Abstract:

Related to the development of production processes for microbial bio-based surfactants like rhamnolipids and mannosylerythritol lipids a sustainability assessment was carried out within the project Bio². Developments at lab-scale and technical scale built the base for an industrial design scenario of different process chains, whereby exemplary co-products of sugar beet processing were used as substrates. Environmental impacts, economic issues and social risks of defined process chains allowed a classification of different microbial surfactant production options by the assessment of the three dimensions of sustainability. The generated results work as an indicator for further development, provide insights to potential hotspots and allow the estimation of future market positions.
