Sewage sludge is considered as a main product obtained from urban liquid effluents that are discharged into sanitation systems of wastewater treatment plants. The aim of this work was to reuse it as compost, after the dehydration process, to replace the amendment applied in agriculture and also to reduce the environmental pollution caused by solid wastes.

The organic matters and nutrients in sewage maure will fertilize the soil as good or maybe even better than chemical fertilizers, which are already known as dangerous and harmful to the environment.
