Title: MICROALGAE BIOREFINERY FOR BIOFUEL AND VALUABLE PRODUCTS PRODUCTION
Abstract:
The invention relates to downstream processing of microalgal biomass to produce different products in a biorefinery process. The invention establishes interconnected stages from harvesting of microalgal biomass, following several productive processes, including alternatives to use the remaining biomass. The invention allows improving the overall downstream process by adapting each stage of the production process for a complete microalgal biomass use producing various added-value products of commercial interest: proteins, biodiesel, and biogas or biomethane. In addition, the invention includes wastewater reutilization alternatives to be reused in the same processes. The invention has application in processing biomass such as microalgae and other biomass types, for the production of biofuels and co-products.
