Abstract: Disclosed herein is a method for preparing a matrix for vitrifying radioactive waste, including: grinding natural magmatic rocks; and melting the ground product at 1450-1500° C. for 3-4.5 h followed by moulding and annealing to produce the matrix. The matrix includes 45%-65% by weight of SiO2, 9%-18% by weight of Al2O3, 4%-12% by weight of CaO, 3%-10% by weight of MgO, 6%-16% by weight of Fe2O3+FeO, 2%-9% by weight of Na2O+K2O and 1%-5% by weight of TiO2. The matrix is doped with simulated radioactive waste, ground, melted, moulded and annealed to obtain a glass wasteform with good chemical and thermal stability.

Abstract: A disposal method for entirely recycling solid refuse includes the following steps: sorting, crushing, drying, pressing with high pressure to shaped articles, producing charcoal from combustible refuse in high temperature and firing incombustible refuse in high temperature, at last cooling high temperature articles to obtain solid fuel with various shapes and bricks or board used for building. The method achieves entirely recycling house refuse, especial solid refuse. The method recycles solid refuse to obtain fuel and building material with economic value. The method is simple and its processing cost is low.
