Around ten potential targets exists. CO 2 emissions avoided with recycling Steel t t Mineral products 3.5 million tonnes of CO 2 emissions Closing of sintering plant will decrease Ruukki s carbon footprint by more than 330,000 tonnes a year This is about 8% of annual emissions on a typical production year
