Sustainability Investigation in the Building Cement Production System Based on the LCA-Emergy Method
As one of the highest energy and resource consumption industries in China, discussion on the sustainability of the cement production system has great significance. This study conducted sustainable calculations and analyses for cement production systems based on the emergy method. This study also considers the sustainability impact of clean energy on the overall cement production system. Through a series of sustainable indicator measurements, the results prove that: (1) the two primary sections, non-renewable resource and non-renewable energy, contribute 88.6% and 11.1% of the emergy proportion, respectively; (2) the emergy sustainability indicator (ESI) was only 0.058, which is significantly less than the standard; (3) through the analysis of eight hypotheses, a very small change between the absolute values was found, which demonstrates that the sensitivity changes are within acceptable limits for the cement production system; and (4) by integrating the biological power generation subsystem, sustainability has been optimized in the cement production system. Finally, two ameliorated strategies are discussed in this paper for the better sustainability performance of the cement production system in the future.
