ABSTRACT:
A process for producing a ceramic product using sludge ashes comprises the steps of (i) mixing at least ashes obtained by burning a sludge which has been obtained by the treatment of sewage and a plastic ceramic raw material to prepare a first body, (ii) mixing at least a plastic ceramic raw material and a fusible material to prepare a second body, (iii) supplying the first and second bodies into a matrix of a molding machine such that the first and second bodies form a lower, larger layer and an upper, smaller layer which covers the lower layer, respectively, (iv) molding the whole of the first and second bodies into an object with a desired shape, and (v) firing the molding to produce a two-layer ceramic product.
