Since 1950, Rotie has been providing a sustainable, environmentally-friendly service for recycling deep-frying fat into second-generation energy. This green energy helps to reduce greenhouse gas emissions and the use of fossil fuels. It has more than 35,000 large and small catering and food customers, who are served from seven branches in the Netherlands, Belgium, and Germany. Rotie was part of Simadan Group; thanks to Parcom, Rotie was able to develop independently. This eventually resulted in its merger with Quatra at the end of 2019, creating a robust European market leader.
