Abstract
Rubber-base wastes, such as tires and industrial rubber wastes, may be disposed of, without pretreatment thereof, by contacting the wastes with molten metallurgical slag on the site of the production of the slag. The molten slag causes flash thermal decomposition of the rubber-base wastes in a non-polluting manner. The solidified slag products obtained are useful for soil improvement or construction work consolidation.
Claims6
A process of disposal of rubber-base wastes by flash thermal decomposition at high temperatures, comprising pouring molten metallurgical waste slag at a temperature above 1,250.degree. C., which slag has been removed from a metallurgical furnace, onto the rubber-base wastes at the production site of said slag, the weight ratio of the rubber-base waste/molten slag being between 5 and 15%.
