<p>The process uses recycled materials. In order to obtain a product which is environmentally acceptable, it is proposed that the waste materials are first subjected to a first high-temperature process, preferably incineration, pyrolysis or the like, at a temperature above 500 DEG C, and the intermediates originating from this process, i.e. slag, ash and dust, and/or incineration residues, for example sludge, originating from any downstream flue gas or effluent cleaning operation are then, if necessary after drying to constant weight, converted, in a further high-temperature process, into glassy and/or sintered end products in the form of granules, mouldings or the like at a temperature corresponding to the melting point of eutectic glass batches, additives, for example salts, being added in order to improve the melt flow and to reduce the amount of eutectic.</p> |
