explain the technologies that have been used (for these biogas
and leaking methane issues), and whether or not they have wide

advantage or disadvantage makes any difference, given the
catastrophic consequences of sewage pollution, methane leaks, and
energy independence/scarcity due to the Russian invasion of
Ukraine.
