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
Trade, exchange rate, and agricultural pricing policies in Thailand
Thailand is still largely an agricultural country. In 1984, agricultural work was still the main source of earnings for more than 70 percent of the population. For much of the 25 year period covered by this report, government intervention in the prices of rice, maize, and natural rubber was extensive. For these products, intervention took the form of explicit export taxes and restrictive quotas. Sugar, on the other hand, was imported until 1960. For many years prior to that, government policy was to encourage growers and thus achieve self-sufficiency. One conclusion of this study is that the Thai sugar industry would have shrunk dramatically if the government had refrained from intervention. Intervention in the prices of rice and natural rubber had the effect of penalizing farm producers by reducing their output prices. There was, as a consequence a shift of resources towards Thailand's small industrial sector. In 1981, the Thai government lifted its quota restrictions, and liberalized its trade by eliminating its intervention in the maize, rice, sugar and natural rubber markets. Unfortunately for export growers, however, the gradual elimination of intervention was overshadowed by sharp declines in the world prices of Thailand's major agricultural exports.
