Environmental regulations for substitute construction materials
Until the enactment of the nationwide regulation in form of the “Ersatzbaustoffverordnung” (Directive on Secondary Aggregates) on 1 August 2023, requirements pertaining to secondary construction materials are applicable on a German federal state level. With regard to the recycling possibilities of mineral waste, most federal states refer to the 1997 and 2003 guideline LAGA M20 of the “Länderarbeitsgemeinschaft Abfall” (i.e. the waste working group of the federal states), but there are also federal states with their own regulations, e.g. North Rhine-Westphalia (NRW) has created its own legal basis for use in applications and quality monitoring through a number of decrees.
How exactly the individual material qualities are defined, which parameters are determined and how – the details can be found in our German handbook.
