Introduction: Current energy sources are coming to end and one of the main priorities of the country’s management is the energy recovery from renewable energy. Considerable quantity of municipal solid waste (MSW) is one of the most serious urban pollution sources. Impact assessment matrix is a new and fast tool for Environmental Impact Assessment (EIA).
Materials and Methods: In this regard, renewable energy like waste-to-energy was investigated. Environmental assessment method was performed to evaluate the environmental impacts of common Waste to Energy (WTE) technologies by Wooten and Rau matrix. Most available WTE technologies (anaerobic digestion, sanitary landfill with gas recovery, waste incineration, and gasification) were environmentally assessed and compared.
Results: Results showed that anaerobic digestion could be most environmental friendly WTE technology for production of renewable energy from organic waste and could be considered. Furthermore, executives as green minded managements can improve the quality of waste management by finding new solutions. Other technologies such as landfill by gas recovery and gasification will be ranked second and third in terms of environmental effect.
Conclusion: Results showed that performing anaerobic digestion technology will produce less environmental impact in long term. Then landfilling by gas recovery and gasification technologies will be ranked second and third in terms of environmental effect.
