Robot Sludge Mole

Thermo-Systems Gmbh of Germany developed a solar drying system for sewage waste sludge.
Drying the waste reduces the weight to one tenth of the original water-filled state. This dramatically reduces the problem of disposal.

The solar drying takes place in a greenhouse environment. To effectively dry, the sludge must be turned regularly to allow all the waste to be exposed to the air.

The 'Electric Mole'works 24 hours a day to ensure that no sludge remains un-turned and all the sludge gets dried evenly.
