The chef dude here (it's a little bit cramped and confusing), is making yukkuri "knife-shaved noodles", a Chinese specialty.
In the bottom half, after painstakingly harvesting as much of the yukkuri's skin as possible with a checkmark-shaped piece of sheet-metal/blade, he tosses them into his refuse pile as trash, absolutely in agony. The skin "noodles" fly into a pot of boiling water to be cooked.
Very graphic and absolutely pleasing yukkuri torture; kudos to the artist. I hope there would be a follow-up pic of the trash-yukkuri suffering in more detail, but this is quite nice anyways.
He doesn't mean trash as in gutter trash yukkuri or trash/scumbag attitude. Trash as in, they get thrown away like common garbage. On a related note, mixing gutter trash yukkuri off the streets with livestock is a bad idea; trash/scum personality is fine as there's nothing physically wrong with them.
Very nice indeed, only complaint is if the guy making these would do them larger and in higher resolution/quality...
I believe most images are shrunken down into cell-phone friendly sizes, hence the low resolution on these. I know Jun in particular has a low-res version for phones and so does kariloader.
