Biomass is the general name of all non-fossilized biological material obtained from living or recently living organisms. The structure of biomass consists mix of carbon, nitrogen, hydrogen, and oxygen. Global warming, pollution and the rapid depletion of non-renewable resources are the issues that need to be solved today. Biomass is a renewable energy source that generates heat, electricity and fuel using different conversion methods therefore biomass is an organic alternative to provide solutions to these problems. Thermochemical conversion technologies such as combustion, gasification, pyrolysis and biochemical conversion technologies such as anaerobic digestion, fermentation are used to procure energy from biomass. The study focuses on the location selection for biomass to energy plants to enhance a sustainable biomass supply chain. The location selection problem includes economic, environmental, social and technical decision factors. In this study, a decision support system has been developed by using Fuzzy Cognitive Mapping method (FCM) to establish the relationship between these decision factors. A preliminary study was conducted in which biomass supply chain experts are interviewed to reveal the relationship between decision factors. The findings obtained from expert opinions were solved in a MATLAB based FCM decision support algorithm. At the end of the study, scenario analysis is conducted in order to better understand the relationship between decision factors.
