DePoly to launch PET-to-raw-material showcase recycling plant

DePoly, a winner of the 2024 Top 100 Swiss Startup Award, has announced the upcoming launch of a 500-tonne-per-year showcase plant in Monthey, Switzerland this summer. The facility will demonstrate the company's proprietary process that converts PET and polyester waste into virgin-quality raw materials.

DePoly’s technology has already demonstrated its commercial impact through collaborations with some of the world’s leading companies—not only in fashion, like Odlo, but also in cosmetics and the broader consumer goods industry, including innovators such as PTI.

Through these partnerships, DePoly has validated the quality of its recycled monomers by transforming PET waste into new bottles, high-performance textile fibers, and cosmetic packaging.

“The upcoming showcase plant validates our roadmap to creating a truly circular plastics market. Following our pilot and showcase plant, our next goal is to scale our operations to industrial size with a first of a kind commercial plant based on our technology,” said Samantha Anderson, Co-founder & CEO of DePoly.

DePoly is planning to build a commercial plant in 2027 that will process significantly larger volumes of PET and polyester waste. To further accelerate this expansion, the company has secured a total of US$23 million in seed funding with MassMutual Ventures.

MassMutual Ventures joins existing investors, including Founderful, ACE & Company, Angel Invest, Zürcher Kantonalbank, BASF Venture Capital, Beiersdorf Venture Capital, and Syensqo.
