D2.2 Selection of case studies for nutrient recovery and bio-based fertiliser production and methodology description

Deliverable 2.2 presents the methodology and results of the screening and selection process used to refine an initial inventory of more than 150 nutrient recovery and bio-based fertiliser technologies into a refined shortlist of 35 cases. This exercise, conducted under Task 2.2 of Work Package 2, represents a key step in the FertiCovery project’s aim to identify and promote the most promising technologies for substituting mineral fertilisers with sustainable alternatives.
