Since foundry industry is one of the major source of energy consumption and pollution emission (especially CO 2 ), issues concerning energy-saving and emission-reduction have been raised by governments and the industry. Specialists from around the world carried out multidimensional analyses and evaluation on the potentials in energy conservation and emissions reduction in iron and steel industry, and proposed various kinds of analyzing models. The primary measures mainly focus on the targeted policies formulation and also on clean and highefficient technologies development. The differences and similarities in energy conservation and emission reduction in foundry industry between China and other countries were discussed, while, the future development trend was also pointed out.展开更多
Based on a Life Cycle Assessment model, the effect of the whole life cycle of excessive commodity packaging on the environment was analyzed by eBalance Evaluation LCA software from production through circulation. The ...Based on a Life Cycle Assessment model, the effect of the whole life cycle of excessive commodity packaging on the environment was analyzed by eBalance Evaluation LCA software from production through circulation. The cost evaluation system and environment impact model of its three main processes, that is, material production, product machining and waste manufacturing, were established to identify the main environmental impact corresponding indicators and the influence on energy conservation and emissions reduction of excessive packaging life cycle. And packaging of moon-cakes was taken as an example to analyze the difference between the ordinary packaging and excessive packaging of moon-cakes in terms of life cycle assessment and costs analysis. Meanwhile some measures are put forward to conserve energy and reduce emissions.展开更多
