The invention provides a method to transform large quantities of waste glass into useful ceramic products by a low-cost manufacturing process. The major steps of the method consist of dry preparation of glass powder, granulation with a non-aqueous organic binder system, dry pressing with adequate green strength, and firing at low temperatures. Water and clay are not required in the processing, which eliminates problems that were encountered in the past. Only one firing step is needed with a low peak firing temperature of about 750 DEG C. The method conserves energy and natural resources compared to clay-based traditional ceramic manufacturing. High-quality impervious ceramic products with only a small amount of porosity can be produced by the invention.
