The wastewater treatment plants (WWTPs) must be transformed into Water Resource Recovery Facilities (WRRFs) in view of a more sustainable approach focusing on the circular economy concept. Different to WWTPs, WRRFs have as major goal not only meet legislation limits but also recovery resources such as: treated water for reuse, carbon, nutrients, biopolymers etc. In boosting application real WWTs, WRRF at Palermo University (UNIPA) has been built within EU project: Achieving Wider-Uptake Smart Solutions. This study is aimed demonstrate feasibility resource from UNIPA WRRF. Specifically, effects (TWW) and recovered nutrients faba bean were assessed. Results showed that aligned with legislation. Further, TWW increased soil electrical conductivity adversely impacted plant growth. However, biochar zeolite effectively mitigated these adverse effects. Microbiological investigation revealed both broad pods seeds analysed did host pathogenic bacteria.

The products of an advanced sewage sludge fermentation process can be used to generate polyhydroxyalkanoates (PHAs), precursors bioplastics considered excellent candidates for replacing petroleum-derived plastics. aerobic feast-anoxic famine cycling strategy has proven efficient method enriching microbiota with PHA-producing microorganisms. This work evaluated the effect different carbon nitrogen ratios (C/N) 3.5, 2, and 1 g COD/g N modulating structure improve PHA production. study was executed on a pilot plant scale using wasted activated as organic source derived from oxic-settling anaerobic that collects wastewater various facilities at University Palermo campus. production performance monitored over three experimental periods characterized by C/N ratio. results showed lower reduced 20, 24, 26 % w/w PHAs COD/N values 1, 3.5 N, respectively. In parallel, metataxonomic analysis revealed higher abundance microorganisms ratio such Proteobacteria, specifically Betaproteobacteria. addition, increase in fungal diversity decrease decreased. Thus, these findings demonstrate utility metataxonomics elucidating relationships between operating conditions, bacterial achievement specific outputs. insights gained this demonstrated positive correlation ratios, microorganisms, yields.
