DePoly has inaugurated its Showcase Plant in Monthey, Switzerland—the country’s first depolymerization facility of this kind and scale. The site marks a key step toward commercialization of DePoly’s technology, which chemically breaks PET back into its building blocks for reuse, avoiding the quality degradation seen in traditional mechanical recycling.

What impact do you think chemical depolymerization plants like this will have on PET recycling supply chains and brand adoption in your region?

DePoly (Sion, Switzerland) inaugurated its Showcase Plant in Monthey on July 6–7. The first depolymerization facility of its kind and scale in Switzerland, this industrial Showcase Plant represents a major milestone in the company’s growth and its journey toward commercialization. Unlike traditional recycling, which progressively degrades material quality with each cycle, DePoly’s technology breaks PET […]

Curious what your feed spec looks like: how much PVC/PLA, dyes, and multilayer barrier can you tolerate before yields or catalyst life tank? On the maintenance side, how are you handling adhesive/label gunk and fines - inline melt filters and decanters, or scheduled reactor cleanouts - and what OEE are you targeting once the alarms settle down?

From our trials with PET depoly at pilot scale, the pain point wasn’t the chemistry but front-end prep: removing label adhesives, multilayer films, and PVC fines to keep OPEX in check. What contamination levels can your process tolerate for common PSA adhesives and non-PET polymers, and what purity specs are you hitting on TPA/EG to enable bottle-grade re-poly?
