Summary

The purpose of this thesis is the estimation of diesel consumption of the garbage trucks and their emissions, during collection and transport of waste for one of the largest municipalities of Attica, the Municipality of Peristeri. Initially, the data were obtained from the Municipality of Peristeri about the diesel consumption of garbage trucks and the collection and transport routes. The data were collected on-site followed by field trip in the waste transfer station, the landfill, the mechanical sorting center of recyclables and the composting facility for biowaste treatment. The Municipality was divided in four different zones (urban, commercial, hill, business) to compare the fuel consumption of the garbage trucks. Consequently, the fuel consumption efficiency was estimated for each route of a garbage truck (liters (L) of fuel per mass (t) of waste). Furthermore, the fuel consumption efficiency was estimated for the three main waste categories (commingled, recyclable, bio-waste) and the four main garbage truck engines (EURO II, EURO IV, EURO V, EURO VI). Last, the air emissions of each garbage truck were studied for the pollutants: carbon dioxide (CO2), nitrogen oxides (NOX), hydrocarbons (HC) and particulate matter (PM) in comparison with the three waste categories and the four garbage truck engines. Important results were emerged regarding the effect of the zones of the Municipality of Peristeri on fuel consumption and on the environmental impact of the separate collection of bio-waste. It is concluded the effectiveness and impact of waste collection and transport for each zone, EURO engine and type of waste, while it is proposed various methods for reducing garbage truck fuel consumption and air emissions.
