Pulping industry is generating appreciable quantities of solid wastes every day, the scientific ways and means of utilizing these solid wastes in an integrated eco-friendly manner was the main objective of this study. It was found that among the solid wastes of pulp industry, bio-sludge (BS) had wider C/N ratio. Hence it could be biodegraded for utilizing it as bio-manure. Lime sludge (LS) and primary clarifier sludge (PCS) were alkaline in nature with narrow C/N ratios and both the sludges had appreciable quantities of Ca and Mg. Hence these sludges have ameliorative potential for reclaiming acid soils too
