Abstract
A construction article manufactured from recycled waste materials is provided which efficiently utilizes a variety of ordinary refuse materials in providing a high-strength article. The article may be constructed of either ash as well as unburnt material filler and tack combined with a plastic binder, or alternatively metal, glass, paper and cloth may constitute the filler to be combined with the plastic binder. The plastic binder may be of a variety of polymers which may be melted to fuse the waste material together. The article is preferably provided with complimentary recesses and projections on opposite sides whereby similar articles may be combined to interlock with one another and bonded by the use of an organic solvent.
