- Chemiepark Knapsack hosts multiple recycling-focused companies.
Project Overview
Recycling company matterr is set to build a small-scale industrial depolymerisation plant at Chemiepark Knapsack, specifically in the Hürth section. The facility will have an annual capacity of approximately 10,000 tonnes and aims to advance a fossil-free, circular PET industry. Groundbreaking is planned for 2026.
Innovative Recycling Technology
matterr's patented depolymerisation process targets complex, mixed PET waste streams, such as blended textiles and multi-layer packaging. The process operates under mild conditions at atmospheric pressure, converting waste back into original molecular building blocks. These purified components can then be used in existing polyester production facilities to create virgin-quality products, replacing fossil-based feedstocks.
Strategic Location and Partnerships
The Chemiepark Knapsack site offers integrated infrastructure that supports matterr's operations. The location aligns with the company's focus on promoting the circular economy. Collaboration with YNCORIS, which operates the park, is crucial for transitioning from pilot to industrial scale, leveraging YNCORIS's experience in plant construction and integration.
Ongoing Transformation
Chemiepark Knapsack has been shifting towards a circular economy for several years, with matterr being the third recycling-focused company on site. Other initiatives include LyondellBasell's integrated recycling and downstream processing center for plastic waste and Palurec's beverage carton recycling facility. The park also features a waste-to-energy plant that has been operational since 2009, providing steam from non-recyclable residues for energy supply.
