A 2018 industry expert report commissioned by ZDHC on the production of Man-Made Cellulosic Fibres concluded that restricting chemicals via the ZDHC MRSL approach would not work. The restrictions would halt most MMCF production processes. We would achieve the most impact by collaboratively setting guidance around good chemical management and limits for wastewater, sludge, air emissions, and chemical recovery during fibre production while calling for continued further research into processes for the production of MMCF, using alternative and less hazardous substances.
