摘要
Cement production has drawn great attention on account of its high consumption and emission during its production process, which impeded system sustainable development. It has been a hot issue to assess the potential effect of environmental emissions and optimizes the production process. In this paper, emergy analysis is conducted to quantify the quality and hierarchy of the resources, products and services and calculate the eco-environmental supports and socioeconomic investments for integrated ecological economic assessment from perspective of ecological economic system. Meanwhile, regarding production process, socio-economic system and ecological economic system, carbide slag substitution scenario, maize straw fuel substitution scenario, and waste heat recovery scenario are respectively set up to account the resource conversion and recycling utilization efficiencies with comparison to baseline, thus quantifying the energy conservation and emission mitigation effects for cement industry. Finally, oriented to the emergy-based sustainability indicator, the ternary emergetic diagram will be conducted to identify the optimization allocation mode of various ecological elements during the cement production process and overcome the difficulty of process optimization for traditional emergy analysis in the future work.
