NMMO - N-METHYLMORPHOLINE OXIDE
NMMO is the only chemical solvent used in the production of lyocell. The chemical and the effluent from the production process is considered nontoxic and easily regenerated. As we will see soon, the NMMO solution for making Tencel is 99% recyclable. Of the 1% waste, that waste can be easily treated using biological wastewater treatment methods. The effluent contains “only small amounts of organic chemicals and salt, mainly sodium sulphate”. Overall, the environmental of NMMO are considered low.
