Research on the Potential of Resource Saving and Emission Reducing of Papermaking Industry in China: Based on Environment Learning Curve

摘要

This paper uses sectional data to analyse the structure of papermaking industry and its environmental influence. In the other hand, this paper uses statistical data in 1992-2010, and takes the energy and water consumption, waste gas, SO_2, mist and dust, waste water, COD, the solid waste discharge per 10~4 RMB Yuan as indexes. The relation between these indexes and economical development is analyzed with the technical advancement and the environmental protection consciousness enhancement, and the statistical model of papermaking industry is established. According to these models, the potentials of saving resources and reducing pollution are calculated. The results are showed that: with economic development, each index is falling by power model, and the relevance presents is high. The environmental loads of different periods gradually drop, because the technical is progressing and the people's environmental protection consciousness is enhancing. The potentials of saving resources and reducing pollution are falling in papermaking industry, but the potential of present stage is high. This provides scientific foundation for the realization of paper-making industry clean production and environmental friendly economy.
