  • Abstract:
  • Industrial Ecosystem is highly degenerative and during the production process, it generates a lot of by product and wastes, which includes both solid and gaseous substances. Industrial Ecosystem also contribute substantially to environmental pollution through contribution to Green House Gas emission. Management of Industrial by product and waste is a huge challenge. So effective Industrial by product and waste management is essential for sustainability of the Industrial Ecosystem. The developing countries are growing at a fast pace, due to which migration of population from hinterland to cities is taking place in an unprecedented rate. This is leading to growth of urbanization at a rapid pace. In order to cater to that, there is a need to augment the Infrastructure. So can the Industrial by products be used to build the Urban Infrastructure which will help in achieving a sustainable growth for both Industry and Urban Infrastructure ? In this article, we have examined the case of by product generation by firms in Indian Iron and Steel Industry (IISI) and their use in building urban Infrastructure. Production of Iron and Steel is a complex process and during the entire production cycle, iron ore is processed through a no. of intertwined and integrated steps to deliver the final output. Slag is one of the by product generated both during the production of Iron (Blast Furnace Slag) and Steel (LD Slag) in addition to other gaseous by products and flue dust. A lot of studies were conducted in different countries like USA, European countries , Japan and China about the use of LD slag for development of urban infrastructure like land filling and road construction. Off late studies were also conducted about the use of LD slag as a substitute for fertilizer. It has been observed that countries like USA, European countries , Japan, China etc. effectively utilize the LD slag and Blast Furnace slag for land filling, road construction, production of cement and use as a substitute for aggregate and sand. Even some of the countries are effectively utilizing the LD slag as a substitute for fertilizer. Use of LD slag not only helps in conserving the natural resources but also helps in reducing the carbon foot print thus creating a sustainable Ecosystem. But in the Indian context studies are scant about use of LD slag for land filling and road construction although few firms in Indian Iron and Steel Industry are working towards hundred percent solid waste utilization by utilizing the by products for Infrastructure development. To address this gap, we have collected data from secondary sources regarding use of LD slag for few firms in the Indian Iron and Steel Industry. India being a developing economy, needs to develop a lot of urban infrastructure to cater to the need of the future population that will migrate from the hinterland to the urban spaces. LD slag can be effectively utilized for building Urban Infrastructure especially land filling and road construction. LD slag contains lime, which makes it unstable and thus it becomes unsuitable for use in road construction. So weathering of LD slag is required to increase the stability which can subsequently be used in the subbase of the road. Use of LD slag for road construction can eliminate the use of a lot of natural resources like sand and aggregate which will lead to it’s conservation and thus creation of a sustainable ecosystem. From the literature, It has also been observed that LD slag use in Hot mix Asphalt (HMA) for road construction is being deployed on a trial basis in many countries especially in China. The result of use of LD slag in HMA is showing an encouraging result and also it’s use is reducing the Green House Gas emission. But in India the use of LD slag in HMA is scarce. Similarly use of LD slag as a substitute for fertilizer is being tried in other countries and the results are encouraging. But in the Indian context the use of LD slag as a substitute for fertilizer is also limited. So there is scope future research in all these areas for use of Industrial by product for creation of urban infrastructure. If found successful, then it will help in creating a sustainable ecosystem which will lead to regenerativeness.
