Eastman combining molecular recycling with thermal battery technology for clean energy

Eastman’s molecular recycling facility in Texas will use cutting-edge technology in thermal batteries

  • By ICN Bureau | June 17, 2024

Eastman took another step forward by announcing to build a second molecular recycling facility in Longview, Texas. The project will now put Eastman out in front in the search for alternative, clean energy sources.

Powered by the selection to negotiate an award of up to US$ 375 million from a U.S. Department of Energy’s Office of Clean Energy Demonstrations (OCED) program targeting climate change, Eastman will use a relatively new energy technology — thermal batteries — on a scale never seen before.

Eastman’s choice of thermal battery technology for zero-carbon process heat, combined with efficient and high-yield molecular recycling technology, will address two global challenges at once.

“This can be a game changer for addressing both the plastic waste crisis and the climate crisis at the same time,” said Sandeep Bangaru, vice president of Eastman’s circular platform. “We’re taking a leadership role in building the largest thermal battery project to date in our industry.”

The Longview facility will have the capacity to process approximately 110,000 metric tons of hard-to-recycle plastic waste, and both the Kingsport and Longview plants will put Eastman on the path to achieving ambitious goals of recycling 250 million pounds of plastic annually by 2025 and double that volume by 2030.

The Longview project is part of Eastman’s commitment to invest more than US$ 2 billion in molecular recycling facilities that process hard-to-recycle plastics. Eastman began operating the world’s largest material-to-material molecular recycling facility in Kingsport, Tennessee, earlier this year.

In addition to familiar forms of renewables, including on-site solar, Eastman will deploy a recent innovation that produces zero-carbon heat: thermal batteries. This technology could be a breakthrough for powering industry with cleaner energy.

Eastman has been collaborating with Rondo Energy to deploy thermal batteries for the project. Rondo Heat Batteries (RHBs) are essentially modular units containing thousands of tons of brick and coils of metal, much like those in the toaster on your kitchen counter. RHBs transform intermittent renewable power — in Eastman’s case, much of it from new, on-site solar — into heat in excess of 1000 degrees Celsius. The brick “batteries” can store massive amounts of heat for up to 24 hours, with very little loss.

By incorporating thermal batteries fed by renewable energy, Eastman will be able to recycle hard-to-recycle polyester waste and produce new, recycled materials with up to 90% fewer greenhouse gas emissions than materials produced with fossil feedstocks. PepsiCo has already signed a contract to use Eastman Renew materials from the Longview facility to create more sustainable packaging with a much lower carbon footprint.

John O'Donnell, CEO of Rondo, said the project demonstrates how collaboration can deliver a multiplier effect with cutting-edge technologies.

"Our work with Eastman illustrates how innovation and collaboration are essential to address great world challenges," O'Donnell said. "Years of innovation and development by Eastman in molecular recycling combined with Rondo's expertise in thermal batteries have delivered a moment where these technologies can be deployed together at large scale. “

Neil Brown, an Eastman engineer who is a leader in assessing renewable energy, said thermal batteries could be a critical innovation for decarbonizing industry.

“This can be a true game changer for providing low- or zero-carbon power for industrial processes,” Brown said. “Anywhere there are great needs for process heat — and Eastman uses a lot of heat to power our processes — thermal batteries can be a solution because you’re able to store heat for so long with so little loss. Another plus of building this new facility at an existing site is that if we run into challenges as we’re integrating the new thermal technology, we have backup steam and power systems in place to allow continued operations.”

In addition to the clean energy and circular economy advantages, there will be tangible benefits for the community. Eastman has committed a US$ 20 million investment for a comprehensive community benefit plan that is part of the DOE award. The overall Longview project will create 1,000 temporary construction and trade jobs and 200 full-time jobs when construction is complete in the 2027 timeframe.
