Protection of Environment in an Integrated Steel Plant...

Protection of Environment in an Integrated Steel Plant  The processes of an integrated steel plant are highly resource intensive, consequently emitting and discharging pollutants and therefore, the cause of environmental concerns. They have a variety of impacts on the environment. The main impacts come from the use of energy and raw materials, which result in emissions such as carbon dioxide (CO2), sulphur oxides (SOx), nitrogen oxides (NOx), dust emissions to air. Water is used throughout the plant for cooling or heat transfer of heat processing equipment. Water is also required for descaling, dust scrubbing, quenching and other processes. Direct contact water gets contaminated during use and when this contaminated water is discharged from the plant, it impacts the environment. Also solid wastes generated during the plant operations, need dumping in the land filling area. These wastes also have its effects on the environment. One more factor which affects the environment is the noise which is produced during the plant operations. In short, thera are four types of pollutants which are affecting the environments (Fig 1). These are (i) air emissions, (ii) liquid effluent discharges, (iii) solid waste dumping, and (iv) generation of noise. Fig 1 Types of pollutants affecting environment The steel plant is required to be in compliance with regulations for meeting both generic standards for air, water, noise, waste management as well as specific standards for steel industry. The plant is required to meet the environmental norms for coke ovens, sinter plant, blast furnace, steel melting shop, rolling mills etc. for stack emissions, fugitive emissions and effluent discharges. It is also to comply with the ambient air quality standards. The steel plant is to take measures to improve its environmental performance not only for complying with the statutory environmental norms but also...

Creating Sustainable Future for Excellence...

Creating Sustainable Future for Excellence  An organization can achieve sustainable excellence if it embraces and respects the environment in the present and cares for the well being of the  generations to follow. The concept of creating sustainable future is broadly defined as meeting the needs of the present generation without compromising the ability of future generations to meet their needs. The ability to adapt to change is a crucial element for the survival and the key to success for an organization. The critical issue of the present time is the ability to sustain  in the face of rapid global change and resource competition. Everyone including employees and stakeholders are to play a part for creating a sustainable future. Management is to practice transformational stewardship and to find sustainable practices and strategies for the organization to create sustainable future. The principles adopted by the organization creating sustainable future are more holistic than the practices followed in the past. The management is to recognize that both the need for return on investment, the wise use of resources, and seeking the well being of their employees and stakeholders are equally important. The organization creating sustainable future is to utilize appropriate technologies and strategies for securing its future and to benefit its neighborhood. It is to shift towards the practices that respect people, profit and planet to remain not just competitive, but secure in the market. Organization creating sustainable future take managerial decisions which are based not only on financial concerns but also on environmental and social concerns. Such organization (i) creates long term financial value, (ii) knows how its actions affect the environment and actively work to reduce their impacts, (iii) cares about its employees, customers, communities, and other stakeholders and work towards making positive social changes,...
