Wind Turbine Blade Recycling Has Tons of Potential

SEATTLE (Waste Advantage): The Electric Power Research Institute (EPRI), in collaboration with the American Composite Manufacturers Association (ACMA), addresses scientific questions related to recycling millions of tons of wind turbine blades that would otherwise end up in landfills, in a recently published report. The analysis provides guidance on wind power industry R&D priorities, including the magnitude of the wind turbine blade waste issue, potential recycling and repurposing solutions, and next steps for research and development.

“By 2050, the industry could send approximately 4 million tons of wind turbine blades to U.S. landfills,” said EPRI Senior Technical Executive Ken Ladwig. “This report points to promising technologies to avoid waste disposal and explores the need for further review and development of recycling technologies. It also shows us the need for the collaborative development of a commercial-scale facility to process blades at the end of their useful life, as a key aspect of a sustainable and economically viable solution.”

The commercially available technologies reviewed by the report include:

-Turbine blade life extension.

– Pyrolysis (a process to repurpose materials from composites for energy).

– Cement kilns applications.

– Grinding turbine blades to re-use them as filler material in a variety of products.
