SUGGESTING A COMPLETE MECHANICAL SYSTEM TO SORT HOUSEHOLD SOLID WASTES

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.
