<p>In a method for disposing of fibre cement waste products, in particular asbestos cement products, the products are simply coarsely crushed (less energy expended) and the resulting product is inserted in the entry zone of a revolving tubular kiln at a minimum temperature of 800 DEG C, preferably adding it to the normal stream for main materials used in cement production. The advantage lies in that, on the one hand, less energy is used and that, on the other hand, protection measures against fibres coming free whilst being coarsely crushed are easier to draw up than when crushing the products into a flour.</p> |
