A primary fuel catalyst used to combust a secondary fuel, the primary fuel comprising the gases produced by water electrolysis. When secondary fuels are combusted by the primary fuel, the by-products include heat, water and other more stable by-product materials. When the secondary fuel is a hazardous waste or a radioactive material and either is bound to thermite before combustion, the by-products are no longer hazardous or have significantly reduced radiation levels after one or more passes. Embodiments of the present invention relate to the method for accelerating the decay of hazardous and/or radioactive waste products, and more particularly they relate to the nuclear transmutation of heavy radioactive elements into lighter ones with shorter half-lives and then finally to stable daughter products. Therefore, the invented process relates to reducing the long-term toxicity of hazardous and/or radioactive waste and to, an economic and effective process facility for doing so.
