technology
Anaerobic digestion
Microbial breakdown of organic residues into biogas, upgraded to grid-injection biomethane.
Where it's used
Advanced biofuels (SAF, renewable diesel & biomethane)
Drop-in fuels from waste oils, crops and residues — a stack from feedstock to certified SAF, renewable diesel and grid-injection biomethane.
Anaerobic digestion & biogas from MSW
Industrial-scale anaerobic digestion of municipal solid waste (MSW) to produce renewable natural gas (RNG), drastically reducing methane emissions from landfills while providing baseload decarbonized energy for heavy transport and grids.
Biogas and anaerobic fermentation
Microbial anaerobic digestion of farm residues, energy crops and food waste into biogas, upgraded to grid-injectable biomethane (RNG) — a regional biogas industry distinct from MSW-focused digestion.
Municipal wastewater bio-treatment
Biological treatment of municipal sewage — activated sludge, membrane bioreactors, nitrogen/phosphorus nutrient removal, anaerobic digestion of sludge to biogas, and water reuse — a mature, globally deployed remediation value chain distinct from industrial effluent treatment.
Sustainable marine biofuel (biomethanol, bio-LNG)
Bio-methanol and bio-LNG for shipping decarbonization — biomass-gasification methanol and anaerobic-digestion liquefied biomethane burned in dual-fuel marine engines, cutting well-to-wake CO2 by 60-95% under IMO and FuelEU Maritime regulation.
