Abstract
Disclosed is a method and an apparatus used in said method, to produce aggregate products from waste material streams. The method comprises combining an encapsulation material with waste materials to form a mix suitable for granulation. This mix is then feed to a granulation means to form particles having a size suitable for thermal treatment in a bed thermal processing means, which can be a fluid bed system or a spouting bed system. In the bed thermal processing apparatus the particles are converted into an aggregate product.
