This research aimed to suggest a complete mechanical system to sort household waste solid to maximize its utilization. The study carried out at four factories for recycling household solid wastes to compost at El-Dakahlia and Damietta Governorates during October 2010. The study was conducted through three stages i.e. sorting the household wastes manually, evaluating the sorting systems and suggesting a complete mechanical system for sorting household waste to minimize the refused amount of waste.  From the results it can be concluded that; the manual sorting is benefit to sort the household solid wastes as quality sorting system (Zero wastes) but opposite in quantity (0.167 Mg.h.labor^-1) that was found by using the mechanical system done in the factories (0.625 – 0.977 Mg.h.labor^-1). The results explained that the two systems evaluated not enough to sort the all amount of the household wasted produced daily. Also the study cleared the re-sorted of organic mater and the wastes (refused) decreased the wastes values to 27.57 % in Beshla factory. For this reason must be suggestion the complete mechanical system consists of the adding units to the present factory to improve the waste sort quality and quantity.
