Beneficial Use of Residuals
Residual Types & Uses
As part of the manufacturing process, the forest products industry generates several types of solid residuals such as boiler ash, causticizing residuals, woody biomass, secondary fiber rejects, and wastewater treatment solids. Due to their chemical and physical properties, these residuals have many beneficial uses as substitutes for raw materials in other manufacturing, geotechnical, agricultural, and silvicultural applications. Reuse of these materials has the additional benefit of reducing disposal costs by extending the life of existing landfills. Work in this area primarily focuses on connecting Member Companies to the large volume of technical information NCASI has produced over the years to help with the implementation of successful beneficial use project.
