He drives so that others can drive: Stefan Wehrheim and his Actros L transport between five and six million litres of AdBlue® every year. He takes 24,500 litres per trip. Business with AdBlue is only one of the pillars of ROTH ENERGY. For a long time now, the energy suppliers from Giessen, Hesse, have been big guns in the sector on a national level. Today, a total of around 350 vehicles drive for ROTH ENERGIE. And for good reason: with 53 in‑house petrol stations, six fuel depots and external customers on top of all that – orders are always coming in thick and fast.
