      abstract     = {Regarding the omnipresent topic of climate change,
                      establishing a bio-economy appears reasonable, but requires
                      critical analysis of its products. This project-specific
                      study (project Bio²) presents previously unknown
                      environmental impacts caused by the novel production of
                      biosurfactants (rhamnolipids (RL) and mannosylerythritol
                      lipids (MEL)) based on substrates from sugar industry
                      (molasses and sugar beet pulp) using Life Cycle Assessment
                      (LCA). Identifying critical impacts and processes (e.g.,
                      extraction agent production) reveals optimization potentials
                      for the considered forward-looking process designs. Based on
                      surfactants’ specific cleaning performance, environmental
                      impacts vary substantially for RL and MEL. Primary causes of
                      MEL productions’ lower environmental impacts are
                      advantageous microbial properties and process designs.
                      Substrate choice does not play an essential role. An
                      analysis of realistic yield changes and comparisons with
                      conventional surfactants sharpens the view on the
                      development position of the chosen surfactants. In
                      particular MEL shows environmental benefits compared to
                      today’s oleo-/petrochemical produced surfactants.
                      Identified optimization options (e.g., increased agent
                      recycling) and yield increases could strengthen especially
                      the advantages of MEL. Summarizing, the results show
                      advantages of MEL compared to RL to some degree, indicate
                      weak points of current processes and highlight favorable
                      options for future design of RL and MEL production,
                      regarding their environmental impact.},
