Abstract—Waste to Energy (WtE) is becoming an interesting
option for many countries as an effective waste management
solution. The goal of this study is the selection of a suitable WtE
technology for the treatment of municipal solid waste in Greater
Beirut Area (GBA). In adopting a potential WtE technology for
solid waste treatment in GBA, the protection of the environment
and citizens health is mandatory, but it is also evident the
pressing need for economically feasible new electrical energy
sources. For a well and an efficient functioning of a WtE plant,
an appropriate supply chain system of municipal solid waste
should be guaranteed. The selection of a suitable WtE
technology is a complex decision and to achieve the stated
objective the Analytic Hierarchy Process (AHP) method was
employed and experts in the waste management sector were
consulted to formulate the model. AHP analysis was performed
using SpiceLogic software. Results indicate that Composting is
the best choice with a global score of 0.33, followed by Anaerobic
Digestion which acquired 0.21 and Incineration ranked as the
third preferred technology obtaining 0.14. A sensitivity analysis
was conducted to ensure the results consistency, assessing the
reliability of the experts’ judgments.
