Recycling – Teijinconex® circularity roadmap
Teijin Aramid is actively collecting end-of-life products containing meta-aramids from the protective apparel value chain. In order to make this happen, we work with global circular partners. After sorting, cleaning, and cutting, the aramids are recycled through three innovative routes.
Route 1 Mechanical recycling
We focus on recovering meta-aramid materials from production waste and end-of-life products. The recycled meta-aramids are reused in staple fiber blends with virgin Teijinconex®.
Route 2 Physical recycling
We dissolve the collected end-of-life aramid (Teijinconex®) with our virgin polymer. This is then spun into fibers that contain a significant amount of recycled content while retaining the same properties as 100% virgin fiber.
Route 3 Chemical recycling
Chemical recycling, also known as depolymerization, involves breaking down the aramid polymer molecules into small chemical building blocks. At our polymerization factory, we reintroduce these recovered monomers to produce new Teijinconex®. Another option is to use bio-based raw materials, or recycled plastic produced by our suppliers, as building blocks.
The ultimate goal is to replace all fossil-based resources with renewable ones.
Building trust through expertise
Over the years, we have invested in facilities and talent that have made us the industry authority on the application of aramid materials. We believe that sustainable value creation and cost awareness are critical success factors for both ourselves and our customers. This means making products that match customers’ needs as efficiently as possible while ensuring that they meet the required performance level.
Creating partnerships
Teijin Aramid is constantly improving products and working towards innovative solutions with our partners at our R&D locations. Our wide knowledge in testing, blending, and fabric development means we have unique, hands-on experience in complex projects that deliver real value to end users. Partnerships are handled with professional discretion.
Make informed choices with the Customer Benefit Model
Teijin Aramid has focused on an eco-efficiency methodology, which has been translated into a concrete model: the Customer Benefit Model (CBM). Together with the customer or end user, Teijin Aramid can use the CBM to calculate the effect of applying aramid, both in terms of financial cost savings and the reduced impact on the environment. Our official certification with TÜV Rheinland LGA Products GmbH gives us a model that is internationally recognized and which, in collaboration with customers, Teijin Aramid can apply to all relevant aramid applications.
The CBM empowers the customer to make an informed decision: It’s a tool that provides data and transparency regarding costs and environmental burden.
