Scrap

Scrap is like leftover stuff from making and using things, such as parts of cars, building materials, and extra materials. Unlike regular waste, scrap is valuable, especially metals that are recycled. Not just metals, but other materials can be reused too. Scrap is basically pieces or old items made of wrought iron that can be reused or melted for casting. Scrap can be made of different things like old steel from structures, turning scrap, old rolls, and household iron items like fans, coolers, and cylinders, and other iron waste items.

Furnaces use these scraps to make finished goods, which are then used by other factories as raw materials, like steel ingots and other casting materials.
