Fibers are key components of production processes in the textile and apparel value chain and it is crucial to reduce the environmental impact of their manufacture.
The ZDHC Foundation, Amsterdam/Netherlands, released the updated ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines Version 2.0, and its supporting document to continue to push the industry toward increasingly innovative and sustainable fiber production. With this update, the ZDHC MMCF Guidelines V2.0 now include the Responsible Fibre Production Guidelines, Wastewater Guidelines and Air Emissions Guidelines as 3 separate chapters in a single document.
Since expanding the scope of ZDHC’s work to include fiber production with the release of the first ZDHC MMCF Guidelines in 2020, brands and manufacturing facilities producing MMCF have been able to take an aligned approach to emissions control. This includes the recovery of sulfur compounds as part of the inputs, as well as by-products generated during the production process.
Among other changes, this update reflects the expansion of the scope to accommodate viscose filament yarn, lyocell, cuprammonium rayon (Cupro) and cellulose acetate (Acetate). The ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0 provide an aligned approach for included fibers, including defined chemical recovery, wastewater and sludge discharge, and air emission discharge.
ZDHC continues to advocate for the improvement of processes which minimize emissions while also working towards the recovery of input substances and by-products. These dual goals, reduction and recovery, directly address the negative impact of outputs arising from MMCF production.
Along with the ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0, ZDHC has also updated its ZDHC MMCF Guidelines Industry Standard Implementation Approach. This document aims to support the implementation process of the ZDHC MMCF Guidelines V2.0 and features new implementation timelines that assist suppliers in setting their goals to achieve foundational, progressive or aspirational level on the supplier platform.
