<p>PROBLEM TO BE SOLVED: To improve quality of glass granule by a method wherein organic matter stuck to the glass is enabled to be removed even though a washing process is not especially provided. SOLUTION: A crusher 1 wherein glass waste G is charged and the glass waste G is pulverized to glass granule F and discharged, a water storage tank 30 storing water in which microbes decomposing organic matter stuck to the glass granule F is mixed, a crusher water feed pipe line 31 feeding water in the water storage tank 30 into a crusher 1, a sinking water tank 33 wherein the glass granule F together with water discharged from the crusher 1 is temporarily stored, and the glass granule F is made to sink, a carrying part 34 carrying the glass granule F sinking in the sinking water tank 33, and a return pipe line 35 returning the water in the sinking water tank 33 to the water storage tank 30, are provided. Then, the water is circulated with the crusher water feed pipe line 31 and the return pipe line 35. The organic matter can be decomposed with the microbe thereby, disposal efficiency is extremely improved, and quality of the glass granule F can be achieved to be improved.</p> |
