The disposal of sewage sludge affects the environment as the sludge may contain harmful components such as pathogenic organisms, organic compounds, heavy metals and excess phosphorus and nitrogen. Depending on the method of disposal, these effects can be immediate or time-delayed and non-linear. The

โฆ Synopsis
The application of sewage sludge to agricultural fields may result in the production of Mo-rich herbage, a cause of metabolic disorders in animals. An alternative to application of sludge to agricultural fields is sludge utilization in strip-mine reclamation. Oxidation of strip-mine spoil material causes accumulation of Mo-rich iron oxyhydroxide in stream beds and spoil piles. Strip-mine reclamation by sludge application may induce short-term increases in the concentration of Mo and other metals in waters discharged from the reclaimed area because of pH dependent ion-exchange reactions and dissolution of Mo-bearing iron oxyhydroxides.

Possible nutrient limitations in single (activated sewage sludge) and dual (sludge plus phenol) co-disposals with refuse were examined with the objective of maintaining the fermentation balance and thus minimizing detrimental effects on leachate quality and, subsequent, environmental impacts. Labora
