Blast furnace slag is created as a by-product in the metal industry and it is important to find new applications for it. Currently, it is used as a foundation material for road construction and other less refined solutions. There is a demand for the recycled material in the chimney industry, for example, where the bricks used in certain types of chimneys are currently made of Icelandic lava stone. The carbon footprint of the stones, shipped from a great distance and separately quarried from the earth, is high.
