The Savoy says biomass electricity will light 10% of its rooms
London's Savoy Hotel plans to light up some of its rooms by recycling leftover food from its restaurants and turning it into electricity.
The hotel, which is closed as it undergoes a £100m refurbishment, said the power from biomass would be enough to light 10% of its 263 guest bedrooms.
Currently food waste and leftovers from its Simpson's-in-the Strand restaurant are recycled by the PDM Group.
The 1889-built hotel is due to reopen later this year.
At present leftovers are collected once a week for recycling which is expected to become a daily routine when the hotel reopens.
The food products are processed to recover liquid fat which is used in the manufacture of bio-fuels.
Bio-fuel is then processed in PDM Group's power plants to generate renewable electricity.
Debra Patterson, from the Savoy, said: "When the Savoy reopens it will be the most environmentally responsible hotel in London.
"We were delighted to find that PDM offered a solution that allowed us not only to reduce the amount of waste going to landfill, but to make a significant improvement to the Savoy's overall carbon footprint by displacing fossil fuels - a completely sustainable solution."
