BZL GmbH was founded in 1994 by Barbara Zeschmar-Lahl, who has been managing partner of the company ever since. For larger projects we can rely on a network of competent colleagues.

After many years of freelance work and several teaching positions at the Universities of Bielefeld and Oldenburg, as well as being an authorized manager of a research institute and branch manager of an engineering office, she founded BZL Kommunikation und Projektsteuerung GmbH, based in Oyten near Bremen, in 1994.

The Committee for Biological Agents (ABAS; LINK) has been advising the Federal Ministry of Labour and Social Affairs (BMAS) on occupational safety and health issues relating to activities involving biological agents (microorganisms in the broadest sense) since 1995. The legal basis for this is § 19 of the Ordinance on Biological Agents.
