The study aimed to identify the economic and environmental returns of cultivating jatropha on treated wastewater in the Sarabium forest, which is estimated at an area of about 8 thousand acres and located near the treatment plant in Ismailia Governorate, and to identify the possibility of expanding the reuse of treated wastewater in agriculture, as well as identifying the environmental impact. For the cultivation of tree forests using treated wastewater.


The feasibility was confirmed in accordance with the financial and economic criteria used, as the net present value (NPV) was estimated at about EGP 348,616, which means that the project achieves a return of 12% in addition to this amount, and the internal rate of return (IRR) is about 48%, which is higher than the available opportunity cost. For investment, estimated at 12%, which is the discount rate announced by the Central Bank of Egypt, meaning that it obtains interest on its investments and its costs are estimated at about 48% over the lifespan. The rate of return for costs (B/C) was estimated at about 6.35, which is a very encouraging percentage and greater than the correct one. The ability to face market fluctuations, especially on the cost side, was demonstrated by conducting a sensitivity analysis, and the study recommended the need to expand the cultivation of jatropha using treated wastewater because of its positive effects on the environment and increase the national income
