What is the carbon footprint of the steel fabrication process?
This is something that each fabricator must determine for their operations. The British Constructional Steelwork Association (BCSA) has developed a common methodology for calculating the carbon footprint of the steel fabrication process. Initial evidence from a selection of carbon footprinting assessments indicates that the answer will generally be of the order of 0.3 tonnes CO2 per tonne of fabricated steelwork. Is there a lot of waste material from steel production? Corus’ processes have been refined over many years to ensure that the consumption of materials within them is optimised. Although a high level of conversion efficiency is achieved, a small amount of waste will inevitably be generated. The vast majority of ferrous waste is re-incorporated immediately back into the steel production chain. Uses have been found for many of the other wastes and by-products in other sectors of industry. For example about 3 million tonnes of ground granulated blast furnace slag (GGBS) is used an
