Waste Management World told us that landfills could power 5.2 million US households. A recently published study conducted by the Earth Engineering Center (EEC) of Columbia University says that the energy potential in non-recycled plastic is at least enough to fuel 6 million cars or power 5.2 million homes each year. Over 85% if plastic in the US ends up in landfills. New technologies can now turn non-recycled plastics into crude oil, electricity and other fuels.  You can read the study hereEnergy Digital also covered this story.  As did Earth Techling here.

From Waste Management World we also learned that a waste-to-energy facility has been approved for Stewartby in the UK.  The facility will treat approximately 585,000 tonnes of residual waste per year and convert it into 65 MW of electricity, of which 55 MW will be exported to the national grid.

OILPRICE said that Finland will open the world’s largest gasification plant. The 140MW facility in the city of Vassa will mainly on forest waste. The plant will use forest residues for fuel, with the resulting gas then combusted alongside coal. It is due to begin operating by end-2012. It should replace between 25 and 40% of the coal currently burned – reducing carbon dioxide emissions by some 230,000 tonnes per year.

A plant to produce biodiesel, ethanol, electricity and natural gas from a new integrated biorefinery is to be built in South Africa next year according to BioEnergy News. The biorefinery will produce 10 MW of electricity each day and 10 million gallons of ethanol and 10 million gallons of biodiesel every year. It will use either crops or organic waste to produce the fuel and electricity.

BioEnergy News reported that an anaerobic digestion plant has been given approval to be built in Mitcham, UK. The plant will use organic food waste from surrounding pubs and restaurants, converting it into electricity for the facility and for the grid. The facility will generate between 2,558 – 7,291 MW of heat for export to adjacent buildings and would heat between 250 and 730 houses. It would also generate potentially between 8,758 – 13,491 MW of electricity per annum and this would be sufficient to power the facility (5,464 MW) and deliver between 3,294 – 8,074 MW to the national grid.

Anchorage, Alaska is turning its landfill trash into electricity. The methane gas from decomposing garbage will be converted into electricity to provide 23% of the requirements of a nearby military base.

We learned from The West Ranch Beacon that a  9.2 MW facility at the Santa Clarita Valley’s Chiquita Canyon landfill in California will convert methane gas from the landfill into energy. The electricity will be sold to cities of Burbank and Pasadena through a 20-year power purchase agreement.
