The Oregon Department of Forestry is teaming up with the owner of 33,000 acres of private timberland west of Bend to test a new technology that reduces the amount of smoke produced during pile burning activities, and reduces wildfire risk. A pilot project is set to be held in October on Shanda Asset Management’s Skyline Forest, a vast swath of timberland that has long been the target of conservation efforts. The project entails using an air curtain burner — a container-sized unit that burns wood slash from thinning projects. Instead of releasing particulate matter into the atmosphere, these units capture smoke and produce biochar. It also reduces the risk of a wildfire caused by embers escaping from burning piles. Another advantage is limiting the spread of tree disease and insects — air curtain burners have proven to be better than pile burning when containment is needed.
