Fibres are an important part of the value chain. Therefore it’s a logical next step for ZDHC Roadmap to Zero Programme to include fibre production processes and their raw materials. MMCFs are produced from cellulose sources using hazardous chemicals. Within the production process of viscose and modal, particularly where that’s not an integrated (closed loop) process, chemicals react with the cellulose. This creates by-products, which can be released into the air, water and soil.
