Abstract: A process to manufacture a waste material composite and article is described. One embodiment comprises waste material particles or fibers mixed with water to form a mash, blending a chemical binder with the mash, mixing in a cementious material and a filler agent. In another embodiment the chemical binder is added after the filler agent is added, but prior to the cemetious material. In yet another process, the mash which comprises water and paper particles is mixed with wheat residue and the chemical binder and then formed into a paper-wheat article which is pressed until cured. Still, in yet another process, rubber particles are heated, blended with the chemical binder, blended with cement, cooled, blended with ash, formed into an article and pressed until cured to form a cement-rubber composite article. The filler agent comprises calcium hydroxide, hydrated lime, carbonated lime or ash.
