McDonalds plans to roll out its waste to energy pilot and has called the scheme a success.
Waste from 11 restaurants which took part in the scheme in Sheffield was collected and used to produce electricity for use in local buildings.
The Carbon Trust, who worked with McDonalds to audit the project, said it had cut is carbon impact from waste disposal by 54%.
Waste from the restaurants was collected by waste contractor, Veolia Environmental Services, who treated it at a nearby energy-from-waste facility where the power was produced to help heat and light Sheffield City Hall and Weston Park Hospital.
A McDonalds spokeswoman said: We are working hard with our waste contractor to identify opportunities to roll this successful programme out more widely. However, we continue to face some significant infrastructure and planning challenges which mean that we will be unable to extend the scheme nationwide overnight.
In the meantime, however, we are continuing to reduce our environmental impact in a range of other ways, from exploring other sources of renewable energy to reducing and improving the materials we use in our packaging.
