Multicritery analysis for prioritizing the energy use of urban solid waste as a fuel in Paulista-PE

Paper aims: To carry out a multi-criteria analysis to assist decision making regarding the indication of the best alternative for converting solid waste energy into fuel. Originality: The innovative and advantageous approach analyzes the feasibility of deploying the technology, mainly due to new and significant information on waste energy recovery. Research method: The application of the system based on multi-criteria analysis, through the method of hierarchical analysis, according to previously established criteria, enables decision-making based on multiple criteria. Main findings: The criteria generated by the mathematical process presented the priorities of heat treatment technologies and energy potential according to the levels of preference and order of importance. Implications for theory and practice: The production refused derived fuel replaces petroleum-derived fuel sources, and reduces the amount of waste disposed of in landfills.
