Environmental and technical regulations for use of IBA as secondary aggregates

When using secondary aggregates, the construction regulations and environmental specifications must be observed

Environmental protection and technology

A solid set of regulations and far-reaching environmental legislation define the framework in which granova® incinerator bottom ash (IBA) is produced and used. These regulations include construction technology as well as environmental requirements, which may vary between federal states, but which, on closer inspection, follow a common line. In the near future, this common line will also be expressed in a nationwide directive, the Directive on Secondary Aggregates (Ersatzbaustoffverordnung), which is currently under development.

Technical background for secondary aggregates

Road construction with IBA: Structural fundamentals of substitute construction materials

Through the use of sophisticated production methods, granova® IBA is turned into a construction material with outstanding structural properties. Similar to natural aggregates, the technical requirements of the respective fields of application in road construction and earthworks are decisive for the applicability of secondary aggregates. more

Presently: Federal environmental requirements

Environmental protection defines the range of possible applications for secondary aggregates such as IBA

At present, there is no uniform national German regulation with regard to the environmental compatibility of substitute building materials or the installation of these secondary materials in technical constructions or on top of or into soil. This regulation is currently still in progress with the so-called Directive on Secondary Aggregates. Thus, for the time being, the federal-state-specific regulations such as LAGA Notice M20 are applicable. mehr

Future nationwide secondary aggregates directive

The draft Directive on Secondary Aggregates was accepted by the German Bundestag in March 2017 and subsequently submitted to the Bundesrat on 17 July 2017. Its approval is pending. The introduction of the Directive and the new version of the Federal Directive on Soil Protection and Contaminated Sites are intended to create a uniform and legally binding basis for the proper and safe recycling of mineral waste.
