Modelling of waste collection - a general approach to calculate fuel consumption and time

Abstract

A model for calculating time and energy consumption during the collection of waste with compacting trucks is presented. The model uses common statistics from a number of households in three different categories of residential area: the average distance from the residential area to treatment facility/transfer station, fuel consumption per km for the truck and average load and speed. This common and easily accessible information is completed with figures for time and energy consumption related to the extra work that is performed on account of stopping and emptying bins. Default values for those parameters are presented in this paper, estimated using data from a Swedish municipality. Data from four areas in Sweden were used for verification. The model predicts the real outcome relatively well: between 5 and 14% deviation for energy consumption and between 10 and 24% deviation for time consumption.
