Most used wind turbine blades end up in landfills

Wind turbines stand on the horizon beyond the Logan County Landfill on Feb. 12, 2020. The landfill is one of only a few that accept worn-out turbine blades from wind power operators updating their equipment. The blades are built to withstand high winds and sustained stress, and thus are a disposal challenge. (Andy Colwell, Special to The
