The city of Bern was audited again this year by “Energiestadt Schweiz” and the European Energy Award. Again, the city was awarded the Gold Label as the city with the best results in Switzerland. This is why the "Energy City Master Bus" was inaugurated. This is an electric bus from the city’s public transport company BERNMOBIL and will run on line 17 for three months, starting mid November. At the start of the three-month campaign, a delegation from Bern's political, economic and administrative sectors visited the site by electric bus.
Bern Site head Martin Schaeren and Arnold Nigsch, Head of Engineering Services, explained the goal, scope and significance of the innovative project to the visitors. Since 2018, the wastewater has been collected in the collection basin under the close-by "Sempach" park and then transported via special pipeliness to a bioreactor of the local wastewater company on the Aare, where it is converted into biogas. This biogas is used, among other things, to operate public transport, and covers 20% of CSL Behring's gas requirements at the Bern site.
