Valorising of waste streams to recover nutrients from grass and seaweed biorefineries Ghent University
The objective of this study is to retrieve mineral nutrients present in the digestate, considered as a valuable by-product after the AD, upcycle them to purified and stable fertilising products, creating added (economic) value to the overall production chain. Grass and seaweed, which will be considered novel substrates in terms of nutrient recovery from their respective digestates will be studied.
