Afforestation
The bare landscape of the Dewas Factory complex has metamorphosed into a verdant landscape with the systematic planting of over 200, 000 trees since 1975.
Pollution Control
Various international experts and agencies, including the United Nation's Industrial Development Organisation, have applauded the Indian leather industry's performance on the environment protection front.
The manufacturing process for leather generates solid and liquid waste and some air pollution. Our Leather Finishing Unit at Dewas generates approximately 150m3 of effluent per day, approximately 2 MT of solid waste in terms of leather dust and trimmings and minor amounts of chemical vapours on the shop floor.
In 1998-99 the internationally accredited Central Leather Research Institute carried out an Environmental Impact Assessment study in a 10 km radius around the leather factory at Dewas, testing the ground water, effluent emission and air pollution and the study showed that the leather factory does not create any adverse impact on the surrounding environment.
Effluent Treatment
Our elaborate liquid waste treatment plant at our Dewas manufacturing facility is one of the best in the industry. The treated effluent quality has remained close to the demanding norms Madhya Pradesh Pollution Control Board.
The effluent treatment system, processes 150cu. meters of effluent per day. The treated effluent has analysis values for BOD, COD, pH value Chromium, etc., which are within permissible limits for use for land irrigation purposes.
The treated effluent water is used for horticultural purposes within the complex, is stored for fire fighting emergencies, and is recycled for process needs. This is also a part of our water conservancy efforts. The quality of treated effluent has made it possible to develop pisciculture in our treated effluent.
The ground water quality has been monitored and tested over the years. It shows no appreciable change, and this is also supported by the Environmental Impact Assessment.
Water Conservation
Besides conserving water by using treated water for maintaining the mini forest within the complex, treated water is re-cycled for process needs within the factory. At present, 40% replacement of fresh water need at the shop floor is being worked on, with good prospects of close to 100% replacement in the near future.
Other methods of conserving water include rain water harvesting from the rooftops of buildings, collection of rain water in large wells scattered over the 100 acre plot, trenches dug around the plot for guiding rainwater into the ground. The water table in the area has actually risen due to the afforestation and water conservation practices within the complex.
Air Pollution Control
To handle the air pollution factor we have installed 9 tall chimneys of 1M diameter and 16M height to take care of spray booth vapours. The Air Pollution level remains below the regulatory norms.
Energy Conservation
For the sake of fuel economy and in order to reduce air pollution, Tata International has installed the largest solar panel water heating systems in the state of Madhya Pradesh, with an array of 711 flat plate collectors, for pre-heating 50 M3 of water per day to 80°C to be used as boiler feed water, which has led to a reduction of approximately 15% in coal consumption with consequent drop in emissions.
