Water footprint (WF) is widely used as a life cycle assessment (LCA) tool to assess the environmental impacts of water usage associated with forestry-based production. The calculations of WF are significantly influenced by the raw materials and the process. Some information is available on WF in the papermaking industry. However, there has been little consideration of the correlation between the WF and the properties of paper. Technically, the WF and the properties of paper are impacted by the raw materials. Generally, the ideal formula of raw materials used to make paper could decrease the WF while maintaining the properties of the paper. In the current study, the extreme vertices mixture design was used to optimize the WF and properties of the handsheet by the raw materials. The new model indicated that the WF of the handsheet was decreased significantly while the properties was maintained through the adjustment of the raw materials.

Papermaking industry is not only the water-intensive industry, but also the high wastewater discharge industry. The effective utilization of water resource has directly influence on the future development of papermaking industry. Accounting water footprint of papermaking industry can give many theoretic guidences to the solution of reasonable water resources allocation of the industry. In the paper, the concept of water footprint and its assessment system were introduced. The significance of water footprint assessment in papermaking industry and its bottlenecks faced with were also discussed.

In this paper, the reusing of waste water in the paper mill was studied, and the two important waste water treatment processes used in the mill were analyzed. Meanwhile, the internal recycling of the wastewater treated by sand filter in PM3 machine was introduced. Thanks to the application of the two treatment processes, fresh water consumption is absolutely reduced, and resulting the fall of the water footprint.

In this paper, the Na-based montmorillonite was added into the broke paper pulp, the content of the pitch in the broke paper pulp was efficiently decreased, the strength of the produced paper was improved, and the efficiency of the paper machine was also improved. At the same time, the consumption of clean water was dropped, therefore decreased the water footprint.
