Vacuum Sanitary System

The 'Darmstadtium' science and congress center in Darmstadt demonstrates the full potential of modern vacuum sanitary systems. The collaboration between planners and implementers at an early project stage resulted in several innovative vacuum sanitation systems from Roediger®, hidden beneath the futuristic shell of the building. Consistent separation of material flows and the use of rainwater ensure highly efficient, water-saving operations, contributing significantly to the Darmstadtium becoming the first DGNB-certified sustainable congress center in Germany.
