To improve the efficiency of processes to reduce consumption and reuse of water multiple times, Grasim Industries Limited has adopted state-of-the-art novel technologies such as membrane processes, which could clean up and recycle the wastewater.
In last few years, Grasim-Nagda (MP) has taken the significant step of committing to zero liquid discharge (ZLD). Work is in progress and will be completed in 2021.
Notably, the Nagda plant will be the first viscose unit in the world to achieve ZLD.
Dilip Gaur, MD of the company said, “Nagda plant is leading the way with the VSF business being the lowest water consumer globally. The plant also meets water needs of the entire city, railway and irrigation needs of the farmers through the 30 billion litre storage capacity built by Grasim.”
“Grasim-Nagda plant makes large range of dope-dyed fibres, which are dyed at the time of manufacturing the fibre itself. This technology consumes 50 per cent less chemicals and does not require any additional water for colouring, reducing the water requirement in the post-fibre stage for colouring to zero,” said K. Suresh, Unit Head, SFD Nagda.
In other development, Grasim Industries has incorporated a joint venture company, viz., ‘Birla Advanced Knits’ for undertaking knits manufacturing business in partnership with Century Textiles and Industries. Both organisations will have equal stake in the new venture.
