London Buses Get Greener by Running on Meat Waste

24 December 2015

UK - Almost a third of London's bus fleet will soon be running on a greener blend of diesel, made from blending diesel with renewable biodiesel from waste products, including cooking oil and tallow from the meat processing trade.

The new fuel will result in a huge reduction in CO2 emissions of 21,000 tonnes each year which comes on top of the 48,000 tonne CO2 reduction from 2013 levels as a result of the introduction of lower emitting buses such as hybrids.

Two bus operators, Stagecoach and Metroline, have signed deals with Argent Energy to supply them with B20 green diesel. 

By March next year, almost 3,000 of the capital's 8,900 buses will be powered by the B20 fuel blend. Six hundred and forty-two buses operating out of four Stagecoach depots have already been using B20 for two months on a trial basis.

Deputy Mayor for Environment and Energy, Matthew Pencharz, said: "As a leading global city London has an important role to play in reducing greenhouse gases and minimising our contribution to climate change.

"Just a fortnight after the Mayor's visit to the Paris conference on preventing global warming, I am very pleased to announce that nearly a third of London's buses will now be running on biodiesel, slashing the overall carbon emissions of the fleet and making use of fuels that would otherwise be clogging up our drains. These buses will be a proud addition to what is already the greenest bus fleet in the world, including hybrid, pure electric and pure hydrogen vehicles.

"This is ongoing progress for running our bus fleets on waste products and cutting CO2. We will continue to work with our industry partners to use more of London's used cooking oil turned into biodiesel right here in the city, creating green jobs and fuel self-sufficiency benefits."

Mike Weston, TfL's Director of Buses, said: "Our bus fleet is now making a major contribution to improving air quality and bringing down CO2 emissions.

"This improvement, which will reduce CO2 emissions by 21,000 tonnes each year, is being introduced now with no extra spend needed and no long delay for the fitting of new kit. It's just one of a number of measures we are taking to make London's environment better for everyone."

Biodiesel is a renewable, clean-burning fuel. TfL requires that biodiesel blended into B20 for London buses is made from waste, rather than crop-based feedstocks. It is estimated that buses running on waste-based B20 produce 10 per cent less 'well to wheel' carbon emissions than a bus using ordinary diesel.

London's bus network is one of the largest in the world, carrying almost 2.4 billion passengers a year. Currently, the 8,900-strong bus fleet uses around 240 million litres of fuel each year. Under the new deals, about 80 million litres of the new greener blend of fuel per year will be consumed.

The technology will be trialled on route 69 in east London, which runs between Canning Town and Walthamstow bus stations.
