Even better, once the gas was purified and converted into biomethane—or even liquefied into fuel—it could be stored and used efficiently. If they succeeded in producing liquid biogas fuel, they wouldn't need to worry about fuel shortages for their vehicles anymore. On top of that, biogas fuel produces far fewer emissions than fossil fuels, making it not just practical but also environmentally sustainable.
This was why Duke was fully invested in making the biogas farm a reality.
Before the apocalypse, Duke had already been deeply involved in a biogas venture, which was why he had so much knowledge about it. He had teams researching the potential of biogas and its many benefits, particularly its ability to produce clean energy while also promoting the use of natural fertilizers.
