Timber is processed in high-tech, low-waste mills where lasers scan logs in three dimensions, computers decide the maximum number of boards, and every inch of log, down to the chips and sawdust, is put to use. Many mills generate their own electrical energy from these wood by-products. Photo: Courtesy of Oregon Forest Resources Institute.
