Leftovers from the fish industry might become a valuable raw material in the future. A German company has developed a system for recycling shrimp shells and other fish waste to create oils for the food production industry. The oils are rich in omega-3 fatty acids, which help prevent cardiovascular problems. The aim is to minimize waste from the fish-processing industry. Other potential leftovers are turned into a powder that is high in protein and may have anti-inflammatory properties.
