Abstract:Cement production consumes a considerable quantity of resources and energy and emits massive pollutants, which restricts the sustainable development of the cement industry. Therefore, a systematic method is needed to diagnose the sustainable development level of the cement production system and provide decision support for managers to implement the technology of energy-saving, consumptionreducing and pollution mitigation in the cement industry. This study revises the traditional emergy indicators, establishes a set of indicators system for cement production sustainability evaluation, compares and analyses the systems with and without waste heat power generation technology based on emergy synthesis. The study indicates that, the application of the waste heat power generation technology reduces the emergy flow with negative environmental consequences such as the electricity consumption emergy flow, and increases the sustainable development level of cement production system. The cement enterprises should change the emergy flow structure by the means of increasing the adoption rate of waste heat power generation technology and the proportion of industrial solid wastes in raw materials, adding more efficient desulfurization and denitrification treatment facilities, and adopting energy-saving equipment to improve the sustainable development level of cement industry.
