300 garbage collection trucks in California will soon be fueled by the same trash that they haul. Landfill gas will be purified and liquefied, producing up to 13,000 gallons of liquefied natural gas (LNG) daily.

While the national average price of gasoline is now $3.60, some residents of Utah are happily filling up on compressed natural gas (CNG) at $0.63 per gallon. That’s the country’s lowest price for CNG, which has understandably caused a surge in demand for vehicles running on a fuel that one man described as “practically free.”

Maybe it was the martinis I had already drunk, or the beers he had already drunk, or maybe it’s just plain impossible to have a discussion about Biofuels without getting heated. But boy, did I have a doozy on Friday.

Somehow the discussion then veered away from Biofuels specifically and towards agriculture and GHG emissions in general. At which point, he presented his most sensational argument yet...

POET announced recently that it had reached an agreement with City of Sioux Falls to use methane (landfill gas) generated at the Sioux Falls Regional Sanitary Landfill to offset some of it's natural gas needs at it's Chancellor, SD ethanol plant.

Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. It is comprised primarily of methane and carbon dioxide. It can be combusted with oxygen and the energy release allows biogas to be used as a fuel. Considered a renewable fuel and electricity produced from it can be used to attract renewable energy subsidies in some parts of the world.

CO2 certainly gets most of the doomsday ink, and for good reason. In terms of sheer weight, it accounts for around 85 percent of America's greenhouse gas emissions, which amounted to 7.074 billion metric tons in 2004; methane accounts for just 8 percent of that frightening total.

It's a silent but deadly source of greenhouse gases that contributes more to global warming than the entire world transportation sector, yet politicians almost never discuss it, and environmental lobbyists and other green activist groups seem unaware of its existence.That may be because it's tough to take cow flatulence seriously. But livestock emissions are no joke. 

It’s Not Just Burping Cows, But the Land Cleared for Them to Graze

"Scientist Katey Walter tells Gelf how the melting Siberian permafrost is releasing tons of greenhouse gases into the air—and why that might be a good thing."

If you can't beat it use it!

The vegetarian society have launched an ad raising awareness of the contribution of animals to greenhouse gases.......

In conjunction with The Climate Trust, NW Natural from Oregon is now offering its clients carbon offsets by investing in methane capture systems.

Biodegradable corn plastics are the key to reducing landfill volume, right? Maybe not: get the real scoop on eco-plastic.
