Anaerobic digestion (AD) has the potential to catalyse shift from a linear circular economy. However, effective treatment and management of both solid (DSF) liquid (DLF) digestate fraction require adopting sustainable technologies recover valuable by-products like energy, biofuels, biochar, nutrients. This study reviews state-of-the-art advanced for DSF DLF valorisation, using life cycle assessment (LCA) techno-economic analysis (TEA) in integrated (IDM). Key findings highlight these technologies' mitigating environmental impacts management, but there's need improve process efficiency, especially at larger scales. Future research should prioritize cost-effective eco-friendly IDM technologies. review emphasizes how LCA TEA can guide decision-making promote agricultural practices. Ultimately, boost resource recovery advance economy principles, enhancing economic sustainability AD processes.

This study investigates the suitability of Phragmites australis (reed) biomass deriving from a surface flow constructed wetland (CW) to produce three compost types: reed (RC), mixed + potato cuttings (PC) and liquid anaerobic digestate (DC), promote both resource circularity soil carbon sequestration. The composts were tested over 60 days on lettuce at two levels in combination or not with NH4NO3 (at same kg N ha−1 loading), along reference (Chem) an unamended control (Ctrl). plant tissue dry weight load was determined, relative efficiency (N-RAE %) calculated. On pot soil, total labile (TOC, CL), management index (CMI) δ13C evaluated. Pot test showed that PC100 yielded best (g pot−1) (3.0) > DC100 RC100 (2.5 1.6) ≈ chemical (3.8). A similar pattern detected 50% pot−1): PC50 (2.9) DC50 (2.7) RC50 (2.4). N-RAE (%) reflected this pattern: (60) (21) (10) (76) (53) (52). analyses well performed TOC CMI, comparison Ctrl (+42% +13%), suggesting positive impact C amelioration. No significant differences observed for distribution, did influence microbic metabolism differently. These results indicated harvested CWs can represent interesting material composting, combining sequestration nutrients recycling potential these system, addition their wastewater treatment capacity.
