Des Moines, IA – A local company is finding an innovative second life for discarded wind turbine blades, transforming the massive composite structures into durable concrete barriers. This initiative addresses a growing environmental challenge – what to do with aging wind turbine blades – while simultaneously providing a sustainable solution for infrastructure needs across Iowa and beyond.
The problem of wind turbine blade disposal has become increasingly pressing as older turbines are decommissioned. Traditionally, these blades, often made of fiberglass and resin, have ended up in landfills. However, a Des Moines-based company is pioneering a method to repurpose these materials, turning them into robust and cost-effective concrete barriers used for parking lot protection, traffic control, and security applications. This process not only diverts waste from landfills but similarly reduces the demand for virgin materials in concrete production.
From Turbine to Traffic Control
The company’s process involves breaking down the wind turbine blades and incorporating the resulting material into a specialized concrete mix. This recycled content enhances the concrete’s strength and durability, making it suitable for a variety of applications. One notable example of this repurposing is the refurbished parking lot at Premier Credit Union in Downtown Des Moines. The barriers installed there demonstrate the practical application and aesthetic appeal of the recycled material. Premier Credit Union, headquartered in Des Moines, Iowa, has assets totaling $125,102,692 and serves 15,029 members from four locations, according to publicly available data.
The use of these barriers at the Premier Credit Union’s main branch, located at 800 9th St in Des Moines, showcases a commitment to sustainable practices within the local business community. The credit union, which can be reached at (515) 282-1611, has been a fixture in the Des Moines area since 1933. The company’s innovative approach offers a viable alternative to traditional concrete barriers, reducing environmental impact and promoting a circular economy.
Addressing a Growing Waste Stream
Wind turbine blades are designed to withstand extreme weather conditions for decades, making them incredibly durable. However, this durability also presents a challenge when it comes to disposal. The blades are difficult to break down using conventional methods, and their size makes them unsuitable for many recycling processes. The company’s technology overcomes these hurdles by efficiently processing the blades and integrating them into a valuable construction material.
The company was chartered on January 1, 1933, and operates under charter number 64271. CEO Steve Flamm leads the organization, which is insured by the NCUA. The initiative aligns with broader efforts to promote sustainability within the renewable energy sector, addressing the lifecycle impact of wind power infrastructure. The company is a member of the Federal Home Loan Bank (FHLB) and is classified as a Federally Insured State-Chartered Credit Union.
Benefits and Applications
Beyond diverting waste from landfills, the use of recycled wind turbine blade material in concrete offers several benefits. The resulting concrete exhibits enhanced strength and durability, potentially extending the lifespan of infrastructure projects. The process reduces the carbon footprint associated with concrete production, as it requires less energy and fewer virgin materials.
The applications for these recycled concrete barriers are diverse, ranging from parking lot protection and traffic control to security perimeters and erosion control. The company is actively exploring fresh applications and partnerships to expand the reach of its sustainable solution. They offer a range of services including automatic teller machines (ATMs), home banking via internet, and mobile banking. They also provide business loans, real estate loans, and share accounts.
The company currently operates four branch locations: Ames (520 Grand Ave), Des Moines (Main Branch at 800 9th St and Skywalk at 700 Locust St), and West Des Moines (1301 Grand Ave). These locations provide access to the company’s financial services and demonstrate its commitment to serving the community.
As the renewable energy sector continues to grow, the issue of wind turbine blade disposal will only become more significant. This innovative approach offers a promising solution, transforming a waste stream into a valuable resource and contributing to a more sustainable future. The company’s work highlights the potential for circular economy principles to address environmental challenges and drive economic innovation.
Looking ahead, the company plans to scale up its operations and expand its partnerships with municipalities and businesses seeking sustainable infrastructure solutions. Further research and development will focus on optimizing the concrete mix and exploring new applications for the recycled material. The success of this initiative could pave the way for similar programs across the country, reducing landfill waste and promoting a more circular economy within the renewable energy sector.
