Leading MMCF producer Tangshan Sanyou has launched a new pilot testing facility to accelerate circular innovation in viscose fibre production. The 10-tonne pilot line focuses on a solvent-based process that transforms waste cotton textiles directly into high-quality ReVisco™ fibres, marking a pivotal step in scaling recycled MMCF.
This milestone adds to Tangshan Sanyou’s growing investment in Next Generation (Next Gen) fibre solutions, aligning with its long-standing sustainability strategy. Since 2018, the company has integrated various textile waste streams into its fibre offerings, helping to drive industry-wide shifts toward circularity and reduced environmental impact.
Key developments include:
-
First MMCF producer to incorporate CIRCULOSE® at a 30% blend in black viscose and coloured fibre variants.
-
Ongoing partnership with CIRCULOSE®’s new owners as their Sweden-based mill reopens.
-
Integration of Södra’s OnceMore® recycled cotton pulp at a 20% blend in viscose and modal fibres.
-
Scalability readiness to produce 200,000 tonnes/year of ReVisco™.
-
Expansion into ReVisco™ lyocell using recycled inputs.
-
Trials using hemp and Juncao as feedstocks.
“With this test facility, we are deepening our commitment to circular fibre production,” said a company spokesperson. The move was also welcomed by environmental NGO Canopy. Nicole Rycroft, Canopy’s Founder and Executive Director, stated:
“Tangshan Sanyou’s consistent leadership in reducing forest-based inputs is significant. This new pilot facility supports the global shift toward commercial-scale Next Gen MMCF.”
With a production capacity of 808,000 tonnes per year, Tangshan Sanyou has been a Canopy partner since 2016 and holds a Dark Green Shirt rating in Canopy’s 2024 Hot Button Report, signalling no known risk of sourcing from Ancient or Endangered Forests.
