Proven quality and expertise

Both the construction regulations and environmental requirements require numerous tests for secondary aggregates such as GRANOVA incinerator bottom ash. This provides proof that the material properties required for the planned application are met.

The principle of the quality assurance system

Secondary aggregates are subject to quality control system

In-house monitoring in the form of factory production control, together with independent external monitoring, form the quality assurance system. This system applies to natural aggregates as well as for secondary aggregates, so that a comparability for both materials is given. more

What does IBA contain? Visit our laboratory!

In order to monitor the quality of mineral constructon materials and to optimise the recycling rate of ferrous and non-ferrous metals from incinerator bottom ash (IBA), numerous tests are carried out in our plants on a regular basis. Our laboratory film gives an impression of the testing scope.

Proven quality

Certificates of conformity for our secondary aggregates GRANOVA in accordance with the German Secondary Aggregate Directive (EBV) can be found on the German MEB Quality website
