The REPowerEU plan establishes the production objective of 35 billion m3 biomethane in European Union (EU) by 2030. Biomethane is an excellent energy vector to promote defossilization different sectors within a Power-to-Gas approach. present study evaluates economic and environmental implications producing from biogas generated municipal wastewater treatment plant (WWTP) with capacity 100,000 m3/d 500,000 population equivalents. techno-economic analysis (TEA) life cycle assessment (LCA) were conducted for based on biological methanation process using hydrogen produced water electrolyser. TEA illustrated that electricity price (0–0.20 €/kWh) features important impact cost (0.05–0.23 €/kWhHHV) due high electrolyser consumption. Flexible operation economically feasible at load factors above %, which can be attributed lower capital as factor increases. LCA has global warming (<0.28 kg CO2-eq/kWhHHV) than fossil natural gas when renewable mix 62 %. results highlighted carbon prices under EU Emission Trading System driver countries since could exempted acquire emission allowances. This would provide competitive advantage over considering whole supply chain carrier. Overall, this demonstrates potential become technology future scenarios.

This article investigates the economic and environmental implications of implementing green ammonia production plants in Spain. To this end, one business-as-usual scenario for gray was compared with three scenarios powered different renewable energy sources (i.e., solar photovoltaic (PV), wind, a combination PV wind). The results illustrated that reduced impacts global warming, stratospheric ozone depletion, fossil resource scarcity when conventional scenario. Conversely, implementation increased categories land use, mineral scarcity, freshwater eutrophication, terrestrial acidification. techno-economic analysis revealed featured lower costs than considering moderate natural gas cost. However, became most economically favorable option cost carbon prices increased. Finally, showed developing efficient ammonia-fueled systems is important to make relevant vector entire supply chain (production/transportation). Overall, research demonstrate could play an role future decarbonization scenarios.

The growing human population is increasing the need for crop production, which has resulted in elevated requirements of Nitrogen-Phosphorous-Potassium (NPK) fertilisers. This tremendous demand cannot be sustained on traditional processes, cause significant resource depletion and unacceptable environmental impacts due to their heavy reliance fossil fuels. To overcome this, alternative sources obtain fertilisers have been explored, including recovery nutrients from wastewater waste streams. However, this approach faces several challenges, such as dilution streams, low public acceptance, lack support. With aim surpassing these barriers, present study provides a review existing Research & Development (R&D) projects field, comparing available technologies identify optimal train nutrient recovery: Anaerobic Digestion followed by valorisation digestate (directly or producing P-based P salts, CaP, H3PO4 P2O5) liquid fraction (obtaining struvite, ammonium sulphate/nitrate, reclaimed water). Moreover, an innovative strategy based decentralised treatment separated concentrated streams proposed useful valorising nutrients, developing Strengths, Weaknesses, Opportunities Threats (SWOT) analysis. Finally, non-technological strategies are suggested mainstream valorisation, aimed at overcoming social barriers promoting stakeholder acceptance recycled with associated rejection. Nutrient through source waste/wastewater using optimised seems sustainable addressing current future massive

ABSTRACT Anthropogenic nitrogen fluxes are profoundly altering the global biogeochemical cycle. Better management of these is essential. Recovering from urban wastewater reduces both energy and resources required to produce nitrogen-based fertilizer remove collected. Nitrogen can be recovered in form ammonium sulfate, a common fertilizer. In setting, technology applied target source-separated urine or municipal wastewater. To assess environmental sustainability this approach, study compared life cycle impacts sulfate (through eight different recovery trains) produced by six industrial processes. The results show that wastewater-derived generally has lower potential than industrially most impact categories assessed. for centralized train smallest. contribution analysis shows energy, sulfuric acid sodium hydroxide use major contributors, while background inventory sensitive choice region-specific inventory. future, promising circular economy cities.

Anaerobic digestion (AD) has gained attention in the last decade as a strategic component of circular bioeconomy (CBE), and Life Cycle Assessment (LCA) been used to explore environmental performance prospective AD-biorefineries. A detailed review 76 studies underpinned systematic evaluation hotspots LCA modelling challenges for AD-biorefinery configurations. Crops constitute most frequently feedstocks, while electricity, bioethanol, digestate, animal feed, additives, platform chemicals represent reported products. Feedstock cultivation, energy chemical inputs, biogenic emissions, avoided burdens due product substitution are main drivers performance. However, substitution, biogas upgrading, digestate management carbon cycling is patchy, inconsistent, often inadequately evidenced. Prospective dynamic coupled with transparent scenario analysis could address some these shortcomings, better represent, inter alia, climate mitigation efficacy capture use storage technologies integrated into These findings provide guide practitioners researchers engaged study biorefinery systems other CBE measures.
