Swedish Innovation Revolutionizes Grain Drying Using Nobel-Winning MOF Technology

Swedish innovator Kurt Hansson is pioneering a revolutionary grain drying technique by applying the 2023 Nobel Prize-winning metal-organic framework (MOF) technology developed by Professor Omar M. Yaghi. This new method, developed in collaboration with Swedish research institutions including Linköping and Lund Universities, promises a drastic leap in energy efficiency and sustainability for agricultural grain drying.

Metal-organic frameworks are molecular structures with cavities capable of trapping gases, facilitating chemical reactions, and enabling novel industrial applications. Hansson’s project, named Leandry, utilizes MOF 303 to dehumidify air, turning the dry air itself into the primary agent for drying grain, instead of relying on conventional warm or cold air drying techniques.

Testing of a prototype machine in September 2024 demonstrated the capability to remove approximately 27 liters of water daily from grain, using merely 0.6 kWh of energy per liter of water extracted. This figure is a significant improvement compared to traditional drying systems, which consume roughly 1.5 kWh per liter. The energy reduction translates into potential cost reductions of up to 90%, bringing promising economic and environmental benefits for Swedish grain producers.

The Leandry innovation was initially presented at Elmia Lantbruk in 2022 and gained further exposure at the Agritechnica trade fair in November 2023. With support from the Swedish Board of Agriculture, this project not only stands to improve the grain drying process but also serves as a practical application of cutting-edge Nobel-recognized scientific discoveries.

Agtech Sweden expert Per Frankelius remarked that the Nobel Prize recognition is elevating interest among investors in both water harvesting technologies and Hansson’s sustainable grain drying vision. The successful integration of MOF technology in agriculture marks a significant stride in harnessing advanced materials science to address energy demands and sustainability challenges in Sweden’s agricultural sector.

As of October 9, 2025, the Leandry project continues progressing toward commercialization, aiming to transform grain drying efficiency in Sweden and potentially internationally, offering a compelling example of science-driven innovation enhancing traditional industries.
