The green solution

Pump systems

By a process of homogenisation, pump systems convert kitchen waste and leftovers into a pulpy biomass – directly at the input stations. This considerably reduces the volumes of most wastes. The biomass is then pumped in a closed system into the collecting tank. There it can be stored odourlessly for several weeks at room temperature. The biomass is regularly collected by vacuum – usually every 4 to 6 weeks – and transported to a biogas plant, where it is used directly converted into energy and fertiliser.
