Development of a bio-based and reusable flocculant for harvesting microalgae based on cellulose nanocrystals

Microalgae are a new source of biomass for biofuel and food and feed applications. Harvesting of microalgae is currently challenging and expensive. Flocculation could be a environmentally friendly and cost-effective way to harvest microalgae. Extensive knowledge on the microalgal surface chemistry and properties, as well as of the flocculant properties is required to achieve efficient flocculation. This project situates in obtaining that knowledge and using it for the development of re-useable cellulose-based flocculants.
