Krieg & Fischer Ingenieure GmbH is Specialised in Biogas Plants

Krieg & Fischer Ingenieure GmbH was founded on 1 January 1999 by Andreas Krieg and Torsten Fischer. We offer a full range of biogas services - from preliminary study to planning and construction through to commissioning.

Andreas Krieg designed and constructed his first biogas plant in 1986. During subsequent years he worked for general contractors and engineering offices. His work focused on agricultural biogas plants. In 1992 Andreas Krieg was co-founder of the German Biogas Association.

Torsten Fischer has worked in the biogas technology industry since 1993. Prior to the establishment of Krieg & Fischer, he worked for two general contractors. His work mainly involved industrial biowaste digestion plants and large-scale co-fermentation plants.

Raphael Thies already works for Krieg & Fischer since 2007. Starting out as an engineer in the field of planning and processing, he now also works in the field of sales. Alongside founder and shareholder Torsten Fischer, Raphael Thies will, as of 2017, take up the position of an additional Managing Director.

Krieg & Fischer therefore has extensive experience in the planning and construction of biogas plants. Our expertise covers one- and two-stage, mesophilic and thermophilic, wet and dry fermentation plants. Liquid manure, dung, renewable raw materials, biowaste, kitchen waste, fats, organic sludges and many other forms of organic waste are treated in these plants.
