It is also an important theme for adapting and responding to global environmental change. Aiming at a thorough examination of the implementation of ITGP in China, this paper presents its objectives, its three major areas, and their progress so far. It also identifies the key elements of its management and proposes new perspectives on managing green transformation. For instance, we introduce a case study on cement industry that shows the positive policy effects of reducing backward production capacity on PCDD/Fs emissions. Finally,to develop different transformation scenarios for a green future, we propose four strategies: 1) policy integration for promoting green industry, 2)system innovation and a multidisciplinary approach, 3) collaborative governance with all potential stakeholders, and 4) managing uncertainty,risks, and long-time horizons.展开更多

All processes of rice growth were finished in factory and they provided proper growth conditions (including light, CO2 concentration, temperature, moisture and minerals) on the base of different growth stages. This paper illustrated the theory of rice growth in factory, the processes of rice cultivation and fundamental structure of rice factory. It combined natural conditions with artificial environment to create an ideal rice growing environment. Rice cultivation’s cycle in factory was shortened and normally one day was divided into 2 - 3 special days. It could be continuous production and prevented rice planting from being affected by external conditions. Industrialized rice makes full use of energy on the basis of sunray and artificial supplies to increase the rice yield and it will start a revolution of rice planting and solve the problem of food safety.展开更多

The main parameters characterizing the quality for super-pure water, tap water and water from the intake in Besko (Poland) before and after the process in the plasma reactor were presented for comparison. In addition, the <sup>17</sup>O NMR (the full width at half maximum) and electrospray ionization mass spectrometry (ESI MS) methods were used to determine differences in physicochemical parameters between the untreated and plasma-treated water. It has been established that the water subjected to plasma treatment shows much different gas absorption properties than the untreated water samples, as a function of temperature and pressure, in this paper we report exemplary data for CO<sub>2</sub>, oxygen and acetylene. The improved gas absorption properties of the plasma-treated water make it attractive for the use in industrial processes. It is worth pointing to a great capacity of the new reactor (4000 l/h), and low energy consumption (20 MJ/h) for the treatment of the above mentioned volume flow rate of water.展开更多

Catalyst production, which was named ROC, has been successfully scaled up from laboratory formulations to commercial scale manufacture and over 100 tons of catalyst had been produced. The superiority in catalytic activity was identified by the evaluation tests of the ROC catalyst based on whatever kind of feedstocks (with their bromine index ranging from 400 mgBr/100g to 1 200 mgBr/100g) being used as the feedstock. The X-ray diffraction patterns had verified that the additive was highly dispersed on the surface of catalyst; the GC-FID analysis results showed that the ROC catalyst could increase the xylene content; the pyridine-FTIR spectroscopic analyses suggested that the additive could increase the amount of the weak L acids, which was the main cause leading to enhancement of the catalyst activity.展开更多

It found that (1) at its current stage, China's rapid industrial growth is accompanied by a slow increase in pollution; (2) environmental total factor productivity has become a primary driver of rapid growth with less pollution; (3) environmental control didn't cause any substantial restraint on China's industrial growth; (4) improvement in industrial environmental structure contributes an increasingly large share to economic growth with less pollution. China's industrial productivity is increasing, its growth model is being transformed, and the environment is exerting a diminishing constraint on economic growth.展开更多

Many environmental problems are facing industrial areas, especially in developing countries, due to poor industrial hazardous waste management. In order to reduce the effect of industrial waste on the environment and to reach sustainable development, countries have developed and reinforced several environmental protection laws and regulations. Yet, the waste disposals via incineration and/or landfilling according to cradle-to-grave concept require high capital, high running costs and are seen by industries as a barrier for further industrial development. Most importantly, disposals of waste deplete natural resources causing them to be unsustainable. Hence, various concepts and strategies have been suggested to promote industrial sustainability. The aim of this paper is to present different concepts and practices including Cradle-to-Cradle approach, Cleaner Production, Industrial Ecology, Eco-Industrial Park and Environmentally Balanced Industrial Complex described in literature that help develop a successful sustainable industrial community and reach zero pollution. These concepts are illustrated via case studies. Moreover, this paper tackles the challenges facing industrial areas in Egypt and emphasis on the imperative need for considering sustainable industrial community.展开更多

