Am Aichaberg in Hohenburg machen Wissenschaftler aus Klärschlamm besten Diesel

Der Aichaberg bei Hohenburg ist eigentlich nur als Standort des Krematoriums bekannt, in dem viele Menschen aus der Region nach ihrem Tod verbrannt werden. Doch direkt nebenan haben Wissenschaftler jetzt Großes geschaffen.

Der ehemalige Rallye-Weltmeister Walter Röhrl ist das Gesicht des Projekts, bei dem aus Klärschlamm hochwertiger Diesel-Treibstoff wird. Und natürlich hat er den auch getestet. Sein Urteil: "Es gibt keinen Unterschied zum normalen Diesel."
