DePoly inaugurated its Showcase Plant in Monthey, Switzerland on July 6 and 7. As the first depolymerization facility of its kind and scale in Switzerland, this industrial Showcase Plant represents a milestone in the company’s growth and its journey towards commercialization.

‍The Showcase Plant has a nominal capacity of around 500 tons feedstock input per year. Beyond production, it will serve to optimize the process, qualify raw materials with industrial customers, and prepare for the deployment of DePoly's first commercial plant.

DePoly’s depolymerization technology

Unlike traditional recycling, which progressively degrades material quality with each cycle, DePoly's technology breaks PET down into its original chemical components, enabling it to recreate virgin-quality raw materials with no loss of performance and suitable for all PET applications.

DePoly's process is based on light-activated chemical depolymerization, capable of processing PET in under 60 minutes, without the need for high temperatures or added pressures. This approach recovers the material's original monomers, which can be directly reused in existing industrial processes with no loss of quality.

Its strength lies in its versatility. It handles a wide range of waste streams that are poorly served by conventional recycling: food packaging, polyester textiles, complex films, colored or contaminated materials. The recovered raw materials find applications across sectors as varied as packaging, textiles, automotive and electronics.

Building a foundation for commercial scale up

The Showcase Plant is above all a blueprint for commercial scale up. It allows DePoly to demonstrate its technology at industrial scale, qualify its products with customers, and gather the operational data needed to deploy its future commercial facilities.

The lessons learned and process built at the Monthey site will feed directly into the development of DePoly's first commercial plant — a pioneering facility unprecedented at this scale, already in preparation, with its location to be announced in the first half of 2027. Targeting a capacity of 50,000 tons per year, this plant will represent a decisive step toward the large-scale deployment of DePoly's technology.

Beyond this next milestone, DePoly has already established itself for international growth with commercial projects and strategic partnerships in key markets around the world. The long-term goal: to make material circularity an industrial reality on a global scale.
