| Abstract:Based on the method developed by Professor Steen, combining with life cycle assessment and life cycle cost analysis methodologies and applying GaBi software developed by Germany PE Company, referencing to the case studies carried out by professor Steen and GUY SKANTZE, the eco-efficiencies of the two papermaking wastewater treatment systems in a papermaking company in Suzhou were calculated and compared by a LCC/LCA ratio. The difference between the two systems was that ultrafiltration apparatus was installed in the new wastewater treatment system. The results showed that the eco-efficiencies of the two systems were 90.18% and 92.47% respectively, which indicated that the ultrafiltration apparatus could reduce environmental impact and decrease environmental load in the wastewater treatment process.The measuring method of eco-efficiency discussed in this paper was not only fit for estimating the environmental influence of different technologies, but also for different products and services and even for different businesses. |
