a trend of significant increase in municipal solid waste generation has been recorded worldwide. this has been found due to over population growth rate, industrialization, urbanization and economic growth. consumerism speed has been found very high covering around more then 50% of total population since last decade due to higher economic growth, which has ultimately resulted in increased solid ...

background : due to the crucial role of dental solid waste in the spreading of pathogens and threats to human health and the environment, its optimal management is very important. methods: this was a descriptive cross-sectional study. the study population consisted of 40 dental centers, from among which 11 dental centers were selected through random sampling. from each center, 3 samples were co...

Collection of Municipal Solid Waste (MSW) accounts for a significant proportion of most municipal budgets, and has drawn some degree of researchers‟ interest. This study was conducted in Ota, Southwest Nigeria, to explore the use of Visual basic program as an innovative tool to select the most economic haulage system among three systems found in literature (conventional-, modified- and Stationa...

This paper describes the inadequacies of public provision for solid waste collection and disposal in Benin City (and also in other Nigerian cities) and the limitations of the privatized schemes that have sought to address these inadequacies. Its description of solid waste management in Benin City draws on the author’s interviews with 591 households which revealed that three-fifths had no solid ...

The aim of this paper is to present and compare alternative hierarchical formulations for the periodic vehicle routing problem applied to solid waste collection. The solution of this problem is a one-week plan of daily routes for the transportation of mixed solid waste from containers to disposal facilities, taking into consideration the frequency of collection of each container within the plan...

In the present paper the Ant Colony Optimization (ACO) Algorithm is introduced for best routing identification applied in urban solid waste collection. The proposed solid waste management system is based on a geo-referenced Spatial Database supported by a Geographic Information System (GIS). The GIS takes into account all the required parameters for solid waste collection. These parameters invo...

The collection of waste is a highly visible and important municipal service that involves large expenditures. Waste collection problems are, however, one of the most difficult operational problems to solve. This paper describes the optimization of vehicle routes and schedules for collecting municipal solid waste in Eastern Finland. The solutions are generated by a recently developed guided vari...
