Background and Purpose: History of implementing civil projects and plans in Iran indicates a lowered attention to environmental effects of civil projects in the past, leading to contamination of various environmental resources nationwide. In order to avoid such threats particularly in establishing composting plants, evaluation of environmental effects must be considered. Therefore, we decided to take a step forward for sustained development by evaluating the environmental effects before a composting plant is established in Sabzevar, Iran. Methods and Materials: In this descriptive study, three geographical zones were selected around Sabzevar for establishing the plant, and two of them were rejected and the third one (5 km from the city) was chosen for further evaluation. The positive and negative environmental effects were also considered. Results: The negative effects of establishing the plant for the time of operation were given 11 points and for the time of construction were 18 points; its positive effects were given 27 points for both construction and operation times. The algebraic sum of negative and positive points came up to be 16 positive and 9 negative points. Conclusion: The study results and the comparison of negative and positive effects of establishing the composting plant in the specified location in Sabzevar, Iran can be considered positive and its implementation is feasible.
