Application Center for Wood Fiber Research HOFZET

Technical Equipment

At the location in Hanover, the HOFZET, in cooperation with the “IfBB – 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.
