Redwood Materials has announced a collaboration with Ultium Cells LLC, a joint venture between General Motors Co. and LG Energy Solution, focusing on the recycling of battery scrap from manufacturing sites in Warren, Ohio, and Spring Hill, Tennessee.
As part of the agreement, Redwood will handle all scrap materials from Ultium’s operations in both Ohio and Tennessee. Annually, this amounts to approximately 10,000 tons of scrap. Redwood points out that typically, 5% to 10% of materials in battery factories end up as scrap.
The recycling process managed by Redwood will convert these scraps back into usable battery materials, which are then supplied back to battery cell manufacturers, thereby creating a closed-loop system that enhances sustainability in battery production.
The initiative is set to utilize Redwood’s advanced recycling technologies, which are designed to be more energy-efficient and use less water compared to traditional methods, resulting in lower CO2 emissions.
This approach not only supports environmental sustainability but also aligns with global regulatory pushes for reduced greenhouse gas emissions. Automakers worldwide are ramping up EV production, which in turn fuels the demand for more sustainable battery solutions and necessitates increased recycling capacities.
Redwood’s CEO, JB Straubel, who co-founded Tesla Inc., is at the forefront of this initiative. His background and experience in the EV sector are crucial in driving innovations in battery recycling. The broader industry, including startups like California-based Sila, is also moving towards more sustainable battery solutions.
Sila, led by former Tesla engineer Gene Berdichevsky, plans to supply advanced battery materials to Panasonic’s U.S. plants post-2025, promising enhanced range and reduced charging times for EVs.
Additionally, Tesla’s recent investment of $3.6 billion into a Nevada facility for developing a new, larger type of battery cell underscores the accelerating pace of innovation and capacity expansion in the battery sector.
