Freeganism ethic and biogas

[u/WandellWix]

Hello.

I am a freegan and I always was thinking that it is ethically good as food is not being waisted. Lately, I started reading about biogas and how food from shops which weren't sold are processed into biogas.

​

My question:

Is freeganism still ethicall, when taking food intended for biogas?

Biogas, although from renewable sources, is essentially methane, it's just not from petroleum.
