Recycling of waste refractories in European glass industry

The European glass industry uses more than 100,000 tons per year on kilns with a service life of 5 to 8 years. The dismantling of these kilns will generate thousands of tons of waste refractories, most of which will be sent to technical deposit centers (CETs) or proprietary dumps. To help users reduce the amount of waste refractories sent to landfills, VGG is working with glass companies and kiln demolition companies to establish waste acceptance standards and develop new products made from recycled materials.

At present, 30% to 35% of the silicon bricks removed after the kiln has been used can be reused to make two kinds of silica bricks, including the silicon wedge bricks and light heat insulation used in the working pool or regenerator roof. Silicon bricks. The first European factory for the comprehensive recycling of abandoned refractories specialised in the treatment of waste refractories from the glass industry, steel industry, incinerators and the chemical industry with a recovery rate of 90%. A glass company cuts the wall of the kiln's melting pool as a whole, succeeded in using the effective part of the pool wall, and removed the glass adhered on the surface of the used ZAS brick, and cracked the brick with a method of quenching, broken and grinded. After screening, different size aggregates and fines are obtained to produce cheap high-performance castables and iron channels.
