Abstract The effects of different volumetric ratios of bulking agents to pulp/paper-mill sludge on composting were studied. Rice husk and corncob were used as bulking agents. Volumetric ratios of bulking agents to pulp/paper-mill sludge were used as 10:100 and 25:100. To monitor the evolution of the composting systems, routine parameters such as temperature, moisture, pH, total N, NH4 +-N, NO3 --N, total C, and C/N ratio were analyzed. The results indicated that the agro-based materials significantly affected compost maturity parameters. Moreover, the quality of the product obtained in the composting process treated with the agro-based materials achieved satisfactory stabilization and sanitation for application to land.

The pulp and paper industry released different chemical pollutants that are directly discharged into the environment without proper treatment. This experiment was carried out to study the effect of pulp paper mill sludge amendments with garden soil (25%, 50%, 75%, and 100%), and garden soil was utilized as a control in a pot experiment. This study revealed the growth parameters of Triticum aestivum and Brassica campestris in germination percentage and germination index values decreased with rising in sludge concentration. Further, Soil amended with 25% paper mill sludge slightly reduced the growth in root length, shoot length, biomass, photosynthetic, and 50% sludge amended soil had variable effects on the root, shoot, and photosynthetic pigment of T. aestivumand B. campestris. However, the toxicity of effluent on tubifex-tubifex worms was also carried out at selected concentrations (25%, 50%, 75%, and 100%). Results of the study suggested that after 24 hours of exposure (>25% concentration), tubifex worms showed various changes such as morphological changes; hemoglobin content disappeared at the lethal concentrations of pulp paper mill effluent; cell bursting, and the back of the body became white with body disintegration at the lethal concentrations of pulp paper mill effluent. This article mainly focuses on the toxicity of the organic pollutants in terrestrial and aquatic life due to pulp paper mill effluent.

Abstract The water quality of the upper 110 kilometres of the St. Croix River is considered to be pristine. A major industrial discharge renders the lower 14 kilometres of the river a water quality limited segment. Prior to 1970 the Georgia-Pacific Pulp and Paper Mill at Woodland, Maine, discharged untreated effluent directly into the river causing dissolved oxygen concentrations to drop well below 5 mg/L, the objective chosen in the interest of restoring endemic fish populations. Since 1972, the Mill has installed primary and secondary treatment, regulated river discharge rate and effluent composition which has greatly improved the summer dissolved oxygen regime. By 1980, dissolved oxygen concentrations were generally above 5.0 mg/L and restocking the river with Atlantic Salmon (Salmo salar) was initiated.
