Chromatography and bipolar electrodialysis
Eurodia has an unrivaled mastery of these two technologies, which are key to bio-based chemistry.
There are many reasons to reduce our dependency on hydrocarbon-based chemistry: cutting greenhouse-gas emissions by using renewable raw materials, minimizing environmental impacts at source, developing materials with new properties for product innovation, creating value and jobs, quickening the shift to the circular economy, and meeting consumer expectations. Valorizing biomass, a renewable source of carbon, is a major issue for the industry of the future.
To ensure the sector’s sustainability, it is vital to industrialize the selection and purification of molecules valorizable from biomass, and especially plant-based molecules, using production processes with high yields and low environmental impacts. For several years now, Eurodia has been leading this challenge, with solutions for purification and fractionation that combine various types of membrane filtration and electrodialysis as well as chromatography and ion-exchange processes.
In particular, we have specialized in…
• Biomass valorization: our processes purify cellulosic (C6) and hemicellulosic (C5) sugars, which are the raw materials for various fermentations and enzymatic / catalytic reactions enabling the production of bio-based molecules.
• Purification of biobased molecules (downstream processing, DSP): Eurodia’s technologies are used downstream of fermentation operations, raising the grade of bio-based molecules (organic acids, amino acids…) to the standards of secondary-processing industries (biobased and biodegradable plastics, alternatives to conventional plastics, green detergents and solvents, etc.).
• Production of organic acids: starting with various agricultural raw materials, Eurodia’s processes make it possible to obtain: the lactic acid used in the agro-food industry and in making biodegradable plastics (PLA); succinic acid (a platform molecule useful for developing other molecules and specialty composites: polymers, resins, etc.); acetic acid for various applications (biosolvents, preservatives, antiseptics…); gluconic acid, a chelating agent used particularly in biodetergents; and many others
