| Landfill Gas to be used to Run Garbage Trucks |

A new joint venture between North America's largest waste management company, Waste Management, and Linde, a leading gases and engineering company, is hoping to "close the loop" by producing fuel from garbage and using it to power garbage trucks. The companies will construct a liquefied natural gas (LNG) facility at the Altamont Landfill near Livermore in California that (when it begins operation next year) could produce up to 13,000 gallons a day of LNG. That gas will be used for vehicle fueling the collection trucks. Natural gas is already the cleanest burning fuel available for Waste Management trucks. Additionally, collecting methane for burning has an overall positive effect on global warming, because methane is a much more powerfull greenhouse gas than CO2. Linde North America estimates that capturing and reusing landfill gas could reduce greenhouse gas emissions by more than 30,000 tonnes per year.The LNG produced from the Altamont landfill gas will be a virtually zero-carbon transportation fuel and eventually lead to more facilities that can produce more than 200 million gallons of clean transportation each year from the garbage in California's landfills. There's a lot of garbage out there and any way it can be re-used instead of just letting it rot away in landfills is a great thing. Waste is a terrible thing to waste. Via TreeHugger

rather than burying the garbage & waiting for it to rot & turn into methane - a better idea would be to build an Anything into Oil plant & turn it directly into a fuel - that way you dont need a landfill at all - all metals could be recycled & everything else not metal could be directly converted to a fuel

A garbage to oil conversion would be considerably difficult and you'd have a problem with impurities from the waste. An anaerobic digester is as simple as putting a tent over the waste and attach a hose to the highest point. Run the gas through a wet scrubber and pump the biomethane into a tank or preexisting CNG pipelines.
In my county we get about 400 GWh/year from the dumps and are expanding the project thanks to the commercial success and increasing demand for biomethane. |

Science, technology gadgets and...baby seals. We're in a bit of an eco-mess, but we've got the brains to lick any problem. And that's why EcoGeek.org publishes up to ten stories daily about innovations that are saving the planet.
And if that sounds interesting to you, then congratulations, you're an EcoGeek.
Turning garbage into gold isn't going to happen anytime soon, but perhaps all that waste doesn't need to go...waste. Landfill gas, which comes from the natural decomposition of organic waste, can be purified and liquefied into clean fuel.
