A number of studies have already been carried out for the metal analysis of paper mill effluents which are generally using wood and non-wood (bamboo, baggase etc.) as fibrous raw material for paper manufacturing process. This study deals with a paper mill which is using cotton comber and cotton liner as raw material for paper manufacturing process.

To meet present day stringent pollution control norms, there was a high stress on paper mills to deliver highest quality work with low operating cost within the budgeted limitations. Keeping this in view, biological treatment procedure is adopted. Use of blend of bacterial colonies in place of conventional urea & DAP dozing have proven to be cost effective solution.

Closing loops by intercompany recycling of by-products is a core theme of industrial ecology (IE). This article considers whether industrial recycling networks or industrial symbiosis projects can be used as a starting point for much broader intercompany cooperation for sustainable development.

The strong interaction of the steel industry and the environment is related to the large volumes of matter that are handled by the Steel Industry. The steel plant is a huge logistical hub, where iron is not the major stream in terms of mass. Water, carbon dioxide (CO2) and steam put together outweighs steel by almost a factor of 10 in the output streams of a typical integrated steel plant.

Effluent Conveyance System called as Effluent Channel Project (ECP) is provided to carry treated effluent from industries (mostly chemical) located near Vadodara to the Gulf of Cambey, Arabian Sea. The industries along the stretch in the area from Padra Taluka (Vadodara District) and Jambusar Taluka (Bharuch District) also join the ECP for effluent discharge.

L Pugazhenthy calls for encouraging more and more eco-friendly zinc recycling units to promote clean operations as lot of zinc wastes are being generated today.

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.
