Abstract Some vegetable wastes contain relatively large amounts of silica. One of the most promising examples is rice husk. Since rice is a major crop among many of the developing countries, it is available in large quantities. Its ash can be produced without using expensive fuels—such as in the case of Portland cement. During incineration, heat is released which could eventually be ...
