has raised $6.4 million in a B series funding round. The company will use the money to begin scaling up its process for converting waste plastics into pyrolysis oil. The funding round was co-led by Transitions First (T1ST), an international industrial deep tech seed-stage venture capital fund, and Lummus Technology, a global provider of process technologies and energy solutions.

The funding will be used to scale production of its continuous microwave-assisted pyrolysis (CMAP) technology and to expand the company’s executive team. Following the investment, Leon de Bruyn, president and CEO of Lummus Technology, and Marianne Abib-Pech, managing partner, T1ST, are joining the company's board of directors.

“We're accelerating plastic circularity with our technology,” says Resynergi CEO Brian Bauer. “By diverting plastic from our landfills and oceans we’re on a mission to protect human health and our environment. This round of funding and the additions to our board of directors underscores our position as a trusted solution partner in the recycling ecosystem for those who view hard-to-recycle plastic as a resource to meet the outsized market demand for products that incorporate recycled plastic. With the support of our investors and partners, we’re on a trajectory to execute our next phase of growth to help communities realize the promise of recycling their plastics while creating new sustainable materials that reduce dependence on fossil-based resources.”

Resynergi's advanced recycling technology can utilize high-density polyethylene (HDPE), low-density PE (LDPE), polypropylene (PP) and polystyrene (PS) waste plastics to create pyrolysis oil. The current 1-ton reactor converts 1.25 ton/day of postconsumer and postindustrial plastic to oil. By placing 4 CMAP reactor units on a skid, Resynergi plans to convert 5 tons per day and scale production of its reactor units-on-a-skid model across the U.S.

“In many cities, it's economically challenging to collect more than 50 tons of plastic waste per day,” Bauer says. “Our technology is highly efficient within the 20 to 50 tons per day processing window, making it a game-changer for communities.”
