Presentation at the Formulation Days, 29 November - 1 December 2021
The 20th edition of the Formulation Days of the French Chemical Society took place from November 29 to December 1, 2021 on the UTC campus in Compiègne. The event is co-organised by the TIMR Unit (UTC-ESCOM), the GRD Cosm'actifs of the CNRS, and the Formulation Group of the SCF, in partnership with the SFR Condorcet and the Pôle IAR.
The theme of this year's event is "Substitution and Reformulation: today's challenges, tomorrow's products".
The programme of these days includes oral conferences, exhibiting partners' stands, start-up demonstration stands and poster sessions.
" Biobased products for chemistry and materials are non-food industrial products obtained from renewable raw materials from biomass. By substituting the fossil raw materials used, the Green chemistry By substituting the fossil raw materials used, the Life CycleAssessment (LCA) method contributes to reducing dependence on fossil resources and improving the environmental footprint of products and processes, according to different categories of environmental impacts, in particular climate change.
By proposing a multi-criteria environmental assessment over the entire life cycle of the product system, theLife Cycle Assessment (LCA ) method represents today one of the most successful tools to support manufacturers in theeco-design of their bio-based products.
The use of biobased materials for industry is associated with specific environmental aspects that can be integrated into the LCA assessment, in particular the storage of biogenic carbon in biomass. However, the method faces certain methodological obstacles, particularly when it comes to making a comparison with generic petroleum-based references, derived from more mature and optimised processes.
ITERG's Environment & Eco-Industries Unit assists industrial producers of biobased materials or molecules in the environmental assessment and ecodesign of their products in order to improve the environmental performance of production and R&D (agricultural and industrial phases), to meet the expectations of their customers committed to a sustainable supply approach, to compare biobased products with petroleum-based products, etc.
" We stabilized emulsions using oleaginous press cake powders only. Several impacts are discussed: powders composition, emulsification process, nature of the oil phase, powder content and aqueous/oil ratio. The resulting emulsions are very stable and many textures can be reached, from fluid to gel. Emulsions can also be dried to obtain a non-sticky powder rich in oil and redispersible, which can be advantageous for emulsion transport, formulation, microbiological stability and encapsulation of lipophilic compound. We also find that the lipid oxidation is significantly delayed when linseed oil is emulsified with rapeseed press cake, in aqueous and dried emulsions.
