Ash from waste incineration

Getting the best out of the rest

After incineration, the incombustible components of the waste and the inert materials produced in the process (those which are no longer reactive) remain. Together, these are referred to as ash or slag.

Germany produces about 78 kg of slag per capita every year. Slag is the predominant waste material after the incineration of household waste, and on average it contains 1-3% non-ferrous metals and 5-15% ferrous scrap, while the rest consists of a mixture of minerals, glass, ceramics and other components.

 

Process

BHS systems technology ensures maximum efficiency in breaking up agglomerated materials and in the subsequent refining of metallic raw materials. Depending on the application and objectives, various BHS machines are used:

Trials at the BHS technical center

The selection mainly depends on the maximum size of the feed materials. To arrive at the optimal machine configuration, we will perform trials at the BHS technical center together with you and your unique feed material. Register for a trial here!

Non-ferrous metals in incinerator bottom ash are turned into valuable resources

BHS-Sonthofen planned and implemented a turnkey plant for the processing and refinement of metals derived from waste incineration plant slag and other metal-bearing fractions. Recycling machines from BHS are core components of both processing lines, as they allow for efficient shredding. This order from Switzerland is the largest ever for the Recycling Technology division.
