Closed Loop Partners Invests $10 Million to Scale GreenMantra’s Molecular Recycling

According to a statement released by Closed Loop Partners, it has committed more than $10 million through its Closed Loop Infrastructure Group to GreenMantra Technologies, a Canadian molecular recycling firm, to expand its capacity for converting hard-to-recycle plastics into high-value materials. The investment is part of the Closed Loop Infrastructure Group’s ongoing efforts to support technologies that advance plastics circularity across North America.

It is reported that this financing will fund new equipment at GreenMantra’s Brantford, Ontario facility, enabling the company to increase output of specialty waxes and polymer additives derived from polyethylene (PE) and polypropylene (PP). This is the third loan provided by the Infrastructure Group to GreenMantra over the past decade, reflecting long-term confidence in the company’s technology and business model.

According to public information, GreenMantra, established about 15 years ago, has commercialized a patented molecular recycling process that transforms difficult-to-recycle plastics into materials widely used in industries such as roofing and road paving. The company’s depolymerization technology is reported to be more energy-efficient than conventional methods, while handling plastics often unsuitable for mechanical recycling. Such approaches are considered essential for tackling the growing volume and diversity of global plastic waste.

Jennifer Louie, Managing Director of the Closed Loop Infrastructure Group, said, “GreenMantra demonstrates a resilient business model, a technically proven process and a clear path to scale. We look forward to continuously supporting the company as they further their mission to valorize plastic waste otherwise destined for landfills.”

According to Domenic Di Mondo, CEO of GreenMantra, “With the support of Closed Loop Partners and other investors, we’re now expanding commercial capacity for our products to meet growing demand—transforming even more recycled plastics into high-performing materials, and keeping valuable resources in circulation.”

Industry observers note that molecular recycling is becoming a critical complement to mechanical recycling in North America, especially as supply chain volatility and regulatory pressures increase. By converting plastics that would otherwise be landfilled into economically valuable products, technologies like GreenMantra’s contribute to corporate sustainability goals and the broader transition to a circular economy.

It is reported that the loan comes from the Closed Loop Infrastructure Group’s Circular Plastics investment strategy, backed by major industry players including Dow, LyondellBasell, NOVA Chemicals, Chevron Phillips Chemical, and Sumitomo Mitsui Banking Corporation. With this financing, GreenMantra is expected to raise its specialty material output by approximately 50%, while pursuing geographic expansion and further advancing sustainable plastics solutions across North America.
