If you heard about Michigan's response to the arrival of the emerald ash borer beetle (Agrilus agriplennis), which was to remove millions of infested ash trees, maybe you were wondering what they were doing with all that wood. According to this story from the Detroit Free Press, the state was converting the cut trees to wood chips to fuel a power plant. But now there's a company called LaMont Brothers Tree Service that has found a more efficient use. They take the trees, strip away the outer layers, and use the rest to make boards that can be used as railroad ties or to make furniture. They actually applied for and received a grant to do this work - you can read more about it here.
