Assessment of the Potential for Water Reuse in the Pulp and Paper Industry

摘要

This research study assesses the current extent of water reuse and recycle in the U.S. pulp and paper industry and identifies the potential for increasing overall water reuse and recycle. The study focuses on the 10 largest water consuming groups in the industry, found to utilize nearly 85% of the total water withdrawn by the entire industry. Using a systems analysis approach, major subprocess functions are identified and reviewed for technical limitations to further recycle and reuse. Regional, environmental, and economic constraints are also identified and projections made of the feasible water savings potential for the production groups studied. The study closes with an identification of areas where further research is needed to encourage water reuse and recycle.
