A method for manufacturing a metal-resin composite includes preparing a mold including a first mold forming a housing portion and a second mold movable with respect to the first mold, housing an extruded material in the housing portion, arranging resin material on the first mold, moving the second mold to form a cavity defined by the extruded material and the mold, and filling the cavity with the resin material. In the filling, a protrusion of the extruded material is brought into close contact with the housing portion or its peripheral edge by molding pressure applied from the mold to the extruded material, and the cavity is disconnected from a gap between an inner surface of the housing portion and the extruded material.

A method of manufacturing a sustainable article is provided. The method includes mixing a waste material with a binder. The binder includes a catalyst configured to enable the binder to bind the waste material into the sustainable article. The method also includes curing the binder and the waste material into the sustainable article. The binder and the waste material are cured into the sustainable article outside of a press.
