Missouri plant turns old wind turbine blades into cement feedstock

Outside Casper, pieces of turbine blades cut through were lowered by a loader into a trench for years. Now, what they are being used for instead of being buried under the ground, is to make cement powder. And this transition is worth noting.The Casper Regional Landfill took its first decommissioned blades in the spring of 2019. By the following September the running total stood at 1,124 blades, arriving from three wind farms in the surrounding country.Each one came in at roughly 120 feet and was cut into three 40-foot lengths before it could be moved or stacked. The smaller sections were then nested inside the larger ones, which is the only way to stop a single blade swallowing an unreasonable share of the trench.
