“…x−3 from complex streams containing other ionic species will contribute to the realization of a more sustainable circular nutrient economy (Li et al, 2015;Ye et al, 2020;McCartney et al, 2021).

Ion-exchange membranes (IEMs) are utilized in numerous established, emergent, and emerging applications for water, energy, and the environment. This article reviews the five different types of IEM selectivity, namely charge, valence, specific ion, ion/solvent, and ion/uncharged solute selectivities. Technological pathways to advance the selectivities through the sorption and migration mechanisms of transport in IEM are critically analyzed. Because of the underlying principles governing transport, efforts to enhance selectivity by tuning the membrane structural and chemical properties are almost always accompanied by a concomitant decline in permeability of the desired ion. Suppressing the undesired crossover of solvent and neutral species is crucial to realize the practical implementation of several technologies, including bioelectrochemical systems, hypersaline electrodialysis desalination, fuel cells, and redox flow batteries, but the ion/solvent and ion/uncharged solute selectivities are relatively understudied, compared to the ion/ion selectivities. Deepening fundamental understanding of the transport phenomena, specifically the factors underpinning structure-property-performance relationships, will be vital to guide the informed development of more selective IEMs. Innovations in material and membrane design offer opportunities to utilize ion discrimination mechanisms that are radically different from conventional IEMs and potentially depart from the putative permeability-selectivity tradeoff. Advancements in IEM selectivity can contribute to meeting the aqueous separation needs of water, energy, and environmental challenges.

“…The theoretical minimum energy for P recovery, governed by thermodynamic principles, is substantially lower for the feed of sourceseparated urine (i.e., the liquid is diverted away from black water and isolated) compared with other wastewaters (McCartney et al, 2021). For instance, recovery of orthophosphate from urine is ≈13− 34% less energy-intensive than treated wastewater effluent (McCartney et al, 2021). This is because urine is rich in P (total orthophosphate, TOP = 19− 48 × 10 − 3 mol/L), (Fittschen and Hahn, 1998;Larsen et al, 2013;Simha and Ganesapillai, 2017;Udert et al, 2003a) whereas treated wastewater effluent is over 1− 2 orders of magnitude more dilute.…”

“…Most approaches for recycling-oriented source separation involve the use of waterless/dry toilets that either collect urine and feces together or separately (Larsen et al, 2013;Londong, 2016). Besides the potential to significantly increase nutrient recovery, the benefits of a separate collection of human excreta comprise inter alia the decreased use of freshwater and the reduced harm to aquatic environments through high nutrient loads or dilution of trace substances (Morgan, 2007;Remy and Jekel, 2008;Bisinella de Faria et al, 2015;Bradford-Hartke et al, 2015;Ishii and Boyer, 2015;Kjerstadius et al, 2017;Hilton et al, 2021;Larsen et al, 2021;McCartney et al, 2021).…”

Recycling nutrients is essential for closing nutrient loops within a circular economy. Using locally available resources such as human excreta to produce bio-based recycling fertilizers can substitute mineral fertilizers and thereby promote environmentally friendly food production. To better understand the fertilizer potential and nitrogen value of human excreta, three novel and safe recycling products were evaluated in a field experiment. Two nitrified urine fertilizers (NUFs) and one fecal compost were applied alone or in combination, and compared against the commercial organic fertilizer vinasse. In addition, the uptake of pharmaceuticals was assessed for treatments with compost application. White cabbage (Brassica oleracea var. capitata f. alba) was cultivated in plots in three different soil types (sand, loam or silt) treated with the fertilizers according to plant needs and mineral soil nitrogen content. The two NUFs resulted in marketable yields similar to those of vinasse in all soil types. Combining fecal compost with a NUF led to increased marketable yield compared to compost alone. The highest yield was recorded from the sandy soil, where vinasse and NUF treatments led to comparable yields, as expected in organic productions systems (up to 72 t ha−1). The cabbage yield and total aboveground fresh biomass followed the following trend in all soils: NUFs ∼ vinasse ≥ compost + NUF ≥ compost. Nitrogen uptake in the cabbage heads and total biomass was significantly higher in sand (69.5–144 kg ha−1) than loam (71.4–95.8 kg ha−1). All compost treatments alleviated the effect of soil type and resulted in comparable nitrogen uptake and yield in all soil types. Plant uptake of pharmaceuticals (Carbamazepin) was higher in sand than in loam, and concentration in the edible part was lower than in the outer leaves. In conclusion, NUF alone appears to be a promising successful fertilizer substitute in horticultural food production. The combined application of NUF and compost led to slightly lower crop yields, but may increase soil carbon content in the long term, promoting climate-friendly food production.
