Dustman → It is formed from "dust" (from Old English *dūst*, meaning fine particles of matter) and "man" (from Old English *mann*, meaning a person). A dustman is a person who collects dust and refuse, typically in the context of waste management.
Think of a person ('man') who deals with 'dust' — that's why a dustman is someone who collects dust and waste.
