As there is no exclusive regulation for biogas and biomethane, historically, the Brazilian regulations that govern these markets have more connection with other fuels, such as ethanol and biodiesel than with natural gas. This occurred because the laws that dealt with gas dealt only with natural gas of fossil origin, excluding other sources.
Biomethane production in Brazil has grown and gas is cited as a source for decarbonization in the transport sector. According to the survey carried out by Abiogás, there are 25 biomethane plants expected to start operating by 2027 with projects in which investment exceeds R$ 1 billion. With this, it is expected to reach 2.3 million m/³ day of produced volume.
