The impact of direct air carbon capture on climate change

From what I can recall, landfills produce more methane than any other process. How about we build a carbon capture next to every landfill, divert the methane and burn it to run the DAC?

Landfills do collect and burn methane. Those pipe like structures you see sticking out of a completed landfill are part of the process.

TIL. Now we just need to execute the second part of his plan to capture the carbon from the energy produced

Or capture the methane, upgrade it and run generators/cars/busses of it. It's existing tech

Why bother for landfills?

If the landfill can generate electricity that would otherwise be generated, it will convert the CH4 more efficiently than a bus and you don't expand energy upgrading it.

You can power the bus with the already high quality CH4 you extracted from the ground that you would have otherwise burned in to generate the electricity.

Buses have different power requirements than cars; they need a lot more range because they run throughout the day.

I was reading somewhere that in buses in cold climates, heating is actually what eats up all the energy in an electric bus. ICE buses just use the waste heat from a combustion engine.

This scheme is used in real life in Czech Republic

Or you just burn the trash directly.
