Having an ISO-14001 Environmental Management Systems (EMS) will help and enhance a firm's economic performance and at the same time will improve its environmental performance. The benefits of ISO-14001 lie in cost savings through energy consumption, raw material input, waste management, environmental impact reversal as well as an improved public image.
The pulp and paper industry is water intensive among major chemical process industries. Water is the medium where all the pulp and paper making process are carried out and used as vehicle to transport the pulp in the mills from one unit operations to another. A major fraction of water used becomes contaminated during various processes.
Amongst all the greenhouse gases (GHG) present in the atmosphere methane has assumed considerable significance. Atmospheric concentration of methane has almost doubled after industrial revolution. It contributes to 20% of total GHG effect. In industrial countries, 15% of total GHG contribution comes as methane emission and it is expected to contribute to
THE dyeing and washing unit owners will observe a one-day token fast here on Wednesday urging the State and Central governments for sanctioning 75 per cent subsidy for 20 common effluent treatment plants (CETPs), which were established at a cost of Rs 800 crore, because of the lack of a response from the government following their indefinite strike.
Patancheru, near Hyderabad, India, is a major production site for the global bulk drug market. Approximately 90 manufacturers send their wastewater to a common treatment plant in Patancheru. Extraordinary high levels of a wide range of pharmaceuticals have recently been demonstrated in the treated effluent. As little as 0.2% of this effluent can strongly reduce the growth rate of tadpoles, but the underlying mechanisms of toxicity are not known. To begin addressing how the effluent affects aquatic vertebrates, rainbow trout (Oncorhynchus mykiss) were exposed to 0.2% effluent for 5 d.
The Nagaon Paper Mill, a public sector pulp and paper mill, a unit of Hindustan Paper Corporation Limited, is located at
Jagiroad, Morigaon district, Assam and generates about 448 tonnes
of lime sludge per day as solid waste. Instead of marketed lime,
An ecofriendly method, involving mild organic acids to hydrolyse delimed tannery fleshings (TF), has been developed. Combination of formic acid and propionic acid (1:1) was employed to obtain hydrolysates with higher degree of hydrolysis (DH). Better antioxidant properties were obtained by response surface method (RSM) using a factorial design.
The demand for biofuels has recently increased because of rising prices of fossil fuels and diversification of energy resources. As a result, the demand for sugarcane and corn has been increasing, not only for food production, but also as sources of energy.
The sugarcane industry is one of the major water consuming industries. They play a major role in national economical development programmes. India is the second largest producer of sugar in the world.
