Yellow is the new brown: The lower of these 10-day-old bananas is protected by a cellulose coating. Image: Manifesto Films, Lidl Schweiz - Empa and Lidl Switzerland have jointly developed a cellulose protective coating for fruit and vegetables. The novel coating is made from so-called pomace - squeezed fruit and vegetable peels. The innovative project can reduce packaging and prevent food waste. Plastic packaging in grocery stores protects fruits and vegetables from spoilage, but also creates significant amounts of waste. Together with the retailer Lidl Switzerland, researchers have now developed a protective cover for fruit and vegetables based on renewable raw materials. For this project, Lidl chose Empa as a partner because Empa had decades of research experience with cellulose products.
