Environmental performance analysis of clean production and end-pipe treatment
清洁生产和末端治理环境绩效对比分析

Based on statistics of industrial pollutant yields and discharge quantity in Jilin Province, the non-residual decomposition model was applied to quantify the net amount of environmental benefits of clean production and end-pipe treatment respectively. Environmental performances of end-of-pipe and pollution prevention strategies were further analyzed to explore an appropriate way of improving regional industrial ecological transition. The results showed that industrial symbiosis did not exert a positive effect on environment improvement. Technical factor promoted environmental performance improvement in clean production, while both technical factor and scale factor did in end-pipe treatment. Clean production was superior to end-pipe treatment in pollution volume reduction, which implied that prevention strategy dominated over end-of-pipe strategy, but the improvement of clean production tended to slow down. It is necessary to construct a proper industrial ecological system for the realization of environmental goals.
