Application Center for Wood Fiber Research HOFZET

Technical Equipment

At the location in Hanover, the HOFZET, in cooperation with the Institute for Bioplastics and Biocomposites of the Hanover University of Applied Sciences and Arts, operates a technical center - built in 2016 - as well as diverse laboratories focusing on the fields of plastic and fiber-composite technology. As a member of the Fraunhofer Project Centre Wolfsburg, we operate further facilities on the lightweight-construction campus Open Hybrid LabFactory in Wolfsburg.
