"G2B BioSolutions and our partners DTU, AU, and Vestjyllands Andel aim to address some of the greatest challenges in sustainable transition, including food waste and the need for green proteins. We are developing a method for upcycling food waste into bioethanol, where the by-products from ethanol production are used to refine new green proteins. The project lays the foundation for Denmark's first waste-free sustainable bioethanol production with CO2 capture. The process of converting waste bread into pure bioethanol has been successfully tested on both laboratory and pilot scales. Protein separation has also been demonstrated on a laboratory scale, achieving 70% protein in the final product. We will scale our solution with experienced partners and design and develop the supply chain for the collection and delivery of waste bread. Additionally, we will further develop the protein feed supplement from the by-product and then test it as feed for farmed fish and pigs. Subsequently, the final optimization and adaptation of a market-ready feed supplement will be achieved. Once the technology is further developed and the feed products tested, we will initiate a commercialization process to establish our biorefinery. The biorefinery will produce sustainable bioethanol, green proteins, and simultaneously capture CO2, resulting in an expected CO2 reduction of 100-150,000 tons CO2eq/year.”
