9. 9.3x
Lacking exact data concerning the bus, the amount of materials used in the production of a municipal bus was estimated by comparison with the car.
The material use in the production of the bus was assumed to be proportional to the use in the car.
As the weight of the car was 1,071 kg, and that of the bus, i.e. 10,000 kg; the proportion is 10,000/1,071= 9.3.

10. 8x
The amount of electric energy use in the production was estimated to be 8 times higher for the bus as compared to the car

13. Material intensity for use
The analysis of material intensity of the use phase of the vehicles themselves requires information on:
• Fuel consumption
• Tires used
• Materials for maintenance (repair and service)
• Water for washing
The analysis of material intensity of the transport infrastructure
requires information on:
• Materials for building and maintaining the roads
• Materials for peripheral infrastructure (street lights and
parking lots)

14. Material intensity for use
In the case of Lodz municipal buses:
fuel consumption is 34.3 l per 100 km; at a density of kg/l we obtain the value of 28.5 kg fuel used per 100 km. A bus drives 80,000 km per year, using 22,775 kg fuel annually; in a 12-year life cycle this value reaches 273,302 kg.
Oil consumption constitutes 1% in relation to the fuel consumption, hence per 100 km it is l (oil density = kg/l) and kg, respectively. The annual oil consumption is kg per 80,000 km, and in the whole life cycle it is 2,957 kg.

15. Material intensity for use
In Poland, municipal buses are washed every day, except in winter, when the ambient temperature is below -3°C. Then they are washed every third day. This adds up to a total of 280 days a year on average. During 12 years the bus is therefore washed 3360 times.

16. Material intensity for use
As for the energy used for vehicle heating, the bus was heated
for 198 hours (50 h in November, 77 h in December, 22 h
in January and 49 h in February (data for the year 1998/99).
The fuel consumption standard for heating is 3.5 l/h. The total
amount of fuel used for heating is thus 693 l or 575 kg. For the
whole life cycle this amounts to 6,902 kg.

17. Material intensity for use
The amount of spare parts used during a major repair of the bus is 1,603 kg. Such a repair is made four times a year, so annually this makes 6,415 kg, and during the whole life cycle 76,979 kg.
Tires in a bus are changed every third year (6 tires, each weighing 58 kg). During the whole life cycle it makes 1,392 kg.

19. Waste Management During the Use Phase
The transport intensity of the waste produced during the use of the car or bus, the unit tkm, defined as t tons transported km kilometres is used

20. Waste Management During the Use Phase
Copper, brass, aluminium, lead and steel scrap coming from repairs and disassembly of road devices and equipment as well as the bus amounts to 1,328 kg.
The material is sold to companies located at a distance of 30 km. The transport of scrap metal this distance thus adds up to 39.8 tkm annually; 478 tkm during the whole life cycle of the bus.

21. Waste Management During the Use Phase
The 60 kg car batteries of the bus are changed every 3 years. The batteries are then disposed of at the Mining and Steel Works “Orzel Bialy” in Bytom at a distance of about 190 km. Since 4 sets of batteries are used during the life cycle of the bus this adds up to annually 60x190/4=2.9 tkm, and for the whole life cycle tkm.

22. Waste Management During the Use Phase
On the whole, every year waste is transported at a distance of 422 km, so it is easy to calculate the quantity of fuel used in the entire life cycle as 1443 kg.
