Roads made from grass cuttings and ‘carbon-capturing’ cement are two of the projects awarded a share of £30m by the government for tackling the long-term decarbonisation of highways.
Seven projects across the UK have been awarded the funding and include an idea for asphalt to be made from green waste.
One involving the East Riding of Yorkshire Council will look at increasing the efficiency of low carbon lighting to make sure they can still be clearly seen by drivers.
The funding comes from the Live Labs 2: Decarbonising Local Roads competition, which supports projects led by local highways authorities.
Roads Minister Richard Holden said: “The UK is a world leader in technology and innovation and we must use that strength to drive decarbonisation and the next generation of high tech jobs that go alongside it.
“We are supporting this vital agenda to help level-up through £30 million funding for ground-breaking projects and boosting regional connections to support growth.”
