Steel manufacture

The basic raw material for steel manufacture is either the hot metal from the blast furnace steel scrap or a mixture of both The proportions of material used vary according to the process and the type of steel required Steel can be described in general terms as iron with most of the carbon removed to make it tougher and more ductile There are many forms (grades) of steel each with its

Circular carbon steelmaking

Circular carbon steelmaking enables 'waste' carbon to be used for low emissions steelmaking The practice utilizes sources of carbon which would otherwise be sent to landfill burnt or emitted to the air Examples include blast furnace gases waste biomass and waste wood which has no other use These sources of carbon can be turned into other products or used as an alternative to coke
