Plasma Physics Revolutionizes Food Production: Eight-Year Project Yields Sustainable Solutions
A groundbreaking eight-year research initiative, “Physics for Food,” has concluded, demonstrating the potential of plasma physics to transform food production from farm to table. The project, funded by the Federal Ministry of Research, Technology and Space (BMFTR) and presented at a final event in November 2025, offers promising chemical-free alternatives for crop protection, grain storage, and water treatment, paving the way for a more sustainable and resilient food system.
The project, initiated by the Neubrandenburg University of Applied Sciences and the Leibniz Institute for Plasma Research and Technology (INP), focused on developing physical processes to enhance sustainability across the entire food value chain – from seed treatment and cultivation to storage, processing, and greenhouse technologies.
Plasma-Based Crop Protection: A Chemical-Free Future
One of the most significant breakthroughs lies in physics-based crop protection. Researchers discovered that plasma treatment effectively reduces disease-causing pathogens on seeds, performing as well as traditional chemical treatments. Field trials with winter barley showed a remarkable 10-40% increase in emergence after plasma treatment, coupled with a roughly 5% boost in grain yield. Furthermore, an INP-developed decontamination process secured a European patent in October 2025, signaling a major step toward commercialization.
“These results demonstrate that plasma processes can be seamlessly integrated into existing crop protection strategies,” stated a senior official involved in the project. “They not only promote plant growth but also reduce stress, leading to healthier and more productive crops.” Field studies consistently revealed variations in leaf infestation and yield, providing strong evidence for the practical viability of these applications.
Revolutionizing Grain Storage with Plasma Technology
The project also tackled the critical issue of grain storage, offering a compelling alternative to conventional chemical pest control. Plasma technology proved capable of eliminating molds and insect pests, such as the grain beetle, in laboratory settings. Building on this success, researchers developed both a conveyor belt system for direct plasma treatment of grain and a method for utilizing plasma-treated air within silos.
A practical test utilizing a 30-ton grain silo successfully optimized treatment parameters. The technology has garnered significant interest from farmers seeking chemical-free storage solutions, indicating a high level of acceptance.
Sustainable Water Treatment for Agriculture and Industry
Addressing water scarcity and pollution, the “Physics for Food” project developed innovative physical methods for water treatment. Stationary and mobile demonstrators were created for treating both wastewater and process water, applicable to industries like food processing and agriculture. The combination of filtration, ultrasound, ozone, UV radiation, and plasma proved highly effective in reducing pollutants and microorganisms. Collaborations with the Anklam sugar factory and the Störtebeker Braumanufaktur provided real-world testing grounds for these technologies.
Notably, a large-scale hydroponic system housing over 3,000 plants was established within a vertical farming environment. Here, plasma-treated water achieved hygienic standards comparable to those achieved with conventional chemical agents, while simultaneously replacing the need for nitrogen fertilizer and promoting robust plant development.
From Lab to Market: Commercializing Sustainable Innovation
A key characteristic of the “Physics for Food” project was its focus on transferring research into practical applications. Physically generated plasma is inherently chemical and residue-free, resource-saving, and environmentally friendly – attributes highly valued by both farmers and consumers.
With funding from the EXIST program, the project’s findings on sustainable grain storage are being translated into a marketable technology. A new company is slated to be founded in Brandenburg to commercialize this innovation. “The proximity to application and suitability for business transfer were central to the project’s design from the outset,” explained a company release.
The success of “Physics for Food” underscores the power of interdisciplinary collaboration between science and industry. The project has fostered a strong network of expertise in physical processes within the agriculture and food sectors, resulting in twelve additional collaborative projects and approximately 30 new regional and supra-regional partnerships. This collaborative spirit promises to drive further innovation and solidify the region’s position as a leader in sustainable food technologies.
