Abstract
This paper analyzes more than 50 papers with a limited area in the field of solid waste management systems
and supply chain management, extending over mathematical models that include economic factors, as well as
environmental and/or waste flow allocation. The review finds that there are a number of limitations to the current
research in sustainable solid waste management systems. The narrow scope of environmental factors as constraints in
the current models means that there is a need to go further and include new environmental metrics. The effective
inclusion of environmental objectives in models with improved multi-objective approaches is a gap that needs to be
filled. Furthermore, there are significant gaps in sensitivity analysis of models limiting the general applicability of the
models. The paper concludes with promising new avenues of research that demand effective inclusion of sustainability
into solid waste management system models.
