About

Day 8 is specializing in the extraction of Rubisco protein from discarded agricultural leaves, transforming agricultural waste into a sustainable, high-quality protein source. By upcycling biomass that would otherwise be discarded, Day 8 enhances the efficiency of the agriculture industry and provides food manufacturers with an essential sustainable ingredient. Their process yields a taste-neutral, off-white protein powder that is not classified as an allergen, boasts high digestibility, and offers superior functional properties such as foaming, gelling, solubility, and emulsification. This innovative approach not only contributes to climate action by improving the efficiency of land, water, and energy usage but also offers growers an opportunity to generate incremental profit by valorizing existing leaf residue.
