OLD chip fat can be recycled as a replacement for bitumen, so cutting the carbon footprint of the road building industry, a company claims.
Aggregate Industries said it had developed a way of using old vegetable oil instead of bitumen.
The development will help the environment, as 1.25m tonnes of bitumen, which is made up of crude oil, is used every year for road building, the firm said.
The Leicester-based company made the discovery during testing at its plant in Newark, Nottinghamshire.
It now wants to patent the invention before using the newly-developed asphalt across the country.
