摘要

Cleaner production (CP) is the continuous application of a preventive environmental strategy applied to processes, products and services to increase efficiency and reduce the risks to humans and the environment. Such production processes conserve raw materials and energy, eliminate toxic raw materials, and reduce the quantity of toxicity of all emissions and wastes at the source. The primary aim is to reduce negative impacts along the entire life cycle of a product, from design to ultimate disposal. In Indian steel sector traditional approaches to environmental control are mostly used through the application of "end-of-pipe" technologies. However, with increasing cost of the traditional approaches, some of the progressive steel manufacturing companies are resorting to cleaner production processes. Some of the features of these processes are : 1. The system design focuses not on linear throughput of materials but on continuous reduction in energy, materials and wastes.2. Each system calls for an integrated approach to design, manufacture, and use of product.3. The use of each system results in a series of waste reduction measures. 4. Each system, over the long run, is cheaper and cleaner than conventional "end-of-pipe" clean-up technology. The use of a newly emerging smelting reduction (SR) process that is used for making hot metal (molten iron) in a steel plant has been used as an example to illustrate the critical issues involved in the application of clean technology in the Indian steel sector. The advantages and economic benefits of a SR based steel plant have been analysed. The paper also discusses important results of a Life Cycle Assessment (LCA) study carried out by the National Metallurgical Laboratory (NML), Jamshedpur for the integrated steel sector in India to identify and prioritise cleaner production and waste management opportunities. Typical examples of process reengineering carried out in Indian steel plants for reduction of pollutant emission as well as energy conservation are also summarised.
