Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <p>Heat recovery from hot blast furnace (BF) slag is difficult to achieve but has great potential to recover energy and thereby reduce CO₂ emissions. The objective of this work is to utilise the heat of hot BF slag granulates to generate combustible gas from printed circuit boards. The results showed that this is a possible process and that, after cleaning, the combustible gas could be injected into the BF as a fuel and reducing agent. The new process has advantages over the traditional process in energy saving and pollution emissions.</p> </abstract>
