Technical Bulletin No. 0931: Beneficial Use of By-Product Solids from the Kraft Recovery Cycle
Causticizing residues—slaker grits, green liquor dregs, and excess lime mud—are among the significant by-product solids from kraft pulp mills. These materials have chemical and physical properties that can make them suitable for a number of beneficial uses. The predominant use, especially for lime mud, is as a liming agent on agricultural land.
