Poo Power rises

Don't underestimate the chemical power of waste and sh*t (I think I've just been bleeped!)

In Manchester, UK, United Utilities and National Grid have teamed up in building a plant producing biomethane from wastewater sludge. The plant will soon power up a small town of about 5,000 homes as well as fleet of sludge trucks.

The GBP4.3 million ($7.1m) project will be operational by early 2011, and involves installing the upgrade equipment, a gas compression and fuelling station, plus a pipeline to link into the local gas distribution network.

United Utilities said one of its sludge tankers has already been converted to run on diesel and compressed biomethane gas.

In California, USA, EnerTech Environmental commissioned its first ever biosolids-to-renewable energy SlurryCarbâ„¢ facility, that will generate 60,000 tons of fuel called E-fuel from over 270,000 wet tons of biosolids per year.

The E-Fuel produced by the facility is already being used by Southern California cement kilns to offset their coal use and will reduce annual local greenhouse gas emissions by over 80,000 tons.
EnerTech said biosolids (processed sewage sludge) in the US are produced at over 7 million tons each year.

In Brazil, engineering company ARCADIS opened its third landfill gas (LFG) plant near Rio de Janeiro named Novo Gramacho. The new plant will consolidate the leading market position of Biogas, a company in which ARCADIS Logos holds 33%.

Novo Gramacho has been developed to collect and burn the methane gas emitted in the Gramacho landfill where 2.4 million tons of urban waste has been buried every year for the last 30 years.

Finally, a post from New York Times Green Inc. blog talked about the power of chicken droppings, which can be converted into biochar fertilizer (highly porous charcoal made from organic waste), biogas, and bio-oil, using the process called pyrolysis.

"With 30,000 chicken farms in the United States alone, the market for this technology could be ripe for the picking -- particularly given that American consumers, over the last several decades, have been eating more and more chicken."
