WindEurope CEO visits German cement plant that’s running on blade waste | WindEurope

On 4 October WindEurope CEO Giles Dickson visited Holcim’s Lägerdorf plant in Germany, together with Claudia Grotz of Siemens Gamesa and Chair of WindEurope’s Sustainability Working Group. They met the Geocycle team who are using wind turbines blade waste to generate heat and ash to help make cement. It’s currently the only such cement plant in Europe that’s using blade waste.

The organic content of blade waste is recovered as thermal energy while the mineral fraction of the waste is integrated as ash in the matrix of the cement clinker the plant produces.  This reduces the carbon footprint of cement production and makes it more resource efficient.  This is because the blade waste substitutes (partially) for fossil fuels in the incineration process and for other materials in the clinker production process.  One tonne of blade waste reduces CO2 emissions by 110 kg and saves 461 kg of raw materials.

Casper Regional Landfill begins burying turbine blades

A semi-truck hauls a turbine blade to the Casper Regional Landfill to be disposed of.

They are making a pretty large profit from the deal; $675,485 to be exact. “So the revenue from the special projects, um, that go in the unlined area, help with the whole cost of our facility so it keeps all of our rates low. Helping with the revenue source, so absolutely, we’re making money on it.”
