In this research, the upgrading technology and policy trends for biogas were examined with a focus on the European Union (EU). Depending on the capacity of the biogas upgrading facility investment costs are different. In addition, biogas upgrading technology-specific energy demand is lowest in the amine scrubber process. Organic waste met the sustainability criteria. Also, the energy content was four times larger, and the results showed that the utilization value was significant. Through cogeneration, and it can secure various markets. Because of these advantages, various policies are being promoted in the EU. In the future, South Korea needs to model its biogas policy after the upgrading technology and policy trends in the EU, and it should strive to create a market for biomethane.
