As one of Europe’s largest suppliers of public transport, Keolis is responsible for the buses that serve the centre of Stockholm. But these aren’t just any buses – they run 100% on renewable fuels such as biogas. And a significant proportion of the fuel comes from Stockholmers’ visits to the toilet. Keolis felt this was a detail worth advertising while at the same time wishing everyone a Happy New Year.


For a limited time, we’ll be running on lobster and champagne.

In Stockholm city centre we don’t run on any old shit. We run on yours. We use 100% renewable fuels, such as biogas recovered from the sludge created by treating agricultural waste, manure and industrial and food waste. But also from the wastewater that will soon contain the results of so many New Year dinners. Happy travels. And Happy New Year.
