| Abstract | ||
| Agricultural waste represents a heavy burden on the environment, in addition to the deterioration of agricultural production. Therefore, the study aimed to provide a sustainable, low-cost, industrially and environmentally safe energy source, in addition to producing organic fertilizers with high fertilizer value and low costs. Therefore, the study relied on conducting an economic feasibility study for biogas units with capacities of 4 m3 and 6 m3 in some modern areas of the two governorates (Fayoum, Assiut) ), Where the total number of the sample items reached 100, and a sensitivity analysis was conducted to measure the tolerance of units and predict the amount of agricultural, plant and animal waste during the period (2019 - 2030), the most important results were that the biogas production unit with a capacity of 4 m3 meets 100% of The household needs from gas and provides 13 job opportunities for seasonal workers, which meet about 35% of the energy needs of the farms, and provide an income estimated at about 4760 pounds annually, as well as the biogas production unit with a capacity of 6 m3 that meets 100% of the household's needs of gas + equivalent 2 cylinders of a cooker per month that can be used in the animal barn or sold and provides 15 job opportunities for seasonal workers, which meet about 50% of the farmer's energy needs, provide an income estimated at about 7040 pounds annually. | ||
