GZQ

What GZQ does

GZQ GmbH is a privately held German certification body (GmbH) headquartered in Saarbrücken, Saarbrücken, Saarland, operating as a DAkkS-accredited certifier since its founding in 1998. The company delivers third-party certification and auditing services for management systems and regulatory compliance, covering ISO 9001 (quality), ISO 14001 (environmental), ISO 50001 (energy), ISO 45001 (occupational health and safety), AZAV (labor market services under SGB III), EfbV (waste management companies under the German Disposal Specialist Companies Ordinance), AltfahrzeugV (end-of-life vehicles), ElektroG (electrical equipment), and End of Waste quality management under EU Regulations 333/2011 and 715/2013 for scrap materials. Beyond DAkkS accreditation, GZQ holds Technical Monitoring Organization (TÜO) authorization from the Saarland state authority for EfbV and operates under an independent supervisory committee (Lenkungsausschuss) drawn from industry and science to preserve impartiality, which is a regulatory requirement for certification bodies.

The business is a professional services firm with a sales-led, direct go-to-market. Engagement is initiated via downloadable application forms on gzq.de, quote-based pricing that varies by certification type, company size, number of sites, and scope, and on-site audits conducted at client locations across Germany and Europe. The customer base spans small and medium enterprises through large multi-site corporations, with end markets concentrated in manufacturing and industrial companies, waste management and disposal, education and training providers, and a long tail of service-sector clients. Revenue is project-based and tied to multi-year surveillance and recertification cycles, with named dedicated auditors and project managers assigned per standard.

GZQ is led by sole managing director Thomas Scherer, with two Prokuristen heads of division (Martin Busch for Management Systems Certification and Anja Weiser for AZAV) and a senior team of qualified auditors holding Dipl.-Ing. credentials. Firmographics indicate 6 employees, while other inputs cite approximately 30 staff including auditors, project managers, quality management, IT, accounting and HR functions; this discrepancy is unresolved in the source material. The company has no subsidiaries, no parent, no disclosed funding rounds, and no public listing. Geographic footprint is Germany and Europe, with no claimed global presence.
