Objectives Recycling is one of the methods to improve the management of solid waste, which has considerable economic and environmental benefits. Without knowing the amount of the waste and its components, the possibility of planning and optimizing the waste management system is impossible. The current study aimed at investigating the recycling potential of solid wastes in 13 municipal districts of Mashhad, Iran, quantitatively and qualitatively.Methods The current study was conducted in 2013 in 13 municipal districts of Mashhad. To conduct the study, it was necessary to know the physical analysis of municipal waste solid; therefore, the latest data of Waste Management Organization of Mashhad were used. Results The solid ingredients of the studied waste were paper and cardboard (46.7%), bread (10.8%), plastics (9.7%), metals (6.8%), and glasses (5%), respectively. There was a significant difference between the mean of the studied solid waste in winter and summer months. The total proceeds from the recycled materials was about US$ 369 836.45. The proceeds from the recycled metals was even more than that of other dry waste.Conclusion The recycled dry solid waste compromised 26.15% of the total dry solid waste. It is suggested to establish a waste separation system and also systematize the existing recycling industries in Mashhad according to the regulations to reduce the amount of solid waste, mange the costs and benefits result from Mashhad solid waste, and create new job opportunities and sources of income.

Introduction: One of the ways of optimizing the management of solid waste, is recycling which has considerable economic and environmental benefits. Whitout knowing the amount of the waste and its components, the possibility of accurate planning and optimization of the waste management system does not exist. The aim of this study was to evaluate a quantitative and qualitative and recycling potential of solid wastes in 13 regions of Mashhad. Methods: This study was conducted during the 12 mounths of 2012 in 13 regions of Mashhad municipality. This research was needed to know the phisical analysis of waste, so the information and statistical analysis of Waste Management Organization of Mashhad was used. Results: The solid parts of studied waste were paper and cardboard (46.7%), bread (10.8%), plastic (9.7%), metals (6.8%), glass (5%) and others (20%). There was a significant relationship between the amount of solid wastes in winter and summer months. The total income from selling of recycled materials was 14,793,458,000 rials. The income from selling of recycled paper is higher than other dry wastes. Conclusions: The amount of recycled dry solid waste was26.15%. It is recommended that by performing comprehensive studies and appropriate managemnt can effectively increase the percentage ofrecycling dry waste as well as proper recycling will lead to revenue and creating jobs in this sector.

Background &Objective: According to the existing documents a major portion of municipal solid wastes in Iran is being land filled and small portion of this material is recycled, while the municipal waste management in developing countries has moved towards source separation and recycling .This research was conducted by the purpose of estimating Qom municipal solid waste recycling potential and cost benefit,s in a 20-year vision since 2006.
Materials & Methods: This Research is a cross-sectional study. Firstly, according to the reports given by waste management organization in Qom city, dry solid waste recycling in 2006 and 2011 was estimated. Then two scenarios consisted of 20 and 60 percents of recycling were estimated to process the solid waste in 2011 and 2028 for enhancing recycling level ,and then cost benefit of them was determined.
Results: The average of produced solid waste was 718 ton per day in Qom city in 2011. Due to this producing process in 1407 we will have 1145 ton solid waste per day in this city. Daily economic benefit of dry solid waste recycling in 2011 was 15801520 Rials. If the recycling programs promotes, this benefit can be increased to 63211640 and 189664400 Rials for 20 to 60%recycling level.
Conclusion: Despite of 21 % potential for dry solid waste recycling in Qom city, nowadays about 5% of this substances are recycling. By upgrading the plan for 10 to 20 years, amount of economic benefit can be increased to 4 to 12 times.
