Water and wastewater infrastructure is a major energy consumer an important source of global greenhouse gas emissions: on average, 10.6 kg CO2/m3 water consumed. The European Environment Agency in 2019 estimated these emissions from treatment operations Europe alone at over 25 MtCO2eq. Increased demand (in terms volumes quality) the sector raises expectations future increases if appropriate measures will not be undertaken. Many companies utilities associations have been or are developing plans to achieve net zero industry-wide basis by 2050, some cut 50% last ten years. About half energy-related facilities could significantly abated applying existing technologies, close 95% this objective achieved negative cost with proper innovation strategies. This paper examines discusses issues, possibilities, technologies that considered planning reduction WW-related GHG holistic view entire sector, based recent literature review.

Excess biological sludge processing and disposal have a significant impact on the energy balance economics of wastewater treatment operations, receiving environments. Anaerobic digestion is probably most widespread in-plant method globally, since it stabilizes converts biosolids organic matter into biogas, allowing partial recovery their embedded chemical energy. A considerable number studies concerning applicable techniques to improve biogas production, both in quantity quality, include pre-treatment strategies promote disintegration aimed at release solubilisation intracellular compounds, inorganic/biological amendments improving process performance, thermal pre-treatment. As for in-process amendments, iron, micro macro-nutrients, ashes from waste incineration nanoparticles addition been studied improvement enzymatic reactions. Recently, use electrically conductive materials has credited with possibility accelerate stabilize conversion substrates methane. The increasing generation its relative biomethane content by interfacing anaerobic bioelectrochemical systems was also postulated. This review addresses research gap surrounding integration novel technologies, particularly systems, enhance production methane enrichment. While existing focus feasibility, mechanisms, benefits such remain underexplored. By critically evaluating current state art, this identifies potential stability, while highlighting key challenges needs advancing these technologies toward practical implementation.
