The SolarBatch concept is a batchwise process for drying sewage sludge, digestate and various other substrates.

The material to be dried is brought into the drying hall, usually by wheel loader or push-off trailer. Using free solar energy and with the help of the Electric Mole, a fully automatic turning robot, and a ventilation system, the material is uniformly dried to the desired DS content. Removal is again carried out by means of a wheel loader. Due to its simplicity and robustness, the Thermo-System SolarBatch concept is the most widely used worldwide.
