Through continuity, competence and determination, we have been able to contribute our experience to an ever-widening spectrum of projects. In the meantime, we plan in different areas of environmental engineering, because resource protection, renewable energies and water are elementary building blocks for a desirable future.To do justice to this spectrum, we have decided that from now on we are the Ingenieurbüro Rückert GmbH.

The NatUrgas process is becoming known globally because large quantities of chicken manure can be used. This residual material, a valuable substrate for biogas production, accumulates in truly everywhere.

Thanks to the new digester geometry and optimally adapted agitators, the process impresses with its efficiency and intelligent design. Since then, the concept has been planned and implemented throughout Europe in the range of 300 to 3,000 kW

Claus Rückert founds the engineering office and plans the first biogas plant in which biowaste from Fürth is recycled. In the following years, the engineering office continuously works on improving the fermentation system.
