Accreditations and conformity assessment bodies
The waste department is responsible for conformity assessment bodies that test waste for waste declaration covered by the Waste Management Act (KrWG), which is set out in ordinances on methodology and analytical methods. For the determination of hazardousness in particular, and for the decision on disposal/waste recovery, there are regulations in place which require testing by accredited laboratories. For sampling, chemical-physical, biological and preventive hygiene waste parameters, approximately 400 laboratories are currently accredited in accordance with DIN EN ISO/IEC 17025 or DEN EN ISO/IEC 17020.
Laboratories that test waste for disposal in accordance with the German Landfill Ordinance (DepV) and deposit (mining law) or thermal disposal must be accredited. For sewage sludge, biowaste, waste oil and wood waste, there are notifications of the competent German state authorities based on accreditation which necessitate additional requirements for accreditation. These are defined in the Waste specialist module developed by the Federal/Regional Working Group on Waste (LAGA), and are reviewed by specially appointed assessors.
Benefits of accreditation
This accreditation not only certifies the competence of conformity assessment bodies, it also independently confirms maintenance of this competence by means of regular assessments.
