Technology Description<\/strong>
<\/strong>Pilot 2 focuses on establishing a centralized circular hub that transforms wastewater treatment from a disposal process into a resource recovery engine. Located within the CIIP (Cicli Integrati Impianti Primari)<\/b> service area in Italy, this pilot demonstrates how municipal and industrial wastewater, along with sewage sludge and organic waste, can be valorized to produce safe irrigation water, renewable energy, and high-quality bio-fertilizers.
The solution integrates Nature-Based Solutions (NBS)<\/b> with advanced thermal drying and thermo-chemical processes<\/b> to close the loop on the water-energy-food nexus.<\/p>

Value Chain 1<\/strong><\/p>

This value chain addresses water scarcity by refining treated wastewater to high-quality standards suitable for agriculture and ecological restoration.<\/p>

  • The Process:<\/b> Wastewater from the Treatment Plant (WWTP) undergoes tertiary treatment via a Nature-Based Solution (NBS)<\/b> module (e.g., constructed wetlands\/phytoremediation) for refinement.<\/p><\/li>

  • Safety & Monitoring:<\/b> A robust “Water Reuse Feedback Loop” utilizes real-time probes and analysis by UNIVPM Research Laboratories<\/b> to ensure the water meets strict safety standards (LD 39\/2023 and MD 185\/2003).<\/p><\/li>

  • End Use:<\/b> The refined water is distributed to the Flora-horticultural district of Acquaviva-Grottammare<\/b> for crop irrigation and used for restoring local natural systems.<\/p><\/li><\/ul>

    Value Chain 2<\/strong><\/p>

    This value chain valorizes the solid by-products of the water treatment process (sewage sludge) and other organic wastes.<\/p>

    • Supply Chain 2.1 (Energy):<\/b> Sewage sludge and organic waste undergo anaerobic co-digestion<\/b> to produce biogas. This biogas is converted into renewable energy to power the treatment facilities, reducing external energy dependency.<\/p><\/li>

    • Supply Chain 2.2 (Bio-fertilizers):<\/b> The solid digestate is combined with dried harvested plants<\/b> (biomass collected from the NBS in Value Chain 1). This mixture undergoes thermal drying and thermo-chemical processing to recover nutrients (N, P, K), creating a high-value bio-fertilizer distributed to local farmers as a sustainable alternative to synthetic fertilizers.<\/p><\/li><\/ul>
