Coupling anaerobic digestion with gasification pyrolysis
Downloadable (with restrictions) This review aims at summarizing the literature for the coupling of the biological process of anaerobic digestion (AD) with one of three thermal processes gasification (Gs) pyrolysis (Py) and hydrothermal carbonization (HTC). These thermal processes are investigated as pre and/or post treatments for AD aiming at reducing its main drawbacks.

Biogas is a mixture of CO2 and CH4 produced by a consortia of Bacteria and Archeae operating in anaerobic digestion (AD) plants. Biogas can be burnt as such in engines to produce electricity and heat or upgraded into biomethane. Biomethane is a drop-in fuel that can be injected in the natural gas grid or utilised as a transport fuel. While a wide array of biomass feedstock can be degraded into
