Municipal solid waste management is one of the challenging issues in mega cities due to various interrelated factors such as operational costs and environmental concerns. Cost as one of the most significant constraints of municipal solid waste management can be effectively economized by efficient planning approaches. Considering diverse waste types in an integrated municipal solid waste system, a mathematical model of the location-routing problem is formulated and solved in this study in order to minimize the total cost of transportation and facility establishment.

With the Advent of ASEAN municipal solid waste (MSW) is estimated to increase 2-4% per year benchmarking waste management practices becomes of interest for the partner countries. This study surveyed logistics professionals from various parts ofThailandto obtain their feedback regarding waste management practices in their specific geographic location in terms of collection, transportation and disposal of the household and commercial waste.Refuse is collected in containers of various shapes and sizes ranging from baskets to metal and plastic garbage tons and dumpsters. The garbage truck size and type varies throughout Thailand but is more or less consistent within a municipality, rear loading with a crew of four including driver appears to be the standard, with sorting of garbage taking place at the truck at time of collection.

Selective Collection

The opportunity cost concept refers to quantifying the opportunities lost upon choosing one investment option over a more economical alternative. The present study applies the concept to the process of choosing the best investment option for managing municipal solid waste. In a case study in Brazil, the options on the table are bulk collection and tipping versus reverse logistics with selective collection and sale of recovered components. The use of relative monetary values renders the results general and applicable in other scenarios. The bulk tipping option represents the reference cost of 100. The research postulates a linear relation between the opportunity cost of bulk tipping (y) and the efficiency of reverse logistics operations (x). Zero efficiency means bulk collection and tipping of all waste. Full efficiency means capture of all recyclable items, which in the case study amount to 80% of waste. Various intermediate points confirm the relationship that takes the form y=0.968x. The result shows that opportunity cost is dynamic in as much as changes of technologies and administrative procedures move it along that line. It also illustrates to municipal administrations the immediate economic effect of implementation and stepwise improvement of reverse logistics.
