Investments in new plant technology mean increased recycling efficiency – resulting in higher recycling quotas and improved construction material qualities

Waste as a resource

Municipal Solid Waste Incineration (MSWI) is an effective means of reducing landfill through the incineration of unrecyclable household waste. MSWI produces a by-product known as incinerator bottom ash (IBA). One tonne of waste usually produces about 250 kg of bottom ash, which is a heterogeneous material that comprises varying proportions of glass, ceramics, brick, stone, ferrous, and non-ferrous metals as well as other non-combustible organic matter.

granova®: The steps to a high quality secondary aggregate

The conditioning of granova® consists of the classification of the mineral content, separation of the ferrous and non-ferrous metals and removal of organic matter. The expertise of making a building material out of waste lies in the detail, i. e. in the type, order, and number of different process steps.

After an appropriate ageing period, granova® complies with the technical and environmental requirements for use as a secondary building material. The suitability is determined with a strict quality control system and includes regular tests of material, chemical and geometric-physical properties as well as further tests on-site and on behalf of the customer.
