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

摘要

The process for the treatment of waste comprising a substrate of glass or of inorganic fibres in combination with organic matter consists in introducing the waste (7) on a conveyor (4) into the enclosure (1) of a furnace, in subjecting it to a gas heated to a temperature below the softening temperature of the substrate of the waste and consisting of inert gas and of 0 to 10% by volume of oxygen to pyrolyse the organic matter and in recovering the substrate from the waste. …Application to the recovery of vitreous matter forming the substrate of the waste with a view to its being recycled into a glass- melting furnace. ……
