The aim of this project is to demonstrate two technically and commercially innovative concepts, to boost B2B (business-to-business) cooperation and obtain sustainable production of raw materials by efficient use of resources. The proposed solution transforms certain WWTP effluents into algal biomass with added value by recovering nutrients, using solar energy and CO2capture from the biogas plant. The B2B business model will ensure that the project comes into contact with different types of biomass processing companies to find a market for the products thus obtained.
