The European steel industry generated about 21.4 million tons of slag in 2012 resulting from steel making. About 24% is not being reused, representing a severe environmental problem in Europe, but also a huge amount of available material for potential recycling. RESLAG will face this environmental problem by providing 4 eco-innovative industrial alternative applications to valorise the steel slag.
