In order to minimise CO2 emissions and the use of natural resources, Stuttgart’s main sewage treatment plant already generates electricity from methane gas, sludge incineration and solar power installations. This case focuses on the next step the Municipality has taken by tendering for a fleet made up entirely of electric vehicles. It has taken advantage of the fact that these vehicles are required to bear weight rather than travel at speed, in order to benefit from the environmental advantages of fully electric trucks. The technical specifications for these alternative fuel vehicles included speed restriction devices to limit the vehicles to 25km/h and hydraulic, energy recovery brakes. The distance to the closest customer service office was part of these award criteria, recognising the importance of reducing disruption by minimising time spent travelling and the environmental costs of travelling long distances for maintenance or repair.
