Emission control with route optimization in solid waste collection process: A case study

Abstract

Solid waste collection processes are usually carried out by using trucks with diesel engine. In solid waste collection process, the trucks emit to environment different emissions from its exhausts. For this reason, in solid waste collection process, it is necessary that route optimization should be performed in order to decrease the emissions. This study was performed in Trabzon City with 39 districts, a shortest path model was used in order to optimize solid waste collection/hauling processes to minimize emission. Unless it performs route optimization in solid waste collection/hauling process, emissions increase due to empty miles negativeness. A software was used as an optimization tool. The software provided Geographical Information System (GIS) elements such as numerical pathways, demographic distribution data, container distribution data and solid waste production data. In addition, thematic container layer was having 777 points for the entire city. By using the software, the optimized route was compared with the present route. If the optimized route in solid waste collection system is used, route distance and route time will be decreased by 24·6 % and 44·3 % as mean of nine routes, respectively. By performing the stationary container collection process and route optimization, it is determined that CO 2 , NOx, HC, CO, PM emissions will be reduced 831·4, 12·8, 1·2, 0·4, 0·7 g per route, respectively.

A case analysis of a sustainable food supply chain distribution system—A multi-objective approach

“…Several optimisation techniques have been applied in designing distribution systems. Optimisation techniques are used for reducing operational and overall costs in different distribution systems, for example, food and drink distribution (Watson-Gandy and Dohrn 1973), goods distribution (Perl andDaskin 1984, 1985), agricultural goods transport (Ljungberg et al 2007), forest harvesting (Rönnqvist et al 2007), waste collection (Apaydin and Gonullu 2008;Caballero et al 2007;Kulcar 1996), disposal of hazardous material (Alumur and Kara 2007), obnoxious facility location-routing (Cappanera et al 2004), small package shippers (Stenger et al 2012), shipping industry (Gunnarsson et al 2006), blood bank location (Or and Pierskalla 1979) and medical evacuation ( Chan et al 2001).…”

Solución del problema de ruteo capacitado considerando efectos ambientales mediante una técnica híbrida

“…Este valor es muy comparable con el que fijó la oficina australiana de efecto invernadero, en el que se afirma que aproximadamente 2.7 kg C02 son emitidos por litro de combustible diésel. En la literatura que se enfoca en el estudio del consumo de combustible asociado a los problemas de ruteo se encuentran diferentes propuestas tales como: Apaydin y Gönüllü usan valores fijos para calcular el consumo de combustible [10]. Kuo calcula el consumo de combustible con respecto a la carga y velocidad del vehículo [11].…”

“…Si se reduce el consumo de combustibles de la industria del petróleo esto tiene efecto directo sobre la reducción de los gases de efecto invernadero [2,9]. Por lo tanto incluir el consumo de combustible en los modelos de ruteamiento verde se constituye en un aspecto de gran importancia a tener en cuenta para representar la situación real en la solución de los mismos [10]. De acuerdo con el informe del Departamento de Energía de Estados Unidos (2008), la velocidad de desplazamiento, el peso de la carga así como la distancia de transporte, son los factores que afectan el consumo de combustible.…”

Vehicle routing in an urban area: environmental and technological determinants

“…The vehicle-routing problem with this load-based cost objective is called the Energy Minimizing VRP. Apaydin and Gonullu [10] deal with route optimization in solid waste collection in order to decrease harmful diesel emission. They propose using Geographical Information System (GIS) elements such as numerical pathways to problem identification -as it was assumed in this paper.…”
