Waste treatment technologies : approach to GHG emission and cost

Municipal solid waste may have a negative impact on the environment, causing pollution and greenhouse gas emissions (GHG) that contribute to climate change, if it is not treated. Treatment of waste is a key for sustainable development. Composting, anaerobic digestion and incineration are proven technologies for treatment of municipal solid waste. Selection of waste treatment depend on many factors, mainly cost, local conditions. Aim of this paper is to analyze different scenarios for waste treatment and their impact on environment and their cost.
