Anaerobic Codigestion of Municipal Wastewater, Landfill Leachate, and Crude Glycerin: Process Stability and Methane Yield Assessment Using a Screening Design [PDF]
Water Environ ResAnaerobic codigestion of municipal wastewater with landfill leachate and crude glycerin can achieve near‐theoretical methane yields (0.349 L NCH4/g tCODadd). An optimal mixture of 2% leachate and 1% glycerin was identified, as higher glycerin content negatively impacted performance, highlighting the criticality of substrate balance for energy recovery.
