That actually refers to using bio digesters
for stuff like sewage and compost. Very good idea actually. But nothing to do with catching gas from landfills.

You can catch some gas, and a lot of landfills do, but it doesn't generate much power, it usually runs the landfill site huts and a small amount gets returned to the grid. Plus the point of landfill is stabilising the waste, which means you want it to stop making gas as quickly as possible.

Incineration is a much better idea.
