The US Department of Energy (DOE) has released an encouraging new report revealing that 90% of wind turbine materials are already recyclable using existing infrastructure, but tackling the remaining 10% needs innovation.
That’s why the Biden administration’s Bipartisan Infrastructure Law has allocated over $20 million to develop technologies that address these challenges.
Why this matters
The wind energy industry is growing rapidly, but questions about what happens to turbines at the end of their life are critical. Recyclable wind turbines means not only less waste but also a more affordable and sustainable energy future.
According to Jeff Marootian, principal deputy assistant secretary for the Office of Energy Efficiency and Renewable Energy, “The US already has the ability to recycle most wind turbine materials, so achieving a fully sustainable domestic wind energy industry is well within reach.”
The report, titled, “Recycling Wind Energy Systems in the United States Part 1: Providing a Baseline for America’s Wind Energy Recycling Infrastructure for Wind Turbines and Systems,” identifies short-, medium-, and long-term research, development, and demonstration priorities along the life cycle of wind turbines. Developed by researchers at the National Renewable Energy Laboratory, with help from Oak Ridge and Sandia National Laboratories, the findings aim to guide future investments and technological innovations.
What’s easily recyclable and what’s not
The bulk of a wind turbine – towers, foundations, and steel-based drivetrain components – is relatively easy to recycle. However, components like blades, generators, and nacelle covers are tougher to process.
Blades, for instance, are often made from hard-to-recycle materials like thermoset resins, but switching to recyclable thermoplastics could be a game changer. Innovations like chemical dissolution and pyrolysis could make blade recycling more viable in the near future.
Critical materials like nickel, cobalt, and zinc used in generators and power electronics are particularly important to recover.
Key strategies for a circular economy
To make the wind energy sector fully sustainable, the DOE report emphasizes the adoption of measures such as:
Better decommissioning practices – Improving how turbine materials are collected and sorted at the end of their life cycle.
Strategic recycling sites – Locating recycling facilities closer to where turbines are decommissioned to reduce costs and emissions.
Advanced material substitution – Using recyclable and affordable materials in manufacturing.
Optimized material recovery –Developing methods to make recovered materials usable in second-life applications.
Looking ahead
The DOE’s research also underscores the importance of regional factors, such as the availability of skilled workers and transportation logistics, in building a cost-effective recycling infrastructure. As the US continues to expand its wind energy capacity, these findings provide a roadmap for minimizing waste and maximizing sustainability.

Global airport ground support equipment (GSE) manufacturer Mallaghan just deployed what it says is North America’s first ever fully electric refrigerated catering truck designed specifically for the aviation industry.
Co-developed by Mallagha and International Motors (formerly Navistar), the Mallaghan CT6000E was unveiled at a ceremony at Logan International Airport in Boston that was attended by Massachusetts Governor Maura Healey, State Representative Adrian Madaro, and Boston City Councilor Gabriela Coletta-Zopata.
“This launch marks a significant milestone for both Mallaghan and the aviation industry as a whole in North America,” said Joe Griffith, Chief Commercial Officer at Mallaghan. “The CT6000E not only reinforces our commitment to innovation and sustainability but also supports our partners in their pursuit of greener, safer, and more efficient (aviation) operations.”
As a truck, the CT6000E shown in Boston looks to be based on the same International eMV chassis that underpins New England’s HazMat1 fire truck. The eMV features a 33,000 lb. GVWR, a direct-drive electric motor packing 1,737 lb-ft of peak torque, and 135 miles of range from its 210 kWh li-ion battery pack. The eMV also features a robust aux system powered by a pair of AGM 12V batteries that charge through the main 609V high voltage system.
To help it serve its aviation mission as GSE, the CT6000E which features a number of new technologies aimed at both vehicle efficiency and operator safety, including an advanced aircraft-controlled approach system (CAS) to help reduce aircraft damage, 360-degree Birds Eye camera system with onboard hard drive, and on-board telemetry.
Mallaghan’s CT6000E will be operated by premium airline catering company, DO & CO, whose international roster of clients includes American Airlines, Delta, gategourmet, IAG, Southwest Airlines, Qatar Airways, and Servair.
Electrek’s Take
While this International-based CT6000E is the first such refrigerated electric catering truck in the US, it’s mest certainly not the first suck truck Mallaghan has put into service. Those two photos, above, show a very similar product from Mallaghan (confusingly called CT6000e) based on the Volvo FL Electric. That truck was first launched back in 2019.
With the short distances driven at limited speeds under extreme loads, GSE at airports present a nearly ideal use case for battery-electric vehicles. That’s a good thing, too — as demand for on-road fossil fuels drops, airports and airlines – historically responsible for about 4% Earth’s global warming – are becoming a bigger and bigger slice of a rapidly shrinking pie when it comes to fossil fuel emissions.
They may not purr like a well-tuned diesel, but Pet Valu has added two brand-new, whisper-quiet Volvo VNR Electric semi trucks to its growing logistics fleet as part of the company’s ongoing effort to transform its supply chain into one that’s more efficient, and more sustainable.
Pet Valu is one of Canada’s leading specialty retailers, offering a wide variety of pet food, toys, and and other fur-and-feather friendly supplies to keep pets healthy and happy. Part of the company’s efforts to deliver on that happy/healthy promise is in reducing ground-level air pollution, and these new, zero-tailpipe emission electric semi trucks will help Pet Valu achieve that vision.
“At Pet Valu, we are committed to continuously improving how we serve devoted pet lovers and their pets,” explains Nico Weidel, chief supply chain officer, Pet Valu. “Each electric delivery truck represents an opportunity to avoid consuming over 25,000 liters of diesel fuel or over 62 tonnes of CO2 (emissions) per year. We’re excited to explore how these trucks perform and assess the potential for further electrification of our delivery fleet in the future.”
Pet Valu spec’ed out its new Class 8 Volvo VNR Electric day cab trucks with the 565 kWh six-battery pack configuration, offering route drivers an operating range of up to 442 kilometers (about 275 miles) per charge. And, while Volvo’s VNRs are capable of ultra-fast charging, these trucks will power up overnight overnight at the company’s Surrey distribution center an a newly installed 120 kW charger.
In addition to deploying the trucks, the Volvo Trucks team worked closely with Pet Valu to identify and secure additional funding opportunities to help offset the high up-front cost of the battery-electric semis, including federal (Canadian) and provincial incentive programs Clean BC – Go Electric and iMHZEV (incentives for Medium- and Heavy-Duty Zero-Emission Vehicles).
“We are excited to see Pet Valu taking the initiative in the Canadian pet supply industry by adopting Volvo’s VNR Electric trucks,” says Matthew Blackman, managing director for Canada, Volvo Trucks North America. “As they venture into sustainable transportation, this effort is expected to not only strengthen their supply chain but also help support a healthier planet, one ‘purr-fectly’ quiet kilometer at a time.”
And, yes: we made the same joke. (I stand by it.)
