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.

Only with optimal feeding and appropriate dosing of the feed material can the grinding plant be operated efficiently. Tietjen offers three options for feeding with the air-gravity separator (AGS series), the drum feeder (DA series) and the vibratory feeder R.
