Palestine is part of the world that faces problems in the disposal of waste, in addition to the restrictions imposed on the establishment of new landfills, so we have to think of other solutions to get rid of waste, such as waste separation and composting. Where the waste is separated either in the homes and this requires a high culture of the community, or sorting at the transfer stations. Where glass and metals are separated by one unit, plastic materials by unit and organic materials by unit. Palestine is an agricultural country; it is better to build a composting plant. Composting food and other organic waste provides a range of environmental benefits, including improving soil health and reducing greenhouse gas emissions. As the population grows, SW generation is increasing until it has now become a global problem. With the exacerbation of this problem, interest in SWM has increased. SWM is a process that includes collection, transporting, treatment and disposal of solid waste together with monitoring and regulation. Through the principle of SWM, the current situation will be evaluated, the main problem identified, and solutions will be found. SW is managed with the 3Rs concept: Reduce, Recycle and Reuse. And by focusing on this concept, waste minimization can be achieved in an efficient way. The principle of the 3Rs contributes to reduce the produced waste, saving money, and increasing responsibility in the matter of waste production. The produced waste can be treated by many ways, starting by sorting the waste in order of its type and this can be done in home or the transfer station or the final destination which is the landfill. after finishing the sorting part, it can be then separated from the other non-recyclable waste and this can be done manual and mechanical. and the final step will be by selling the sorted items to the factories that are interested in the recyclable wastes. And by that the environment will be protected from the danger of the solid waste in addition to achieving economic profits. After studying the project and analyzing the economic data, the results were positive and economically feasible, as the net profit was 7,415,986.8 Nis/Year with an initial investment of one million dollars (3,500,000 Nis) , the payback period was half a year, and the internal rate of return was 147% . These results were sufficient to determine the project's success and economic feasibility.
