ADOPTION OF SOCIABLE GREEN ENGINEERING FOR SUSTAINABLE DEVELOPMENT
India is striding ahead to become a world leader in manufacturing of ferrous metals & alloys. Rapid globalization has driven up-gradation to its ultra-modern infra-structure. It has contributed to India’s sustainable industrial growth in auto, infra, mining, petrochemicals, and power sectors. Hence over the decade, its per capita consumption of ferrous products has vastly increased. Existing units of iron and steel manufacturing industries emit the greenhouse gases (GHG) with variable life span with multiple and Global Warming Potential (GWP). These are responsible for the global climate changes. Global Warming & negligence of integrated impact of enviro-scoio-human-economic factors while achieving technological progress has today become the greatest challenge to the human endeavor for its continued and dignified existence on this planet. Clean Development Mechanism (CDM), which is multistage knowledge process is one of the ways identified under the KYOTO Protocol, for developed countries to offset their carbon emissions, is fast becoming the preferred way.Moreover, KYOTO protocol based market driven generation, registration, valuation of carbon credit and its subsequent trading leads to penalize the polluting and reward the clean industries. Consequently, authors have attempted to create awareness among the ferrous metal manufacturing industries to minimize the hazardous impact of GHG by investing in modernization of various sections, machineries and process of the integrated plants by discussing a few case studies and methodologies adopted to translate controlling carbon emission into a profit churning venture. Implementing alternative, appropriate, innovative, resource conserving, safe & green technology will lead to sustainable development.
A new methodology for greenhouse gas reduction in industry through improved heat exchanging and/or integration of combined heat and power
This paper presents a method that identi®es economically optimal combinations of enhanced heat recovery, integration of combined heat and power (CHP), and fuel switching, in an existing industrial energy system at various emission levels. Novel types of composite curves based on pinch technology, representing the existing temperature levels for supplying heat and the possible ones that may be attained after retro®tting, are used as tools for estimating the opportunities for CHP and the trade-off between improved heat exchangin
Did the metamorphosis from Export Processing Zones to Special Economic Zones improve the efficiency of trade enclaves in India?
In this paper, the efficiency of seven conventional Special Economic Zones in India is analyzed, by adopting a stochastic production frontier technique, for the period between 1986–1987 and 2007–2008.Results indicate that although the efficiency scores of these enclaves have improved over the years, specifically with the introduction of the SEZ policy (2000–2001), it is far below the threshold level as identified in the literature. Besides, one can also observe a discrepancy emerging between better export earning zones and efficient zones. On the determinants side, policy intervention and large geographical area, accompanied by clustering of units, are found to have impacted the efficiency scores of these enclaves positively.
