Metaphorical meaning of ゴミの分別 Context: Riku is a young boxer in Baba's gym. Yanagi, an older boxer, used to be in Baba's gym too in the past, but he moved to another gym because he was not satisfied with Baba's methods. The two, Riku and Yanagi, are now talking about Baba. > Yanagi: > > Riku: **** … First of all, I am not sure about the meaning of , but I guess that Yanagi is saying that Riku too is not satisfied. Then, the literal meaning of is "garbage sorting", but I can't really imagine how it could fit the context, so I guess it was used with a metaphorical meaning that I was not able to find on dictionaries. Also, I am not sure about the subject of , is it Riku or Baba? Here you can see the whole page. Thank you for your help!

* (), literally "(listing) one or two won't suffice", is a set phrase that effectively means "there are quite a few".
* Assuming is used for the first time in this page, it is **not** a common metaphor for something. It just means "separation/sorting of garbage" here. is "I (=Riku) want him (=Baba) to sort garbage", implying that's the main complaint about Baba. That is, Riku euphemistically denied Yanagi's speculation and implied he was basically satisfied with his environment.
