Although our municipal green waste gets converted to compost, I recently found out that there is a food waste to energy plant in my city [1]. Going by their numbers, a home can be powered for a year with 25 tonnes of food waste, or 70 kg a day.
The two largest sewerage treatment plants also capture and generate electricity from biogas [2].
I think in Germany this is pretty standard (both turning organic waste into biogas and collecting biogas at sewage treatment facilities).
And tbh not treating organic waste as some form of resource should be considered a scandal these days, and the only valid discussion to be had should be how to use it (my bet would be that in the long term that will be chemicals and not energy). There is legitimately a lot of talk about the landuse issues of bioenergy, but using organic waste doesn't have any of those problems. It should be an absolute nobrainer.
