Abstract

Use of virgin and post-consumer corrugated board as a replacement for bentonite in slurry mixes was investigated. The effectiveness of the slurry mixes was assessed using typical tests including Marsh funnel viscosity, density, and filtrate loss. Filter cake permeability was also determined. Corrugated board was fiberized for the test program. Test results indicated that corrugated board could be used to replace 9 to 27% (0.5 to 1.5% corrugate content) of bentonite in slurry mixes with a total solids content of 5.5%. Slurry applications provide a new and viable beneficial reuse alternative for paper/paperboard products, which constitute the largest weight and volume fraction of municipal solid waste generated and disposed of in the U.S.
