Dirt and grit swept up from roads is to be recycled for the first time, a council says.
Broadland District Council claims to be the first in the country to divert grit away from landfill sites and reuse it for local landscaping.
Up to 2,500 tonnes of road and pavement sweepings are to be recycled each year as part of the pilot project.
A council spokesman said the project will help preserve landfill space and increase the amount of waste recycled.
Broadland's portfolio holder for housing and environmental services, Roger Foulger, said: "One of the landfill sites we use will be closing in April because it is full.
"We recognise our responsibility both to manage our waste in a more sustainable way, and to preserve landfill space in Norfolk."
