Remanufacturing is an industrial process that takes a used product or component, disassembles and restores it, and returns it to like-new or better-than-new performance. It keeps more material, labor, and design value in use than ordinary recycling.
Green steel is a broad term for steel made with much lower greenhouse-gas emissions than conventional coal-based blast furnace production. It can involve more scrap recycling, renewable electricity, hydrogen direct reduction, carbon capture, process efficiency, and cleaner industrial heat.
Friction stir welding is a solid-state joining process that uses a rotating tool to soften, stir, and forge metal along a joint without melting the workpieces. It is especially important for aluminum alloys, transportation structures, shipbuilding, rail cars, and aerospace tanks.
