Risk of sourcing from Ancient and Endangered Forests

Actively engaging suppliers – no known high risk

Tangshan Sanyou completed and released the results of their second CanopyStyle Audit in September 2020. The audit confirmed that Tangshan Sanyou had taken immediate action to remove all known high risks in their supply chain. Through their policy implementation and audit process, the company has taken meaningful actions to improve transparency and to help fill information gaps, when incomplete raw materials sourcing information was provided by some of their dissolving pulp suppliers.

While the audit did not fully confirm low risk, the company is engaging its supply chain partners to gather sourcing information to assess and is actively working to address sourcing risks including requiring suppliers to attain Forest Stewardship Council (FSC) certification and implement science-based conservation planning of Ancient and Endangered Forests through supply contracts.

Key Improvements Required

  • Publish the names and locations of all suppliers.
  • Accelerate the of use of Next Generation Fibre Solutions in order to meet or exceed the aspirational targets outlined in the Next Generation Vision for Viscose in all its product lines.
  • Continue to engage dissolving pulp suppliers, with Canopy’s support, to confirm low risk and/or risk mitigation measures and work towards elimination of all risk.
  • Where virgin fibres are used and they are not coming from key priority Ancient and Endangered Forests, procure higher volumes of FSC 100% certified inputs from sources that have achieved FSC Forest Management certification on the ground.
  • Provide letters to support conservation solutions in key priority Ancient and Endangered Forests.

Areas where the company is showing leadership

Sanyou has shown continuous leadership over the last number of years, as they have:

  • Commercial production of viscose staple fibre made from 50% post-consumer recycled cotton textiles.
  • Agreed to work with Canopy in a formal process to proactively avoid risk of sourcing from Ancient and Endangered Forests when looking to expand their operations or consider new sources.
  • Entered into a long-term partnership with Renewcell which has enabled the innovator to secure investment and open a new mill.
  • Engaged supply chain partners to participate in large-scale conservation solutions in Canada’s Boreal Forest.
  • Signed on to the Next Generation Vision for Viscose, and actively promotes its collaboration with Canopy and the use of Next Gen fibres.

Number of viscose, lyocell and dissolving pulp mills + location and production volumes

Tangshan Sanyou now produces a viscose staple fibre made from 50% post-consumer recycled content dissolving pulp called ReVisco. With pulp supplied by Renewcell, ReVisco was launched into the marketplace in 2020.

The Tangshan Sanyou Group Company Limited owns two viscose mills and one dissolving pulp mill named:

  • Tangshan Sanyou Xingda Chemical Fiber Co., Ltd.
  • Tangshan Sanyou Yuanda Fiber Co Ltd.

Together these mills have a combined viscose capacity of 860 000 tonnes, and 500 tonnes of lycoell.

Tangshan Sanyou Group owns the subsidiary Dongguang Pulp Co. Ltd – a Chinese dissolving pulp mill which uses cotton linter as raw material. The annual capacity is 170 000 tonnes.
