Bloomberg says that the US Air Froce will be running on biofuels by 2013.  The Air Force is set to certify all of its 40-plus aircraft models to burn fuels derived from waste oils and plants by 2013, three years ahead of target.  Currently it pays $8 billion annually for traditional fossil fuels. The US military says it has been successful testing fuels produced from sources as diverse as animal fat, frying oils and camelina, an oil-bearing plant that’s relatively drought- and freeze-resistant. The Air Force has a 2016 deadline for being able to get half its needs from 50/50 alternative fuel blends, equivalent to 400 million gallons of biofuels or other combustibles, such as synthetic liquid fuels from coal and gas.

Belgium has a new biogas plant for electricity and heat according to Market Watch. The plant, to be 100% CO2 neutral, will mainly ferment corn that is grown in close cooperation with local farmers within a 15 km radius. The corn produces a biogas that will generate electricity.  The 3 MW of electricity will be fed into the local power grid. The heat resulting from the process is used to dry the fermentation substrates. These substrates are returned to the fields as low-odour, high-quality fertilisers for the corn crops.

Biomass will power a cheese factory in FinlandRenewable Energy Magazine reports that wood chips and peat will power a steam boiler which will generate the electricity and heat needed for a milk processing plant operated by the country’s largest milk producer.  The company produces cheese and whey products.  Eventually the boiler will use only wood chips but in the initial stage they will account for 50-60% of the fuel mix. The plant, to begin operations in 2013, will generate 140 MW of electricity.

A new anaerobic digestion plant has opened in Edgmond, Shropshire in the UK, which will convert 23,000 tonnes of food waste and cow slurry into biogas, feeding the electricity onto the local grid. The food waste comes from manufacturers, retailers and caterers and the slurry is provided by a 400 head herd of cattle. The 495 kW of electricity will be used by the Harper Adams University College which owns the dairy herd.

In Somerset, UK a biogas facility has been upgraded to double its outputBioenergy Insight tells us that the plant has been given approval to double its current capacity to power 4,000 homes. Currently the Cannington Enterprises plant uses an anaerobic digester to produce power from residue crops such as maize silage, grass, whole crop and big bale silage. Now it will be allowed to treat up to 75,000 tonnes of other waste such as rotting food.

The Times of India tells us that Delhi buses will be running on biofuel. The Delhi Transport Corporation has a deal with the Swedish government to set up a compressed biofuel plant at Delhi Jal Board’s Keshopur sewage treatment plant.  The plant will convert vegetable waste and sludge into biofuel which will be used to power Delhi buses. The fuel is said to be cheaper and cleaner than compressed natural gas. The plant will commence operations in 2013.

The city of North Bay, Ontario, Canada has commenced a landfill gas to electricity project.  The methane gas from the landfill will generate 1.6 MW of electricity that has the potential to power 1300 homes and offset approximately 45,000 tons of CO2 annually.

The county of Charlotte, Florida will also be turning its landfill methane gas into electricity.  Vertical gas vents will be used to collect methane from the decomposing trash. The methane gas will turn generators that will produce enough electricity for almost 4,000 homes.  The electricity will be sold to an Orlando company and the county will receive 20% of the annual revenue.

    Edmonton has announced a waste gasification project too, and CNET has a good story on the struggles in the US to draw a distinction between burning waste in a drum in your back yard (incineration) and the current practices of waste-to-energy projects. The waste, in the latter case, is whatever can’t be recycled, so this isn’t a substitute for recycling programs etc. See the story here:
