    Abstract : Concrete is the second most used material in the world just after water. A drawback is that it is mostly based on Portland cement, which has an extremely high carbon footprint reaching a staggering 900 kg/tonne. The carbon dioxide emissions related to the production of the Portland cement accounts for nearly 8 % of the global total. READ MORE

    Abstract : The efficiency in use of reducing agents in blast furnace (BF) ironmaking has been significantly improved over the years. At most blast furnaces, auxiliary fuels are injected to replace some of the coke. To further reduce carbon consumption, prevention of losses and modification of raw materials or process conditions are required. READ MORE
