Hans Oechsner

Dr. Hans Oechsner is a leading academic in agricultural engineering and bioenergy, holding multiple leadership positions including Head of the State Institute for Agricultural Engineering and Bioenergy (Landesanstalt für Agrartechnik und Bioenergie), Managing Director of the Baden-Württemberg Working Group on Agricultural Engineering and Rural Construction (ALB), and Project Leader for the International Graduate College focused on maize-based agricultural systems adaptation to limited phosphate reserves. He teaches advanced courses on biogas technology and bioenergy infrastructure at the Department of Agricultural Engineering in the Tropics and Subtropics.

His research centers on optimizing bioenergy systems and sustainable resource management, with key interests in:

• Advanced biogas production techniques (e.g., mechanical pretreatment, two-stage digestion)
• Phosphorus recovery from organic waste streams
• Valorization of agricultural residues and livestock manure
• Development of circular bioeconomy models for crop systems

Dr. Oechsner's recent publications (2022-2025) demonstrate a strong focus on enhancing biogas plant efficiency, nutrient recycling from digestate, and sustainable biomass utilization. His work consistently integrates full-scale applications with fundamental research, particularly in pretreatment optimization and waste stream valorization.

He leads research infrastructure at the State Institute for Agricultural Engineering and Bioenergy, coordinating teams working on large-scale biogas optimization and agricultural waste management. His projects frequently involve international collaborations and industry partnerships.
