Lenzing’s Tencel fibre is perhaps its most widely known, while the company also produces lyocell and viscose fibres that are carbon zero, or blended with upcycled cotton waste, to name a few. Lenzing was awarded a platinum EcoVadis CSR rating in 2021, putting it in the top 1% of assessed companies. So while no company is perfect, you will find it hard to source better plastic-free fabrics at scale today.
