Arne GRÖNGRÖFT

Head of Working Group Separation Technologies and Process Design

DBFZ Deutsches Biomasseforschungszentrum gemeinnützige GmbH

Leipzig, Germany

Potential applicant for a funded RTDI project

Enthusiast for separation and purification of biobased products and techno-economic assessment of biorefineries.

My organisation

The Deutsches Biomasseforschungszentrum gemeinnützige GmbH (DBFZ) is a German federal research institution for advancing the sustainable, efficient and integrated utilisation of biomass in material and energy systems. Our vision is the bioeconomy: an economy and energy system that function without fossil resources. Our contribution: biomass is available only in limited quantities and must therefore be used optimally. We identify sustainable potentials, discover new fields of application, and develop innovative processes and technologies – always with a view to economic viability and environmental compatibility. With a wide range of equipment from lab to technical scale and pilot plants, DBFZ findings help shape the technical realisation and validation. These are backed by techno-economic and life cycle assessment, as well as market analyses to push the system to technologic maturity. In doing this, DBFZ research is guided by the United Nation’s Sustainable Development Goals (SDG). The DBFZ is headquartered in Leipzig. As of 12/2025, the DBFZ has 272 employees covered by collective labour agreements. The Supervisory Board of the DBFZ consists of representatives from six energy-related ministries (BMLEH, BMUKN, BMV, BMWE, BMFTR, SMWA).

About me

Head of Working group "Separation Technologies and Process Design"

Efficient separation processes are a fundamental component of modern biorefinery concepts for the production of bio-based products and fuels. We design and develop the integration of multiple process steps into complete separation cascades. For investigations, a wide range of industry-relevant separation equipment for solid-liquid and liquid-liquid separations is available. Using process flow simulations mass and energy balances are calculated, which serve as the basis for techno-economic analyses and sustainability assessments.
