Carbon-negative biomethane fuel production: integrating anaerobic digestion with algae-assisted biogas purification and hydrothermal carbonisation of digestate

This paper presents a new integrated process for producing carbon-negative biomethane fuel which combines anaerobic digestion of sewage sludge with biogas purification, algae generation and carbon capture. Biogas CO2 is recovered through absorption into sodium carbonate solution, producing bicarbona...
