Investigation of recycled building materials

Chemical analyses as the basis for environmentally compatible recycling

The high-quality recycling of mineral waste and its re-use as secondary raw materials (recycled building materials) makes a considerable contribution to conserving resources by saving primary resources and thus also to climate protection. As a rule, quality-assured recycled building materials are produced by mechanical processing such as crushing, screening, sorting and classifying mineral waste. Subsequent installation takes place in technical structures for earthworks, road and path construction.

In particular, soil and groundwater protection regulations must be observed. Adverse changes in the groundwater quality and the occurrence of harmful soil changes must be ruled out permanently. To date, there is no nationwide uniform regulation on the assessment of indemnity and the use of recycled building materials depending on it. Most federal states have issued their own regulations, which are based on a set of technical rules of the Federal/Länder Working Group on Waste (LAGA M20). A solution promises here the introduction of the so-called substitute building material regulation, as a part of the planned coat regulation.

We analyse the following materials:

  • Concrete
  • brick
  • Road breaking/asphalt
  • track ballast
  • cinders
  • ashes
  • sands
  • Waste containing gypsum

SYNLAB gehört zu den wenigen Prüfeinrichtungen, welche neben der aquatischen Ökotoxizität auch die terrestrische Ökotoxizität und Prüfungen mit dem Wasser/Sediment-System anbieten. Darüber hinaus führen wir ökotoxikologische Bewertungen wie z. B. die Einstufung nach den Wassergefährdungsklassen durch.
