METHOD AND APPARATUS FOR THE TREATMENT AND RECOVERY OF MINERAL FIBER OR GLASS WASTE

摘要

The present invention relates to a method of treating waste comprising introducing a glass or mineral fiber substrate (7) contaminated with organic materials into the chamber (1) of a furnace by means of a conveyor belt (4), subjecting it to a gas consisting of a neutral gas and between 0 and 10% by volume of oxygen, heated to a temperature below the melting temperature of the waste substrate in order to pyrolyze the organic materials, and recovering the waste substrate. This method has particular application to the recovery of the vitreous material forming the waste substrate, in order to recycle it for use in a glass melting furnace.
