Andreas Lemmer

Andreas Lemmer serves as a Privatdozent (equivalent to Associate Professor) at the University of Hohenheim, where he holds a scientific staff position at the State Institute for Agricultural Engineering and Bioenergy. He actively teaches core courses including Fundamentals of Agricultural Engineering, Process Technology of Biogas Production and Utilization, and Project Design of Plants for Renewable Resources for the upcoming Winter Semester 2025/26.

His research centers on advancing bioenergy systems through biogas optimization and renewable fuel production. Key focus areas include enhancing methane yield from challenging feedstocks like horse manure using mechanical pretreatment, developing machine learning models for anaerobic digestion stability prediction, and creating resource-efficient bio-LNG production chains. His work bridges agricultural engineering, environmental technology, and sustainable resource management with strong practical implementation in full-scale biogas facilities.

Lemmer's recent publications demonstrate a clear trajectory toward industrial-scale bioenergy solutions, particularly in integrating agricultural residues into circular economy models and optimizing process economics for grassland biomass utilization. His work consistently addresses real-world implementation challenges in biogas technology and renewable fuel production chains.

He leads significant research initiatives including the Hohenheimer Biogasforum 2023 and industrial research projects on bio-LNG/CNG production chains for bus operations using manure and organic residues. Current projects focus on resource-efficient bio-LNG production processes developed in collaboration with the State Institute for Agricultural Engineering and Bioenergy and the Field of Agricultural Engineering in the Tropics and Subtropics.
