Solid waste management is one of the existing challenges in urban areas and it is becoming a critical issue due to rapid increase in population. Appropriate solid waste management systems are important for improving the environment and the well-being of residents. In this paper, an Internet of Things(IoT) architecture for real time waste monitoring and collection has been proposed; able to impr...

The recent proliferation of facility-siting conflicts underscores the need for new analytical techniques in which the external effects associated with noxious facilities are considered explicitly. In general, in prescriptive facility-location models it is assumed that having populations "closer", as characterized by transport or accessibility advantages, is better for desirable facilities, but,...

Capacitated p-median problem (CPMP) is a well-known facility-location problem, in which p capacitated facility points are selected to satisfy n demand points in such a way that the total assigned demand to each facility does not exceed its capacity. Minimizing the total sum of distances between each demand point and its nearest facility point is the objective of the problem. Developing an effic...

BACKGROUND Refuse collectors are at a high risk for fatal and non-fatal occupational accidents. This is more intensified in developing countries, like Ethiopia, due to physically demanding nature of the job. However, information on occupational injuries and related factors are almost non-existent in Ethiopia. Thus, the aim of this study was to assess the prevalence of occupational injuries and ...

Landfill disposal and waste-to-energy (WTE) incineration remain the two principal options for managing municipal solid waste (MSW). One critical determinant of the acceptability of these options is the different health risks associated with each. In this analysis relying on published data and exposure modeling, we have performed health risk assessments for landfill disposal versus WTE treatment...

Municipal waste management has become a challenging issue with the rise in urban populations and changes people’s habits, particularly developing countries. Moreover, government policy plays an important role associated municipal management. Thus, this research proposes regional location routing problem (RLRP) model multi-depot (MRLRP) model, which are extensions of (LRP), to provide better col...

In this paper a new decision procedure for urban solid waste collection problem is introduced. The problem objective is to minimize the overall cost, which is essentially based on the time spent by the vehicles in the network. In the last years such a problem has been considered by several authors in the framework of the more general problem of planning a waste management system at a municipal ...

This paper provides an overview of the trend of generation, composition, and management of municipal solid waste, and estimates the carbon emissions arising from municipal solid waste management in Beijing. The correlation analysis conducted shows that the generation of municipal solid waste in Beijing has been growing steadily, showing high correlations (r > 0.9) to the total GDP, per capita i...
