Presentation at the Formulation Days, 29 November - 1 December 2021
The 20th edition of the Journées de Formulation de la Société Chimique de France will take place from 29 November to 1 December 2021 on the UTC campus in Compiègne. The event is co-organised by
. 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.
"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.
