Description: This report summarizes the results of a literature review on the utilization of paper industry sludges in commercial applications. The report begins with a discussion of the significance of paper industry sludge management as a regulatory and environmental issue. It also reviews paper production and effluent treatment processes, focusing on Ontario operations, as well as pulp and paper manufacturing processes and the types of sludges they generate. The paper includes comparative data on sludge composition at Ontario mills. It then reviews alternatives to the conventional disposal of paper industry sludges, including recycling, fiber and filler reclamation, and utilization in manufactured products. Finally, the report matches sludge properties and types to prospective uses, and defines market issues or constraints based on economics, manufacturing requirements, plant capacity, and plant location.
