Fig. 5: BLG AF–Fe membranes versus NF sustainability footprint.
From: An antiviral trap made of protein nanofibrils and iron oxyhydroxide nanoparticles
The factors considered are operating costs (OPEX), investment cost (CAPEX), energy consumption, water recovery, removal efficiency, pressure, public acceptability and environmental friendliness. The scores of technologies in each discriminant are shown by red (low performance), yellow (medium) and green (high performance). The overall sustainability footprint is obtained by a weighted averaging of the score in each discriminant (see the text for details). In this analysis, an industrial grade of BLG, that is, whey, is considered as the source for AF preparation.
