rubbish, junk, trash, waste, scraps
屑 centers on worthless leftover material: rubbish, junk, trash, waste, or scraps. It describes things that are broken, discarded, or of no value.
屑 combines 尸 (a body or dwelling) with 肖, which likely contributes the sound and the idea of small or fragmentary things. The exact historical development is uncertain.
Inside a dwelling 尸, small fragments 肖 pile up as worthless scraps and rubbish.
For セツ, imagine a set of broken junk: set -> セツ, and all those scraps are worthless.
