, unpleasant and inconvenient blockages whilst composting allows them to be put to great use, helping gardens to thrive.”
The groups and schools that have signed up to the Fat of the Land Composting Challenge are now going head-to-head to try to win gardening vouchers totalling £1,200.
To win they will need to keep their composting bins topped up and demonstrate the results.
All have been challenged to create an innovative gardening project incorporating composting and grow the biggest pumpkin.
The Anglian Water Keep It Clear campaign is raising awareness of the need for fats, oils, food waste, wipes and sanitary waste to be kept out of drains and toilets.
South Holland schools involved are: Spalding St John the Baptist Primary, Spalding Parish Church of England, West Pinchbeck St Bartholomews Primary, Spalding Monkshouse Primary and Spalding Friends of Sir Gleed School.
Entries will be judged during the first week of October.
