Abstract

Mechanical-biological waste treatment process commonly produce an organic rich fraction containing nutrients and organic matter which have the potential to improve physical, chemical and biological health of soil. Based on recommended BMT-based integrated MSW management system, life cycle assessment is employed to compare the environmental impact potential (EIP) of two BMT-based waste treatment strategies (BMT-incineration and BMT-landfill) with traditional landfill and incineration in Kahrizak, Iran. The results show that the landfill has  higher impact on climate change and acidification while using BMT in landfill has decreased the effect on the climate change and also ‘incineration scenario’ has highest impact on fossil fuel, climate change and respiratory inorganic. While using BMT –incineration has decreased the effects on climate change and fossil fuels. The results verify that BMT based on MSW management would be environmentally reasonable and helpful to develop integrated MSW management system in Kahrizak, Iran.

Key words: Life cycle assessment, based waste treatment strategies, waste.
