Birgir Norddahl is a Professor at the Department of Green Technology within the Faculty of Engineering , University of Southern Denmark (SDU). His research focuses on membrane technologies for sustainable processes in food and waste valorization, including biogas upgrading, anthocyanin extraction, and ammonia recovery from manure. Key projects: Probiofa (sustainable bioactives), GRoW (green reverse osmosis), ReUseWaste (nutrient recovery). Active in membrane-based solutions for biofuels, juices, and waste-to-resource systems. Research Interests revolve around membrane fouling, process intensification, and circular economy applications. His work integrates chemical engineering principles with environmental sustainability. Article Trends highlight advancements in: Anthocyanin recovery from berry pomace using enzymatic and membrane techniques. Biogas upgrading via membrane separation and microbial processes. Ammonia recovery from agricultural waste using membrane contactors. Process modeling for cost-effective waste valorization. Teaching includes courses on chemical process design and energy systems. He has supervised projects like TEK-ReUseWaste and XD-CPD1. Labs & Teams collaborate on membrane distillation, ultrafiltration, and biorefinery systems, notably with the Membrane Filtration Forum in Food Processing and the BIOREK® concept.
