The study aimed at studying and measuring the impact of the economic and environmental of the production of biogas from sewage sludge on sustainable development in Egypt. It also aims to study the application of the Holding Company for water and wastewater and its subsidiaries in Egypt to study the production of biogas from sewage sludge, And the views of a sample of the employees of these companies, and the problem of research on the extent of the impact of the production of biogas from sewage sludge in terms of economic and environmental dimensions of sustainable development, and the researchers in this study to combine the method of extrapolation and the method of extraction The researchers used a survey list prepared for the purpose of collecting data according to the study variables, which consisted of the production of biogas from sewage sludge (independent variable) and sustainable development (a dependent variable). The researchers also used Alpha ). In addition, both simple and multiple regression analyzes were used to analyze the field study data using a sample of 376 individuals. The researchers found several results that showed a statistically significant effect between all dimensions of biogas production The researchers also highlighted the importance of adopting biogas production from sludge sludge to support the sustainable development of the Holding Company for Drinking Water and Sanitation and its subsidiaries. The researchers recommended a number of recommendations, including: Environmental policy includes a commitment to the formulation of environmental legislation and regulations, Which supports sustainable development and the development of an effective corporate environmental and economic management program for the production of biogas from sewage sludge to support sustainable development.
