PENA-MONTOYA, Claudia Cecilia et al. SOLID WASTE MANAGEMENT IN CLOSED-LOOP SUPPLY CHAINS FROM THE PERSPECTIVE OF OPERATIONS RESEARCH. Luna Azul [online]. 2015, n.41, pp.5-28. ISSN 1909-2474.  https://doi.org/10.17151/luaz.2015.41.2.

The integration of reverse and direct flows within the supply chain is highly benefitial to reduce costs and avoid the enviromental damage because value from the solid waste is recovered; this integration is known as closed-loop supply chain. Most of the reported experiences regarding closed-loop supply chains and solid waste management decisions come from developed countries with strict environmental regulations and use of operations research techniques.This paper aims to identify the feasibility of applying operations research techniques to solid waste magement decisions within closed-loop supply chains in developing countries such as Colombia. Important variables such as the different kinds of solid waste, the regions and the use of optimization, simulation and multi-criteria techniques were identified by reviewing research articles. Technologic watch methodology was used to correlate these variables. The results showed that the multi-criteria technique is most frequently used because it allows including different aspects related to a single decision; therefore, the use of this technique would be appropiate to effectively approach the main decisions at the emerging closed-loop supply chains in developing countries.

Keywords : Supply chain; closed loop; multicriteria analysis; optimization; solid waste; simulation.
