Powering Buses from Waste
Stagecoach has launched a fleet of greener buses powered by household rubbish and animal waste.
The recycled waste is converted into biomethane, which will reduce carbon emissions from the buses by up to 40% and help cut landfill.
The innovative project has been launched in Lincoln, in partnership with Lincolnshire County Council and the East Midlands Development Agency, and involves 11 Optare Solo buses which have been converted to run on the low carbon fuel.
The direct £260,000 conversion costs have been funded by Lincolnshire County Council and the East Midlands Development Agency with Stagecoach East Midlands providing the buses from its Lincoln fleet. A further £100,000 joint funding has been invested in fuelling infrastructure.
The biomethane gas used to power the buses is derived from natural household and animal waste. The vehicle initially runs on diesel but a special gas electronic control system gradually reduces the use of the fossil fuel replacing it with biomethane without affecting the characteristics or performance of the bus. The converted vehicles are expected to deliver at least a 40% carbon savings compared to standard buses as well as improving fuel consumption. All 11 vehicles have also been fully refurbished.
In England, 11.9 million tonnes of waste is sent to landfill each year. The project will benefit the environment by converting household waste, which would otherwise go to landfill, into biomethane fuel.
