Andreas Krieg planned and constructed his first biogas plant in 1986. At that time he was still a student. He kept on working in biogas business and finished his diploma work about chicken manure digestion in Tunisia, Africa.
Starting in 1991 he worked for several engineering offices in Germany. Between 1991 and 1998 he planned and constructed more than 30 biogas plants, mainly for agricultural purpose. These references are located mainly in Germany but also in Lithuania, Slovakia and Seychelles. In addition he was responsible for many studies, investigations and trials in Ghana, Thailand, Ukraine and many countries more.
He finished his last job in 1998 and became founder and 50%-owner of Krieg & Fischer Ingenieure GmbH in 1999. Following structural shifts, 2006 the Big Dutchman became 50%-owner. Andreas Krieg changes his position from general manager to the leader of the competence team.

Torsten Fischer was working as assistant engineer at Technical University of Hamburg-Harburg when he started a Research & Development Project in anaerobic digestion. This was in 1993.
In 1995 he began to work in industry and was busy in industrial-scale biogas plants. Until 1998 he was responsible for process technology, quotation, engineering and construction of big biogas plants. The focus of his work were big centralised co-fermentation plants as well as plants for biowaste and kitchen waste.
He finished his last job in 1998 and became founder and 50%-owner of Krieg & Fischer Ingenieure GmbH in 1999.
In 1998 the ATV appointed him as a member of the ATV-working group "Vergärung" [digestion] and in 2002 as a member of the ATV-working group "Biogasspeicherung" [biogas storage]. Since 2002 he is active in the working group "safety" of the German Biogas Association.
