Clariant: recycling of carpets
Although the vast majority of carpets today are made of recyclable woven or tufted materials, most textile flooring still ends up in landfill or end-of-life incineration. This is largely due to the traditional use of a latex, water-based backing which cannot be removed from the pile fibers and creates a difficult-to-recycle material mix.
In a joint collaboration between the specialty chemicals company Clariant International Ltd., Muttenz/Switzerland, and the Fraunhofer Institute IVV, Freising/Germany, the recycling CreaSolv process has been developed achieving zero waste targets. Recyclable Licocene Performance Polymers (LPP) from Clariant deliver the benefits of a hot melt carpet backing. By replacing latex with a 100% solid content backing solution, water and the associated drying process can be fully avoided, adding up to energy savings of up to 80%, as shown in production trials with carpet manufacturers. As a result, no contaminated waste water occurs. The propylene based LPP can be recovered with at least 90% of its virgin quality for re-use via the CreaSolv recycling technology, ensuring a cradle-to-cradle approach. Now, flooring textiles can be recovered and integrated back into production or downcycled into other applications. The whole process provides the missing link for the industry to design fully recyclable carpets.
Starlinger: closed loop system for big bags
At the leading plastics exhibition K 2019 from October 16-23, 2019, in Düsseldorf/Germany, the producer of machinery and complete lines for woven plastic bag production Starlinger & Co. Ges.m.b.H., Vienna/Austria, will present a sustainable closed loop system for big bags made from woven polypropylene.
Worldwide, more than 380 million 4-loop big bags (FIBCs – Flexible Intermediate Bulk Containers) are sold every year; this equals an annual recycling potential of approx. 800,000 tons of material.
With circular packaging, Starlinger will introduce a concept for a closed loop for big bags that begins with polypropylene granulate and leads back to polypropylene regranulate (rPP) through the process steps production, usage, recovery, and recycling.
Freudenberg: sustainability campaign
Increasing numbers of consumers are weighing sustainability when making their purchasing decisions. With a new campaign, the manufacturer of technical textiles Freudenberg Performance Materials Holding SE & Co. KG, Weinheim/Germany, is presenting examples of how the company is helping to make the fashion industry more sustainable.
The campaign concept hast 2 elements: fact-based posts on LinkedIn, Facebook, Twitter, and WeChat are complemented by interesting articles on the company's website.
Freudenberg Performance Materials belongs to the forerunners in the recycling of PET bottles and is currently one of the largest recyclers in Europe. The company recycles 7 million PET bottles/day.
