Solid wastes is considered one of the top direct interactions between humans and the environment, hence the continuous growth of the population and their variety of social and economic activities lead to an enormous increase of the quantity and various forms of solid wastes. Physical, chemical, and biological characteristics are the most major parameters for classifying solid wastes. Moreover, it is classified according to their degree of danger as non-hazardous wastes, hazardous wastes, and extremely hazardous waste; unfortunately, the governorate of Beni Sueif contains some hazardous wastes, such as cement dust, and the byproducts of thermal treatment of medical wastes, such as ash. In 2020, the total amount of solid wastes in Beni Sueif Governorate was estimated at 1690271.68 metric tons, which categorized as 1) agricultural waste 55%, 2) household wastes 27%, 3) waste resulting from canal and drainage system 10%, 4) wastes from demolition and construction 4%, 5) sewage network wastes such as sludge 3.5%, 6) medical wastes 0.12, and 7) industrial activity wastes 0.01%.
Generally, the process cycle of solid wastes in Beni Sueif Governorate has 4 consecutive stages, which are the collection and transportation, storage, recycling, and the final disposal stage. Unfortunately, the efficiency of the management system of solid wastes is low due to either lack of infrastructure and resources or the cyclic process is not controlled. This research spotted several cities and small suburbs that do not have infrastructure that can manage solid wastes, for example Al-Fashn and Ihnasia, and therefore the efficiency of solid waste collection in these areas is decreased to 25–60% for the Al-Fashn town and 25–66% for the Ihnasia town.
The efficiency of the solid waste management system is primarily dependent on two factors: A) the tools of the solid waste management system, such as equipment and operators, and B) cost, as the estimated value of the difference between expenses and revenues is -5038074 EGP; that requires looking for ways to sustainably mange the solid wastes sector, such as increasing resources, reviewing usufruct contracts between the administrative authority represented in Beni Sueif Governorate and investors. This would achieve extra economic benefits, which contributes to increasing the density of tools and infrastructure in the study area.
The ecosystems in Beni Suef governorate are affected by the methods of solid wastes management, which include recycling, disposal in landfills, and composting. Each method has a unique effect on the ecosystems; for example, the incineration of medical solid wastes can increase emissions of greenhouse gases such as methane, carbon dioxide, and aerosols. While recycling can produce new materials with poor characteristics such household waste-derived fertilizer lacks physical and chemical evaluation and may causes transmission heavy metals to plant tissues. Landfilling can cause the contamination of ground and surface water with leachate. As a result of sentinel 5p satellite data (Copernicus mission) the area surrounding solid wastes in Beni Sueif Governorate observed with high emission of greenhouse gases such as methane, carbon dioxide, and aerosols, similarly according to the result of physical and chemical analysis of water samples near to the area have infrastructure to manage solid wastes observed an increase of concentrations of chemical elements such as , aluminum, vanadium, zinc, cobalt and copper in water resources, in addition to the distance between Nile river and eastern ghayada landfill was 3238 meters.
Beni Sueif Governorate lacks a system for managing hazardous solid wastes such as cement dust and ash from incineration of medical waste. So it is necessary to design a method to find areas suitable for disposal of these types of wastes. Socio-economic, environmental, and geologic parameters are essential parameters that depend on multi-criteria decision-making. Finally, this study effectively identified the optimum location for hazardous solid waste landfilling.
