Abstract
Incinerator ashes, which is obtained after treating municipal solid waste, incinerator ashes or its plasma vitrified slag is made into mineral fibers. Cullet is added during manufacturing the mineral fibers for conditioning. The mineral fibers thus obtained have a good strength and could raise value of recycled product. In addition, it could reduce impact of the incinerator ashes to the environment and environmental protection is achieved.
