In Germany alone, about 12 million tonnes of food go to waste each year. From an energy point of view, this food waste is very valuable, as biowaste can be made into sustainable energy in biogas plants and then fed into our electricity and district heating grids. We will show you how such biowaste can be optimally recycled today with the help of state-of-the-art grinding and separation technologies.


Products & Machines
