Several pioneering companies are at the forefront of recycling end-of-life solar panels, wind turbines, and lithium-ion batteries, supporting the development of a circular economy in the climate tech sector.
The continuous expansion of wind and solar energy, coupled with the increasing adoption of electric vehicles (EVs), plays a vital role in the United States’ pursuit of reducing reliance on fossil fuels, curbing carbon emissions, and addressing climate change.
However, as these renewable energy industries grow, a substantial amount of waste is anticipated from retired components. In response, a number of forward-thinking startups are revolutionizing the renewable energy sector by establishing a sustainable and profitable circular economy that recovers, recycles, and reutilizes essential components in climate tech innovations.
According to the U.S. Energy Information Administration (EIA), wind and solar energy collectively accounted for 13.6% of utility-scale electricity generation in the previous year, and these figures are expected to rise further as renewable energy continues to scale up. Recognizing this trend, leading utilities across the country are already accelerating their transition to renewable energy sources.
Simultaneously, the sales of all-electric vehicles in the U.S. have experienced substantial growth. In 2022, electric vehicles captured 5.8% of the total 13.8 million vehicles purchased by Americans, up from 3.2% the previous year. The Environmental Protection Agency’s proposed tailpipe emissions limits and power plant rules could push electric vehicle sales to capture a 67% market share by 2032, further expediting the shift to clean energy.
One notable example of a company addressing the waste issue in the climate tech sector is an innovative startup founded in Oakland, California last year.
This company has established a recycling facility in Odessa, Texas, where it effectively extracts 95% of materials from end-of-life solar panels, reintegrating them into the supply chain.
By selling recovered silver, copper, glass, silicon, and aluminum, this company contributes to the circularity of solar panels, preventing them from being discarded in landfills.
With an average lifespan of 25 to 30 years, the responsible disposal and recycling of solar panels are imperative, considering that over 500 million panels have already been installed nationwide.
If not properly addressed, it is estimated that between 2030 and 2060, approximately 9.8 million metric tons of solar panel waste will accumulate.
Presently, about 90% of end-of-life or defective solar panels are disposed of in landfills due to the lower cost involved. However, the market for recycled solar panel materials is projected to experience exponential growth in the coming years, potentially reaching over $2.7 billion by 2030 and meeting 30%-50% of solar manufacturing needs in the U.S. by 2040, according to the National Renewable Laboratory.
In the wind energy sector, the recycling challenge lies in decommissioned wind turbines.
