Grass2Algae

The Grass2Algae operational group aims to evaluate the use of grass juice for growing microalgae as an additional source of income for farmers.

The Grass2Algae operational group explores utilising grass juice from roadside or low-quality grass as a nutrient source for cultivating microalgae, offering additional income opportunities for Flemish farmers. Grass juice, comprising 40-60% of grass weight, contains essential macro and micronutrients crucial for microalgae growth. Through a pressing process, grass juice is separated from fibers and used as a medium for microalgae cultivation. Initial results suggest that grass juice can serve as a viable nutrient source for producing protein-rich microalgae biomass. However, pH adjustment may be necessary to optimise microalgae growth and minimise microbial contamination. Further pilot-scale studies are warranted to fully understand the potential of grass juice as a nutrient medium for microalgae cultivation.
