The impatiently awaited construction of the new exhibition centre site at the Stuttgart airport is fully underway. A 100,000 m2 exhibition area and a state-of-the-art congress centre are coming into being. The opening of the new exhibition centre in Stuttgart is planned for the year 2007. The Max Bögl group of companies has installed a residual concrete recycling plant from Bibko, Beilstein (Heilbronn district) for the incidental remaining quantities of concrete and the residual water resulting from cleaning the mobile mixers.
