The fuel consumption of vehicles used in the municipal waste collection was analyzed. A simple, but useful method was developed to estimate the fuel consumption of the vehicles for the transporting and collecting work phases. The results show the consumption norms of the typical collecting vehicles, working in a rural environment. It can be seen that the three-axis cars consume 20% more fuel while transporting and 30% more fuel while collecting waste. The efficiency of their utilization is much better, because they are able to collect 97% more waste, than the two axis ones. For rural service the average time requirement to reach the service area is around 30% of the workday, so the use of three-axis vehicles makes a significant saving. The saving in fuel means not only financial benefit but plays a very important role in decreasing the emission of CO2.
