A Middlesbrough company is to become one of the first in the North East to run its vehicles using a cleaner, greener fuel.
Bio-diesel in growing in popularity
Bio-diesel, which is made from vegetable oil, will be used in a fleet of four vehicles operated by the Tees Forest company.
If it is deemed a success, the use of the fuel could be extended to Middlesbrough Council's vehicles in the near future.
Jonathan Scurlock, Renewables and Recyclables Manager for the Tees Forest, told BBC Radio Cleveland the switch to more environmental friendly fuel was a natural progression for the company.
He said: "North East Community Forests, as an organisation concerned with economically sustainable development, wanted to look at all aspects of our energy use.
"We have conducted some in-house recycling studies and we were also anxious that our own use of transport should be compatible with our own environmental aims."