Though the majority of the apparel firms are engaging in processing, more and more firms are involved in marketing and branding. The upgrading trajectory of China apparel industry leads to the economic and social performances.
文摘To improve the comparability of the research results of ecological industry, the ecological footprint is appliedto analyze the resource utilization and environmental pollution in various subsystems, taking maize-MSG as a case.Results show that the production process from maize to MSG is a extended process of ecological footprint, and that theecological footprint of the maize production is the biggest; the extension of ecological footprint is followed by the increaseof footprint profit, which means that the extension of production chain is an important method to improve the resourcesprofit; the systems have a big proportion of the indirect energy ecological footprint; the air and water pollution in MSGsubsystem is the most serious. At last, it can be identified that ecological footprint is a good method to measure resourceutilization and environmental pollution in various subsystems of an integrated ecological industry.

文摘Using input, output and pollution data of industrial enterprises in 30 Chinese provinces and municipalities from 1998 to 2005, this paper creates an environmental production frontier function model to assess China's industrial growth sources, particularly environmental control and changes in the industrial environmental structure's impact on industrial productivity. It found that (1) at its current stage, China's rapid industrial growth is accompanied by a slow increase in pollution; (2) environmental total factor productivity has become a primary driver of rapid growth with less pollution; (3) environmental control didn't cause any substantial restraint on China's industrial growth; (4) improvement in industrial environmental structure contributes an increasingly large share to economic growth with less pollution. China's industrial productivity is increasing, its growth model is being transformed, and the environment is exerting a diminishing constraint on economic growth.
文摘Heat losses from the furnaces depend on the design and size. The surface heat loss from the bottom of an industrial AC electric arc furnace (EAF) possesses an important fraction of overall losses. So in this study the transient temperature variation at the bottom of the EAF was investigated. The transient temperature analysis was carried out using MATLAB computer program. T=T(r, t) for different bottom lining layers was depicted.
文摘Nowadays, the style of living that significantly depends on consumption of resources and over consumption patterns, tremendous increase in population, urbanization and industrialization resulted into generation of huge amounts of industrial wastes. Many environmental problems are facing industrial areas, especially in developing countries, due to poor industrial hazardous waste management. In order to reduce the effect of industrial waste on the environment and to reach sustainable development, countries have developed and reinforced several environmental protection laws and regulations. Yet, the waste disposals via incineration and/or landfilling according to cradle-to-grave concept require high capital, high running costs and are seen by industries as a barrier for further industrial development. Most importantly, disposals of waste deplete natural resources causing them to be unsustainable. Hence, various concepts and strategies have been suggested to promote industrial sustainability. The aim of this paper is to present different concepts and practices including Cradle-to-Cradle approach, Cleaner Production, Industrial Ecology, Eco-Industrial Park and Environmentally Balanced Industrial Complex described in literature that help develop a successful sustainable industrial community and reach zero pollution. These concepts are illustrated via case studies. Moreover, this paper tackles the challenges facing industrial areas in Egypt and emphasis on the imperative need for considering sustainable industrial community.
文摘China's price fluctuations increasingly exhibit significant structural characteristics,and since 2003,there have been several rounds of significant structural price rise.The degree of structural rise in the prices of industrial and agricultural products in China is not only higher than in the general developed countries and developing countries,but also more prominent than in other transition economies.And the structural rise in the prices of Chinese industrial and agricultural products exhibits significant economic zone differences:the structural fluctuations are the greatest in the central and western regions,significantly higher than in the eastern regions as well as the national average.From the perspective of causes of structural rise in the prices of Chinese industrial and agricultural products,the government must aim to coordinate the industrial and agricultural investments and bridge the gap in the industrial and agricultural technologies and supply capacity.
