Abstract :

One of the main causes of soil and air pollution is UrbanWaste. Also, this type of waste can produces methane that can increaseamount of greenhouse gases. One of the way to decreasing theseproblems is Using organic waste for production energy and compost.Method: In this research, Case Study research method used. Forgathering part of information, more than 100 questionnaires form hasbeen distributed. Also from the library information and the web site ofsome active company in the field of biogas production is used. Foreconomic assessment "Net Present Worth method" that is one of thereliable economic methods has been applied.Findings: In this paper has been focused to Technical and economicassessment for establishing a 600kw biogas power plant by using 73tone urban waste in Robat Karim region.This study is showed with 50billion Rial initial cost establishing a biogas power plant for produceelectricity, heat and compost is possible and during project priod willbe back all of initial and maintenance cost and in the end of age project,more than 30 billion Rials benefit can be obtained. Therefore, itsimplementation strongly recommendedConclusion: Although this research was done for ROBAT KARIMregion, but results show that establishing biogas power plant forproduction energy and compost in all regions with close ROBATKARIM characteristics, is economical. Therefore doing this kind ofprojects for urban waste management is recommended .
