DIEMEN, the Netherlands – BASF SE and Purac, a subsidiary of CSM nv, have begun negotiations to form a joint venture for the production of bio-based succinic acid. The companies have been conducting research under a joint development agreement on bio-based succinic acid since 2009. The complementary strengths in fermentation and downstream processing led to the development of a sustainable and highly efficient manufacturing process based on a proprietary microorganism. The demand for succinic acid is anticipated to grow strongly in the coming years.

The newly developed process combines high efficiency with the use of renewable substrates and the fixation of the greenhouse gas CO2 during production. This results in a positive eco-footprint and makes bio-based succinic acid an economically and ecologically attractive alternative to petrochemical substitutes. The employed microorganism Basfia succiniciproducens is a natural producer of succinic acid and can process a wide variety of C3, C5 and C6 renewable feedstocks, including biomass sources.
