With the help of the SOLARTIGER^® technology you can dry different kinds of sludge f.e. sewage sludge, digestate. In the full automatically operation of the low maintenance drying plant the aim of the drying is to achieve the highest efficiency as possible.

Since 2001 we engage in solar drying of sewage sludge.

Since 2005 we operate a solar drying plant in Allershausen (near Munich). Rothmaier is also the owner of the solar drying plant.
