Microclean, a Norwegian company specializing in hygiene solutions for the food industry, has secured a patent for its microwave-based technology designed to disinfect plastic products.
The innovation is particularly targeted at the aquaculture sector, where the rise of listeria poses significant challenges.
The technology, developed in collaboration with SINTEF, NOFIMA, the University of Karlsruhe, and Weiss Industri Teknik, has undergone industrial testing at salmon producer Nordlaks in Norway. Results indicate that the process removes 99.99% of bacteria, including listeria, from conveyor belts, boxes, and containers, according to a press release from the company on Monday.
Unlike traditional methods, Microclean’s approach uses only microwaves and water, eliminating the need for chemicals. The technique not only cleans surfaces but also penetrates the plastic to eradicate bacteria within the material.
“This represents a new hygienic standard for the industry,” said Dan Roger Olsen, CEO of Microclean. “Bio-film and bacteria, including listeria, can be effectively neutralized in under 1.5 minutes, even on plastic products with structural imperfections.”
The technology has received both national and international recognition, winning first prize for innovation in Norway and third prize globally.
