BOTTOM ASH

Bottom ash is the residue from municipal solid waste incineration which is also called slag or incinerator bottom ash (IBA). In contrast to the past when slag was dumped, current technology enables bottom ash processing plants to recover valuable materials. But also transform the residue slag into useful materials. At NM Heilig, we have engineered machinery and installations to treat slags contributing to zero waste management.

APPLICATIONS OF IBA

As a result of incineration, waste facilities generate bottom ash (IBA). Thanks to the latest technology applied in NM Heilig machines, this IBA can be processed into an aggregate (IBAA). This material is suitable for earthworks, pavement construction, and the production of asphalt for roads and waterways. It can replace natural aggregates.

VALUABLE METALS CAN BE SEPARATED

Recovery of valuable metals is just as important for recycling companies to earn money from processing. The aluminum and heavy metals are highly valuable materials to recover from the slags.
the metals are turned into raw material for high-quality re-use at melters.

The sorting and cleaning systems NM Heilig builds and supplies, are applied for separating:

• metals (through magnets)
• non-metals (non-ferrous separator)
• various fractions (screens)
