What is green steel?
Steel has become an essential commodity in modern society - used in everything from our cars and our buildings to the cutlery we use to eat our dinner. Unfortunately, the process used to traditionally produce steel (mining iron ore and combining it with carbon in a blast oxygen furnace) releases a huge amount of CO2. So, is there a cleaner way of producing steel? In this episode, we chat to Prof Barbara Rossi about 'green steel', and how it could improve the sustainability and resilience of the construction industry.
