Sustainable design for locating sorting centers of municipal solid waste

Abstract

Recycling of municipal solid waste (MSW) as a process for closing the supply chain of many products is mainly the value of this category of products after use cannot be improved. It cannot be denied that in the past decade process of recycling urban waste material in Iran has made enormous progress. However, compared to the other countries, there is a weak sense. In this study, a bi-objective integer programming model to minimize overall costs and maximize profits at sorting centers modeled. The aim is to optimize the costs and benefits and general interaction among us is dimensionally permanent In this study, all three dimensions of sustainability, including the technical, environmental and social considered in to the proposed model. To cope with bi-objectiveness of the problem, a multi-choice goal programming (MCGP) approach applied. Then, the model is solved by CPLEX solver to test its validity. Finally, the computational results show the applicability of the proposed methodology in the real world.
