Looming Waste Crisis: Thousands of Solar Panels and Wind Turbines Face Recycling Challenges
As the world embraces renewable energy sources like solar and wind power, a significant problem is emerging: what happens to the waste created by damaged or decommissioned infrastructure? In Brooks, Alberta, Dan Carrocci, president of Sunset Renewable Asset Management, stands in a growing problem. Inside a former pheasant hatchery, he has amassed nearly 10,000 damaged solar panels, hoping to develop a commercially viable recycling solution for this “big green elephant” of renewable energy waste.
With the installation of solar and wind energy systems increasing at a rapid pace, the amount of waste generated by these technologies is expected to skyrocket. According to a report from the University of Ottawa’s Smart Prosperity Institute, Canada could see up to 470,000 tonnes of solar panel waste and 4.5 million tonnes of wind turbine waste by 2050. Most of this infrastructure is still relatively new, but the country faces a mounting challenge to handle this waste sustainably.
The Waste Problem in Renewable Energy
Carrocci has worked in renewable energy for over a decade and is deeply concerned about the lack of end-of-life options for solar panels and wind turbines. Many of the panels he has collected were damaged during manufacturing, installation, or by natural disasters like hail. Currently, there is no efficient way to recycle the various materials that make up solar panels, which are 85-90% recyclable, but difficult and costly to process.
This is not an isolated issue. While Canada is ramping up its renewable energy infrastructure, the lack of recycling programs for end-of-life solar panels and wind turbines is becoming a serious concern. Without proper systems in place, most of these materials will end up in landfills, creating further environmental challenges.
Potential Solutions and Business Opportunities
Despite the challenges, some companies and experts are seeing the profit potential. Evan Wilson, vice president of the Canadian Renewable Energy Association (CanREA), believes businesses that develop recycling solutions for solar panels and wind turbines today will thrive in the future. Both solar panels and wind turbine blades contain valuable materials that can be repurposed, but the process is complex and not always financially viable.
The Alberta Recycling Management Authority has already started to explore recycling options through a pilot project launched in 2020. However, the authority has found it difficult to recycle solar panels and had to send some materials to the United States for processing. They are now working on creating a more localized solution.
Carrocci’s Sunset Renewables is also stepping up to tackle the problem. His company has developed a mobile deconstruction unit to strip damaged panels for parts, such as metals, plastics, and glass. The goal is to repurpose these materials for other industries, such as concrete or asphalt production.
The Future of Renewable Waste Management
Experts agree that addressing the waste created by renewable energy infrastructure is crucial. Wind turbines pose additional challenges because their blades, made of composite materials, are difficult to recycle. While some blades are repurposed into park benches or construction materials, the majority end up in landfills.
Osayuki Osazuwa, CEO of Jeosal Materials Research Corporation, is working on recycling fiberglass from wind turbines to create fiber-reinforced concrete. Montreal-based FibeCycle is making similar efforts. It has developed a process to break down wind turbine blades into fiber-reinforced polymers for use in 3D printing, construction, and even automotive manufacturing.
Governments are beginning to recognize the urgency of this issue. British Columbia is adding solar panels to its recycling regulations, while Alberta is expanding its e-waste pilot program to include solar and wind infrastructure. However, much work must be done to build a cohesive recycling system that can handle the growing waste from renewable energy technologies.
As Canada moves toward its net-zero emissions goals, addressing the environmental impact of renewable energy waste will be critical. The need for sustainable solutions is becoming increasingly urgent, and businesses that invest in recycling technology now stand to benefit greatly in the years to come.
