Special chewing gum bins are being tested in Lincoln to try to stop people throwing gum on to pavements.
They are being installed in three places in the city, and council chiefs say they will be increased if they prove a success.
It currently has to use high-pressure water jets to remove gum that has become stuck to walkways and roads.
Council leader Ric Metcalfe said: "Gum is a real nuisance and a blot on the landscape of many of our streets."
The three green bins will be situated in Cornhill, the High Street and Silver Street.
Kate Bell, community environment co-ordinator at the council, said: "If you are surrounded by litter, you think your contribution will make no difference.
"So if we can encourage people to think about disposing their gum responsibly, hopefully it will lead to cleaner streets in Lincoln."
