Green Biologics Awarded Funding to Develop a New Low-cost 'Next Generation' Biofuel


An Oxfordshire biotechnology company is set to develop a new low-cost 'next generation' biofuel, with £250,000 funding from the Department of Trade and Industry-led Technology Programme and £310,000 from shareholder investors and business angels.

Green Biologics Ltd plans to develop a way of manufacturing biobutanol, identified as a superior 'next generation' biofuel for transport, which will slash the cost of production by up to a third. Biobutanol is currently used as a chemical feed for stock but high production costs have prevented it being widely used as a fuel.

Minister for Science and Innovation, Malcolm Wicks, said: "The development of biofuels is expected to play a major part in reducing transport emissions post 2020. We need companies like Green Biologics to work on developing the technology now needed to make new types of biofuel to help meet our future goals.

"Tackling climate change is a huge global challenge. We believe the UK must put its best efforts towards developing the new technologies we need to help cut carbon emissions. There's also a great economic opportunity for UK businesses in investing in this area."

Green Biologics Founder & CEO, Dr Edward Green, said: "Biofuels, such as biobutanol, are sustainable and environmentally friendly 'next generation' fuels that will extend, and ultimately replace, fossil fuels such as petrol and diesel. Although butanol is not currently used as a biofuel, it has a number of properties that make it extremely attractive. It is a renewable liquid fuel, produced from the fermentation of sugars, which can easily be integrated into the existing fuel infrastructure by blending with petrol. Unlike bioethanol, it offers similar energy per litre to petrol, has low vapour pressure and is easy to store, handle and transport via pipelines."

Biobutanol is produced by the clostridial fermentation of starch and sugars, a process first commercialised in 1916 to produce acetone for munitions for the war effort but which was displaced in the 1950s by a cheaper petrochemical method.

BP has recently announced a collaboration with Dupont and British Sugar to manufacture biobutanol using conventional technology in the UK. BP provides a route for butanol into the transport fuel market and aims to blend butanol with petrol at its 1200 filling stations. In addition, in an attempt to curb C02 emissions, the EU has suggested that biofuels should account for 5.75% of total fuel sales by 2010. More recently the Commission has proposed that biofuels should make up 10% of total fuel sales by 2020 which represents a huge increase in the market for biofuels.

Within the UK, the Renewable Transport Fuel Obligation will, from April 2008, require fuel suppliers to ensure that an increasing percentage of their total fuel sales are made up of biofuels by 2020. The Government intends that biobutanol should count as a renewable transport fuel under the RTFO. The Government is due to consult on the details of the RTFO very shortly.

Green Biologics is partnering with EKB Technology, a specialist in innovative process technology, to develop an advanced fermentation process for butanol with improved yields and productivity and to demonstrate lower production costs for its Butafuel(tm) product.

Dr Green explained: "The major barrier to butanol production has been the high cost of the conventional starch fermentation process. Our expertise in microbial strain development, together with EKB's innovative process technology and the use of non-edible food stocks, should lead to a step change in the economic viability of the manufacturing process - we are aiming for a two to three fold reduction in cost. We are effectively using our knowledge of enzymology, microbial physiology and fermentation to optimise and 're-commercialise' the butanol fermentation process."

Green Biologics is also expanding its staff numbers as it moves from a research to a development phase and Dr Green added: "New investment, together with significant grant funding, our collaboration with EKB Technologies, and the strengthening of our board with the appointment of Andrew Rickman OBE as Chairman are exciting developments. Dr Rickman founded Bookham Technology Inc, the world's second largest fibre optics telecom component producer and brings substantial management expertise and a hands-on approach that will be particularly valuable as we move to the next stage of demonstrating that we can produce our own Butafuel(tm) product."
