Lebanon has started operating its downdraft gasification plant on Hartmann Drive that officials say will eventually divert more than 8,000 tons of waste going to landfills a year.
The approximate $3.5 million facility opened this week, according to Lebanon project manager Scott McRae, and will convert waste wood, tires and sewer sludge to electricity to help power the city’s wastewater treatment plant. A percentage of the converted waste also becomes a high carbon biochar to be recycled or sold for agricultural or industrial uses.
The Lebanon City Council approved a contract in 2015 with PHG Energy to build the plant, which now is operating on a limited basis with plans to “ramp up” in the coming months, McRae said.

On Oct. 3, the USDA released a new report showing that the biobased products industry contributed $393 billion and 4.2 million jobs to America’s economy in 2014. From 2013 to 2014, the sector created new 220,000 jobs and grew by $24 billion.
The new report, commissioned by the USDA BioPreferred Program, is the second Economic Impact Analysis of the U.S. Biobased Products Industry released by the USDA. It analyzes revenue and jobs created by the biobased products industry at the national and state level in 2014. The first report, released last year, analyzed 2013 data.

Paul Gilman wants your trash.
Gilman isn’t a hoarder, and he maintains an admirable standard of personal cleanliness. But when he passes the dumpsters linked up at the end of driveways on trash day, filled with unwanted garbage to be taken to a landfill, all he sees is waste. To Gilman, chief sustainability officer at Covanta Energy, garbage represents an untapped and surprisingly clean source of energy.
The world is drowning in garbage. Between squalid dumps outside of slums, landfills tucked away into economically disadvantaged neighborhoods, and the tons of plastic endlessly circulating in the ocean, our trash is polluting every last nook and cranny of the planet. At the same time, humanity is using up the world’s fossil fuels at an ever faster clip, throwing tons of carbon dioxide into the atmosphere and depleting reserves of oil and coal. Gilman and advocates of waste-to-energy approaches believe that they can solve both problems simultaneously.

Work is progressing at the city of Lebanon, Tennessee, waste-to-energy plant, and Field Rep. Evann Freeman from Sen. Lamar Alexander’s office recently visited the site to check in on progress.
The waste gasification plant was designed and is being built by PHG Energy, which constructed a similar plant in Covington, Tennessee. At the time of Freeman’s visit, construction on the support tower was underway, and completion of the project remains on track to allow for an October commissioning.
The biomass gasification plant will deploy what PHG Energy believes will be the world’s largest downdraft gasifier, eventually converting as much as 64 tons per day of wood waste, sewer sludge and used tires into up to 400 kilowatts of electricity for use at Lebanon’s waste-water treatment plant.
