 · Ash within cement kilns gets vitrified, is rendered inert and harmlessly remains within the cement. Unfortunately cement kiln operators tend to be quite selective in the quantity and type of waste that they want, and generally they do not accept all waste. Therefore there is always a niche that incineration should occupy within a sound waste ...
