Valorising nutrient-rich digestate: dilution, settlement and membrane filtration processing for optimisation as a waste-based media for microalgal cultivation

The ALG-AD project has published a new scientific paper entitled “Valorising nutrient-rich digestate: dilution, settlement and membrane filtration processing for optimisation as a waste-based media for microalgal cultivation” in the latest issue of the journal Waste Management.

The paper focuses on physical pre-treatments of digestate to optimise this product as a medium for microalgal cultivation at a large-scale. The article collides the results of one year of research conducted at the laboratory, but also in the pilot-scale facilities at Swansea University, with the collaboration of Bioscience and Engineering teams. 

“The article is a summary of the background work necessary to develop the ALG-AD technology at a larger scale, and findings from the paper were implemented at the production pilot to optimise the whole process,” says Fleuriane Fernandes, lead author of the article.
“We are glad to have published this work at a scientific level, as it shows that the science behind the ALG-AD technology is validated by the wider scientific community, showing a promising future for the development of similar technologies based on a circular economy concept”.
