Internationally acclaimed secondary aggregates
granova® IBA is also available outside of Germany. As an internationally registered trademark, we produce special granova® qualities and grading curves for concrete and asphalt in the Netherlands, for example. Our activities extend to Europe and Asia.
Fields of application
As a future-oriented alternative construction material made of municipal solid waste incineration bottom ash, granova® is ideally suited for making construction projects more economical.
The applicable regulations for substitute construction materials and secondary aggregates such as incinerator bottom ash are extremely complex. In addition to the environmental specifications of federal states, technical construction regulations have to be observed. A uniform federal regulation in form of the Secondary Aggregates Directive will replace these rules in August 2023.
The regular quality surveillance of secondary aggregates such as granova® IBA with corresponding test certificates serves as proof of compliance with environmental specifications and technical requirements.
New technologies for added value
The basic principle of IBA processing is quickly explained. However, in order to be able to produce special qualities and achieve higher recycling rates, we use special additional technologies.
Handbook on secondary aggregates
The handbook explains German regulations for the use of various secondary aggregates in road construction and earthworks.
