“…Collection costs in low and middle-income countries represent, respectively, 80-90% and 50-80% of the total cost of MSW management for companies [3]. In Urmia (Iran), 60% of the expenses with MSW management are related to the collection and transportation, with an average cost of US$ 114-120 [14].…”

“…In São Paulo, there are five transshipment stations in different areas of the city with an estimated volume of 1,200 tons per day [13]. In [14], the existence of 3,500 transshipment stations in the USA in 1999 it is reported. Among the studies that address the transshipment station, we highlight [9], who proposed a manual for guidance on the deployment and operation of transfer stations.…”

In this paper we analyze the impact of a transshipment station on the urban solid waste management, considering the trade-off among (i) transportation and operational costs of the transshipment; (ii) operational costs of the trips considering the transshipment station; and (iii) costs for the collection trips from the districts directly to the landfill. The study was carried out in the city of Belo Horizonte (Brazil), which produces 1,730 tons of urban solid waste per day. We have evaluated three scenarios: (i) baseline scenario, in which part of the solid waste is consolidated on a transshipment station and the other part is destined directly to the landfill; (ii) transport direct to the landfill; and (iii) consolidation of all solid waste on the transshipment station. We have evaluated these scenarios considering the cost of collecting and transporting the solid waste. We then analyzed the correlation between cost and distances: distance and total transportation cost have a positive correlation, and distance has a negative correlation with the unitary transportation cost (R$/km), i.e., when the distance increases, the cost of transportation per kilometer decreases. Our results indicate that the transshipment station has economic advantages for consolidating and transporting solid waste to a landfill. However, direct transport to a landfill is more profitable if the transportation cost (R$/km) increases up to 9.28%. If the transportation cost increases more than 15%, the operation cost of a transshipment station can increase up to 62%. However, an efficient operation in the transshipment station is critical to ensure this level of profit. Finally, the location of the transshipment station is imperative, and baseline scenario presents a better network for the urban solid waste logistics management.

“…For SWM applications, wireless communication technologies are mainly used for data communication. (Boustani et al, 2011;Isoaho and Peltoniemi, 2004;Johansson, 2006;Mcleod et al, 2013;Purohit and Bothale, 2011), GPRS (Ali et al, 2012;Faccio et al, 2011;Friedlos, 2005;O'connor, 2007;Vicentini et al, 2009;Wilson and Vincent, 2008) and VHFR (Lee and Thomas, 2004) were adopted by several solid waste collection and monitoring systems. The short-range communications technologies such as Wi-Fi (Chowdhury and Chowdhury, 2007;Hong et al, 2014), ZigBee (Catania and Ventura, 2014;Longhi et al, 2012) and Bluetooth (Friedlos, 2005;O'connor, 2007) were used among data acquisition nodes and sink nodes.…”

“…Respecto a lo anterior, se muestra la aplicación de un sistema GPS para subsanar las deficiencias en la operación, producidas por la pérdida de tiempo en una unidad de transferencia en la Ciudad de Hamilton (Ontario, Canadá), debido a la afluencia simultánea de un gran número de camiones recolectores (Wilson y Vincent 2008). Para otras aplicaciones en ciudades donde se busca cambiar de rutas fijas planeadas en función de pronósticos o datos históricos a rutas dinámicas ajustando las capacidades y recursos a las condiciones de demanda real, se han ideado distintos métodos con apoyo de dispositivos electrónicos tipo de identificación de radio frecuencia (RFID, por sus siglas en inglés), paquete general de servicio de radio (GPRS, por sus siglas en inglés), GPS junto con herramientas de sistemas de información geográfica (SIG) y de procesamiento de imágenes (Hannan et al (2011).…”

Palabras clave: basura, logística urbana, transporte RESUMEN La gestión de residuos sólidos urbanos es una tarea compleja que tiene implicaciones sociales, económicas, tecnológicas y ambientales para la sociedad y para las administraciones locales. La fase de recolección domiciliaria llega a representar entre el 70 y el 85 % de los costos totales de la gestión de los residuos sólidos, por lo que es un aspecto crítico dentro de la prestación del servicio. El objetivo de este estudio es analizar el sistema de recolección domiciliaria en el municipio de Santiago de Querétaro, México, con base en datos de recorridos reales obtenidos con dispositivos de geoposicionamiento global. Mediante un trabajo conjunto con autoridades vinculadas, se instrumentaron los camiones recolectores de basura y se monitorearon 71 rutas en operación. Se emplearon los métodos propuestos por la Secretaría de Desarrollo Social de México para evaluar los principales parámetros operativos y determinar el nivel de eficiencia de las rutas actuales. Los resultados muestran las ventajas de utilizar un equipo tecnológico de bajo costo y la importancia de incorporar la tecnología para sustentar cambios en áreas de costo críticas para fines de planeación, operación y control de un sistema clave en la preservación del ambiente.Key words: waste, urban logistics, transport ABSTRACTThe management of solid waste is a complex task for public authorities due to its social, economic, technological and environmental implications. Waste collection represents between 70 and 85 % of the total costs of managing solid waste, so it is a critical aspect of the service. The aim of this study is to assess the waste collection system in the municipality of Santiago de Querétaro, Mexico, based on GPS data. A fleet of garbage trucks was monitored, covering 71 waste collection routes. We used a conceptual route of methods proposed by the Ministry of Social Development (Secretaría de Desarrollo Social) of Mexico to assess the main operating parameters, determining the level of efficiency of the existing collection routes. The results show the advantages of using low-cost technological equipment in the planning and controlling of the solid waste collection systems, that play a key role in the environmental protection.
