Wastewater

This presentation describes the efforts made by HIndustan Zinc Limited at water conservation.

This presentation describes the efforts at environmental management at  JK  Tyres, Kankroli, plant.

This presentation describes the efforts undertaken by ITC Bhadrachalan at water conservation. The company has chosen energy management, environmental & waste management and social & farm forestry as major focus areas for CSR.

Specific processes include recycling/reuse of paper mill back water for dilution of bleached pulp and unbleached tower as well as for pulp slushing; of recausticising plant cooling and sealing water to clarifloculator; reduction in DM water consumption due to increase in process condensate recovery; arresting water piping leakages including fire hydrant piping by clamping; and recycling of paper machine primary clarifier outlet water for miscellaneous uses. Specific water consumption trends show a decrease from 183 cu m/tonne in 1997-'98 to 60.7 cu m/tonne in 2006-'07.

Operating the world's largest barge mounted power plant off the coast of Mangalore, GMR Energy has a specific water consumption of .126 cu m/MWH, which is less than half the national benchmark of .276 cu m/MWH for such plants.

This presentation describes the efforts made by Carrier Aircon, Gurgaon at water conservation. This paper and board manufacturer has brought about a reduction in specific water consumption from 173 cu m/MT of paper (2003-04) to 130 cu m/MT of paper (2006-07), while waste water discharge over the same period has come down from 169 cu m/MT to 103 cu m/MT.

This presentation describes the efforts undertaken by Mico Bosch - Jaipur at water conservation. Water conservation measures taken by this manufacturer of fuel injection pumps for the automotive industry come under the broad heads of reduction in specific water consumption, community partnership & campaigns, and conservation, recycling & auditing.

This, in a larger framework that includes the use of non-conventional energy sources; technology upgradation and increases in usage efficiency; monitoring, auditing and awareness initiatives; resource use minimization and recycling; tree plantation; the minimization of green house gas emissions, vendor/supplier audits and awareness drives for employees and society at large. A zero waste water discharge unit since inception, the plant recycles waste water for both process and gardening needs.

This presentation describes the wastewater management efforts undertaken by Ballarpur Industries Ltd, Yamunanagar, Gurgaon, Haryana. This paper and board manufacturer has brought about a reduction in specific water consumption from 173 cu m/MT of paper (2003-04) to 130 cu m/MT of paper (2006-07), while waste water discharge over the same period has come down from 169 cu m/MT to 103 cu m/MT.

This presentation describes the water conservation efforts made by ITC Limited,  PSPD unit, Kovai, Tamil Nadu. ITC's Kovai unit manufactures paperboard and specialty papers (PSPD). Investments of Rs 30 million in water conservation, Rs.500 million on energy conservation and Rs.150 million on waste utilization have helped this plant achieve many breakthroughs, among them zero effluent discharge and zero solid waste output. 100% of the fly ash from the boiler, sludge from the ETP & plastics from waste is recycled.

The use of waste biomass as the main fuel for the boiler has reduced CO2 emissions by 96,000 tonnes per annum. Under the green belt development activities, vegetation has gone up from 20,000 trees in 2004-'05 to 80,500 in 2006-'07.
