Madison company aims to turn pulpwood into insulation, reducing buildings' energy use
GO Lab is retrofitting a former paper mill in Madison to process low-quality byproducts of the state's lumber industry — softwood sawmill chips and timber-harvest detritus that right now are hard to sell. They'll turn it into wood-fiber insulation, called Timber HP. Some 230 million tons worth a year.
