Many isolated algal components will need to be (bio) chemically converted to match the exact application needs. A simple example is the conversion of isolated fatty acid triglyceride oils into methylesters for the production of biodiesel. Here, the required (transesterification) conversion technology is readily available at Wageningen UR. Some optimization is needed to determine optimal conversion and application conditions, given the particular triglyceride ‘blend’ produced by the algae. For the unique aliphatic, long chain oils produced by species like Botryococcus braunii, conversion to biofuels requires a dedicated approach. For all major biomass streams including algae, the conversion to energy, energy carriers, chemicals and materials is a core expertise of AFSG-Biobased Products. Mastered technologies include chemical, biochemical (enzymatic) and fermentative processes. For thermochemical conversions and appropriate matching of biomass-based combustion engine fuels and energy plant feedstock, we collaborate with our strategic partner ECN.
