TERSUS Carbon Dioxide (CO₂) Technology Platform
CO₂ cleaning and processing platform
Brand: TERSUS
TERSUS CO₂ technology platform for textile and specialty material processing.
Features
- Process development with gaseous, liquid and supercritical CO₂ phases; near-production-scale trials on platforms of various sizes. The specific model/capacity is not indicated on this page.
- CO₂ is purified and recirculated; the manufacturer states it uses gas that is a by-product of other industries.
- Research areas: a waterless process from raw wool to yarn with a lanolin by-product; lignin breakdown/fiber separation in hemp; recycling of down and feathers.
- Waterless initial and repeat application of DWR water-repellent coating, without conventional high heat.
- Removes grease and dirt from medical sutures/implants; cytotoxicity criteria are reported to be met prior to sterilization.
- Collaborations noted by the source: Downlite raw down process, The Renewal Workshop, The North Face Renewed, LION TotalCare RedZone, IDFL recycled down certification. As calendar markers were jumbled in the source HTML, unconfirmed dates have not been included.
