Recyclable Alternative to Latex Carpet Backing
Schmits Chemical Solutions has developed a recyclable alternative to synthetic latex, used for carpet backings. By replacing traditional latex with water-based dispersions, manufacturers can now produce carpets made entirely from a single material, such as polyester, polypropylene, or polyamide, making the carpets recyclable. This development addresses a recycling challenge faced by the flooring industry, as existing carpets often combine multiple materials, making them difficult to recycle. With latex fused irreversibly to other layers, old carpets typically end up in landfills or incineration facilities, contributing to environmental waste in Europe.
Innovative and Sustainable Solutions
Schmits Chemical Solutions’ latest product develops water-based chemistries to enhance the properties of textiles, such as water resistance. The concept for this product was initially inspired by a suggestion from one of their suppliers, who proposed using recycled epoxy polyester powder as an adhesive to bind carpet fibres. After further development by Schmits, these dispersions now offer an alternative that maintains similar quality to latex while being more sustainable.
Testing by the Polymer Science Park confirmed the recyclability of these carpets in 2023. Although these dispersions may initially be more expensive compared to traditional latex, their reduced application weight results in a lighter product, decreasing both production and transportation costs. Schmits’ dispersions require only 300 grams per square metre compared to one kilogram of latex, reducing energy consumption during production and lowering emissions from transportation.
Carpet Recycling in the Netherlands
Currently, the Netherlands lacks a proper system for carpet collection and recycling. Schmits Chemical Solutions is involved in efforts by over thirty industry players, including producers, wholesalers, and waste processors, to make 50% of the flooring chain circular by 2030. By 2026, a functional collection and recycling system for carpets is expected to be in place, boosting circularity in the industry.
