Drying - water extraction

CO2 drying is a unique form of extraction, focuses on removing water from a substrate

Current drying methods like spray dryers, ovens, or sunlight are energy intensive and/or time consuming.

Overcoming challenges:

  • Careful substance selection and parameter optimization
  • Consideration of material properties
  • Development of tailored techniques or technologies

Competitive advantages

CO2 above a certain temperature and pressure (*)

offers the advantages of both a gas and a liquid:


  • Zero waste, no residue, no solvent. Nontoxic


  • Low T° (32°C): heat-sensitive products
  • (currently solvent often T° > 60°C)
  • Minimizes risk of thermal/chemical degradation
  • Penetrating power (density of a liquid, diffusivity of a gas)
  • Better unimodal size/population distribution
  • Obtain precise control over encapsulation
  • Avoids formation of unwanted by-products
  • Better control of product properties (encapsulation)
  • Biocidal properties of CO2 (sterilization)
  • More homogeneous and optimal properties (APIs) 
  • Enhancing product stability and bioavailability
  • Particle size >60 nm (vs microfluidique > 5000 nm)


  • Faster and compact process (no need separation steps)
  • Reduced process time (5 to 10 times)
  • Reduced operation cost (from to 2 to 4 times)
  • Compact, modular and integrated process
