They had a wood gassification plant producing electricity to run the Verso paper mill in Bucksport Maine. They shut the generating plant down a couple of years after the mill closed. I guess it wasn't commercially viable after energy prices dropped. It's a shame really .....
The way it used to work was that local wood cutters provided pulp wood to the mill. These were professional loggers with maybe a quarter million invested in heavy equipment. It used to be that they would either burn or win row the brush but when a market opened up for wood chips they started chipping it instead. They would save up the piles and when there was enough to fill an eighteen wheeler dump truck they would ship it off to the gassification plant to be made into electricity. Wood is a pretty low grade fuel so it never really was a big money thing. It was more that it was eco friendly.
You could use municipal wood waste like demolished houses and furniture but it wouldn't be a clean process. The left over wood ash would be contaminated with lead & arsenic. Each load would have tested and hauled off to a special landfill.
Most of the wood pellets that we're using are brought in by the train car load out of Canada. They're made from saw dust from the lumber mills. It's a little tricky to get the moisture content just right. If they're too wet you can get a load that won't burn. If they're too dry you can run into combustion problems in the burn chamber of the pellet stove.
Sometimes the simple answer is best. When it's the dead of winter and you're out of firewood just start busting up the furniture.
