PURPOSE: A pellet composition and a steel dust pellet are provided to reduce a processing of a steel manufacture waste, and to prevent an air pollution caused by a scatter of a steel dust by transporting with manufacturing the steel dust with a pellet. CONSTITUTION: A pellet composition comprises 90-97 weight% of a steel dust, 2-7 weight% of an inorganic dust binder, and 1-3 weight% of a liquid binder. The inorganic dust binder comprises cement, quicklime, and sodium polyacrylate. The liquid binder is selected in a group consisting of polyvinyl alcohol, polyvinylacetate, and ethylene vinyl acetate. A compressive strength the steel dust pellet is more than 2.0 MPa.
