CRETUS-USC CONTRIBUTION
Researcher Arsal Tehseen from the CRETUS group at the University of Santiago de Compostela (USC) took part in the International Conference on Sustainable Energy and Resource Use in Food Chains – CYPRUS 2025, held in Cyprus. This international forum brings together leading experts in sustainability, bioeconomy, and energy efficiency, and has become a key platform for discussing the ecological transition of the agri-food sector. The 2025 edition focused particularly on circularity, clean technologies, and the valorisation of agricultural and food waste.
Dr. Tehseen delivered an oral presentation titled “Assessing the environmental implications of manure waste management and its application in purple hydrogen production”, where he shared the results of an ongoing study exploring the use of livestock manure from Spanish farms to produce turquoise hydrogen. Using life cycle assessment (LCA), the research evaluates the global warming potential of this alternative compared to conventional hydrogen production routes (grey, blue, and green). Preliminary findings suggest that decentralised turquoise hydrogen production—directly on farms—could significantly reduce indirect (scope 3) emissions and generate solid carbon as a valuable by-product. The study offers promising insights into the role of this technology in the decarbonisation of the livestock sector.
