London Busses Are Now Being Powered By Coffee Biofuel

Lots of the city's 9,500 buses already run on biofuel derived from food waste, specifically cooking oil and beef tallow, and London's mayor Sadiq Khan has set an even more ambitious goal of creating a zero-emission transit system for the entire city by 2050.

-Biofuel made using waste products such as tallow from meat processing and cooking oil had already supplied in numerous capital's 9,500 buses. The company collects waste from high street coffee shops, as well as instant coffee factories, and uses it to extract an oil. According to official figures in 2015, London's buses used 240 million liters of diesel fuel a year. Buses can be powered using the fuel without the need for modification, it said. Founder Arthur Kay said it was a "great example of what can be done when we start to reimagine waste as an untapped resource".

The fuel provides a cleaner, sustainable energy solution which will lower bus emissions in the United Kingdom capitol. Coffee-based oil does have a strong smell of coffee, Bio-bean said, "but once it is processed, distilled, blended and mixed with mineral diesel, that odor is removed".

The coffee fuel technology has been supported by Shell.

With the average Londoner drinking 2.3 cups of coffee a day, more than 200,000 tonnes of waste is produced that would otherwise end up in landfill.

The collaboration with Shell is part of the oil giant's #makethefuture energy initiative, which supports entrepreneurs working on low carbon innovations.

Sinead Lynch, Shell UK country chair, said the company is always looking for the next inventive solution. "We're pleased to be able to support bio-bean to trial this innovative new energy solution which can help to power buses, keeping Londoners moving around the city - powered in part by their waste coffee grounds".
