A new report says that biofuels contributed $277 billion to the global economy in 2010 we learn from Biofuels Digest. The Global Renewable Fuels Alliance and Cardno Entri found that global biofuel production produced 110 billion litres in 2010. The amount of ethanol produced globally has doubled since 2005 and increased three-fold in the last decade. By 2020 the global biofuel industry is expected to grow to produce about 200 billion litres.  You can see the report here.

The Energy Tribune looks at the cost of producing biofuel from algae and pyrolysis. (Pyrolysis chemically decomposes organic materials by heat in the absence of oxygen. It typically occurs under pressure and at operating temperatures above 430 C (800 F). The author looks at recent projections from the US Department of Energy on the cost of making biofuel from algae compared with pyrolysis and concludes that the latter approach is more likely to become cost competitive with gasoline and diesel as a transportation fuel.

There were two articles this week about the debate over the costs and benefits of biofuels and particularly their impact on the environment. Green Chip Stocks says the Biofuel Debate Continues and lists the pros and cons of biofuels. Cons include taking away land for food, removing habit for plants and animals, and producing harmful nitrous oxide. businessGreen focuses on the on-going debate within the European Union as environmentalists assert that the use of bioenergy has the potential to raise CO2 emissions and push up food prices, negating the emissions savings that should result from switching from fossil fuels to biofuels.

Cogeneration & On-Site Power Production reports that Turkey has its first biogas power plant. Located in Cicekdag, it will process 50 tonnes of cow and sheep manure daily to produce 3000 cubic meters of biogas. A co-generation unit will convert the biogas into electricity (249 kW) and heat (200 kW).

Biogas digesters will power an ethanol plant in the US state of Kansas. The BC Democrat says four anaerobic digesters are replacing natural gas with methane gas derived from feedyard manure, hog carcasses and other farm and municipal wastes. The methane will be used to provide energy to enable Western Plains Energy to manufacture corn ethanol for automobiles. The company produces 50 million gallons annually.

The Stratford Beacon Herald tells us about a dairy farm in the Canadian province of Ontario that will burn methane from cow manure and added organic waste to generate electricity. When fully operational, the farm will produce enough electricity to power 500 homes.

College students in the US state of Arizona are using dog waste to light up a city park in Gilbert according to Environmental Protection. The Leader says that the idea of using dog waste to generate electricity is also being explored in Flintshire county in England. This story is covered by TriplePundit Streetkleen Taps Man’s Best Friend for Renewable Biogas.

Paragon Agro, an agro company in Bangladesh, is using poultry waste to generate electricity says The Daily Star. The company has built three plants to generate a total combined total of 475 KW of electricity operate its poultry plants. Captured heat is used to produce hot water in the hot water tanks to maintain an effective temperature in the digesters. Poultry waste is an input for the biogas digesters to produce biogas, which after purification is supplied to run gas generators to produce electricity.

Bdaily Business Network writes about the benefits of anaerobic digestion for converting waste to energy.

Haiti is going to convert household waste into electricity reports defend. The government has signed an agreement to construct a 30 MWwaste to energy plant to power Port – au-Prince.

Several steel and textile mills in the Indian state of Tamil Nadu are using agro waste briquettes instead of coal or sawdust to produce heat. Agro briquettes are prepared by using residue like paddy straw, cotton and soya bean stalk. The straw is shredded and the powder sent to a feeder where high pressure converts it into briquette. The lignin (organic polymer) in the straw acts as a binder and so briquette production doesn’t need water.
