Resynergi secures $18M Series B funding for plastic recycling technology

Resynergi, a developer of modular advanced plastic recycling technology headquartered in Rohnert Park, California, has announced the raise of $18 million in Series B extension funding led by Taranis, the investment and asset management company of Perenco Group.

Resynergi says this funding round will allow it to commission its first commercial-scale site, equipping the company to address what it calls the “outsized demand” for sustainable, circular plastic resin.

“Sustainability goals and extended producer responsibility laws are fueling a surge in demand for efficient and reliable plastic recycling solutions,” Resynergi CEO Brian Bauer says. “We’re fortunate to have mission-aligned partners like Taranis, Lummus Technology, Transitions First and a committed bench of existing investors that recognize the market opportunity in front of us. We’re committed to turn on the first of many commercial sites while enhancing the value chain we’ve created to divert plastic from our landfills and oceans and convert it back into its molecular building blocks for reuse. Together, we’re reducing the strain on our environment and helping to mitigate the global plastic crisis."

Resynergi says Taranis is known for backing cutting-edge technologies and is making a significant commitment to Resynergi’s vision for a more circular and low-carbon future. The company says Taranis’ investment will empower it to expand operations for its first commercial-scale site, positioning the company to play a key role in addressing what it claims is an estimated 70 percent global growth in plastic scrap by 2050.

“We are proud to be part of Resynergi’s mission to lead in plastic waste transformation,” Taranis Investment CEO Emmanuel Colombel says. “Their scalable solution not only reduces CO₂ emissions but produces high-quality recyclable materials, making them a key player in the global effort toward a circular economy. This investment reflects our commitment to accelerating the transition to a circular economy.”

Following the successful investment, Katherine Corrigan of Taranis Carbon Ventures will join the Resynergi board of directors. Resynergi notes that Ilya Aranovich, vice president of corporate strategy at Lummus Technology and Marianne Abib-Pech, managing partner at Transitions First and the former global chief financial officer of Shell Aviation, remain on the company’s board.

Resynergi’s proprietary continuous microwave assisted pyrolysis (CMAP) technology, branded Resynergi Modules and supplied by partner Lummus Technology, feature a modular design that allows for rapid scaling, enabling material recovery facilities (MRFs) and businesses to efficiently process up to 50 tons of plastic scrap per day. With a smaller footprint and fast conversion times, Resynergi says its product offers a cost-effective and environmentally friendly alternative to traditional recycling methods.

The company says it works with recycling organizations to secure and transform hard-to-recycle plastics, diverting millions of pounds of plastic from landfills and oceans.
