D2.6 – Report on Nanofiltration and Selective Crystallisation Processes

The research presented in the deliverable focuses on the recovery of high-purity water, salts, and minerals, usually rejected in desalination processes. Salts of Mg(OH)2, CaCO3, and KCl recovered in the study resulted in such a good quality, that they can be used as nutrients for Bio-based Fertilisers.

D 2.5 – Report on ABC- BioPhosphate: multi-functional biofertiliser and adsorbent

The study, focused on the dairy industry, aims at fully upcycling unexploited waste water stream acidic whey. The reuse of effluent water for moisture control of cattle manure, co-compost, and close the nutrient cycle resulted to be a viable solution for efficient upcycling of the unexploited dairy industrial waste water acidic whey.
