Charter on Corporate Responsibility for Environmental Protection Dyes and Dye Intermediates

Wastewater Management

1. Efforts will be made for conservation of water, particularly with a target to have consumption less than 8, 12 and 15 m3/tonne of urea produced for plant based on gas, naphtha and fuel oil, respectively. In case of plants using Naptha and Gas both as feed stocks, water consumption target of less than 10 m3/tonne will be achieved. An action plan for this will be submitted by June 2003 and targets will be achieved by March 2004.
   
   
2. Use of arsenic for CO2 absorption in ammonia plants and chromate based chemicals for cooling systems, which is still continuing in some industries, will be phased out and replaced with non-arsenic and non-chromate systems by December 2003. In this regard, action plan will be submitted by June 2003.
   
   
3. Adequate treatment for removal of oil, chromium (till non-chromate based cooling system is in place) and fluoride will be provided to meet the prescribed standards at the source (end of respective process unit) itself. Action plan will be firmed up by June 2003 for compliance by March 2004.
   
   
4. Proper and complete nitrification and de-nitrification will be ensured, wherever such process is used for effluent treatment, by September 2003.
