Need for Clean and sustainable processes

  • Current processes require organic solvents
  • Require removal residual solvents for pure extract
  • High Temperature can be required (above 50°C)

Algae valorization: lack of cost-effective extraction methods

  • Algae is a promising, sustainable and abundant resource
  • Need a costly energy intensive, time-consuming drying step
  • No available continuous process

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)
  • Penetrating power (density of a liquid, diffusivity of a gas)
  • Highly selective product extraction
  • Minimizes risk of thermal/chemical degradation
  • Avoids formation of unwanted by-products
  • Better control of product properties (encapsulation)
  • Biocidal properties of CO2 (sterilization)


  • Reduced process time 30 min to 1 hour (5 to 10 times)
  • Reduced operation cost (from to 2 to 4 times)
  • Compact, modular and integrated process

How does it work ?

Extraction: CO2 extraction relies on the solubility of targeted compounds, like natural pigments, which is influenced by factors such as solvent density and temperature. Solubility curves follow an exponential pattern with density at a given temperature, affecting the extract's purity. The extraction time is determined not only by compound concentration but also by their attachment to the raw material. For example, extracting oils from algae like nannochloropsis proves challenging due to the impermeable membrane rather than oil solubility.

Fractionation: Supercritical fractionation is a process that separates compounds from liquids using a packed column and counter current flow. It is suitable for temperature-sensitive compounds and offers enhanced purity compared to short path distillation. Engineers optimize parameters like carbon dioxide flow, equipment volume, and pressure for cost efficiency. This method finds applications in polymers, fatty acid separation, squalene separation, purification of compounds from botanical extracts, and trace removal.

    Reduce OPEX & CAPEX

    Optimizing Engineering Techniques for Cost-effective Results

    Our engineering techniques prioritize minimizing pressure, process volume, flow, and time in CO2 extraction to reduce operational (OPEX) and capital expenditures (CAPEX). However, it is crucial to balance these parameters with product yield and quality. The combination of product quality, yield, and costs determines the economic viability of our extraction process.
