An Integrated Waste Management Program for High Ash Papermill Sludge, 1990 Environmental Conference Proceedings

The nation’s solid waste crisis is being translated into aggressive regulatory programs of waste reduction and recycling. For example, the Wisconsin Department of Natural Resources (WDNR)has set a waste reduction goal of 75-90% for pulp and papermill sludge (representing 1.1 - 1.4 million tons of sludge per year) for Wisconsin pulp and papermills.

Pope & Talbot has developed an integrated waste management approach to waste reduction and recycling. The program coordinates four disposal options: 1) landspreading; 2) reduction of sludge to ash by combustion: 3) landfilling ash; and 4) landfilling sludge.

The integrated waste management program has been fully operational for two years. In 1989, 36% of the sludge was recycled by landspreading. 54% underwent combustion for process steam and 10% of the sludge was landfilled. The implementation of this integrated waste management program has reduced landfill demand by 78% and has stabilized the economies of sludge disposal.
