On 12.11.2021 the implementation of project BG16RFOP002-2.089-5250-C01 "Support for small enterprises with a turnover of over BGN 500,000 to overcome the economic consequences of the COVID-19 pandemic" started. The grant amounts to BGN 50,000, of which BGN 42,500 is European funding and BGN 7,500 is national. The aim of the project is to provide operating capital for the company "Comerg Group", through which we will be able to more easily overcome the shortage of funds that occurred as a result of reduced revenues as a result of COVID-19. The project will last 3 months. The results we will achieve are related to the improvement of our liquidity and the provision of additional funds with which to continue to carry out our core business.


On September 29, 2020, started implementation of project BG16RFOP002-2.073-24889-C01 titled "Overcoming the lack of funds and the lack of liquidity, which occurred as a result of the epidemic outbreak of COVID-19". The grant amount received is BGN 10,000, of which BGN 8,500 is European and 1,500 is national co-financing. The aim of the project is to provide operating capital for "Comerg Group" Ltd., to be able to easily overcome the restrictions that occurred as a result of reduced revenues from COVID-19. The project will last for 3 months. The results are related to the improvement of liquidity and provision of additional funds to continue to carry out the core business.

COMERG to Unveil and Demo New Natural Extraction Technology at Natural Products Expo West at Booth H538

Faster, Cheaper, and Higher Yield than its Carbon Dioxide Competitors

The new Low Pressure Extraction (LPE) technology, which COMERG calls Atomic, is not only significantly safer, but produces a higher yield, is faster to produce, and is less expensive than current carbon dioxide extraction machines. "Our new Low Pressure Extraction technology is a game-changer for the food, pharmacy and perfume industries because it can produce up to six times higher yield than the CO2 technology in one- sixth of the time, while process cost is only one-sixth of the cost of CO2 process," COMERG CEO Dr. George Stantchev said: "We're excited to introduce LPE and COMERG's Atomic at the Natural Products Expo West and invite everyone to visit our booth to see what we offer, both in regards to processing equipment and the naturals themselves." Atomic process combines two separate carbon dioxide processes into one while creating a significantly greater yield in a fraction of the time (for example a 3--50-minute cycle versus 300-minute cycle for a standard carbon dioxide process). Unlike the existing carbon dioxide industrial size machines, COMERG's Atomic LPE technology is also only a fraction of the cost.

How does LPE work?

Low Pressure Extraction combines novel extraction methods based on tetrafluoroethane (TFE). TFE has long been overlooked to extract a wide range of compounds since the industry adopted carbon dioxide and other methods. TFEs has very low boiling point and separates completely from the most volatile components of the extract, therefore leaves no residue in the end product. The extracts can be produced with high purity and on a large scale under extremely low cost. Since the critical pressures and temperatures are much lower than carbon dioxide, construction the LPE apparatus are significantly reducing CapEx and OpEx.

Additional facts about COMERG's Atomic LPE Technology:

  • Down to 20% CapEx of carbon dioxide extractor from energy and cost
  • Higher yields on shorter run times with cleaner product results
  • Higher solubility of output for use in food, drinks and medicine
  • Able to handle fragile natural ingredients with less degradation
  • Low Maintenance due better design and construction
  • Fraction of energy needed during processing
  • With no solvent residue in the final product
  • Fire Safe due to GRAS (generally recognized as safe) solvent
  • Low Pressure and high safety technology
  • Low Temperature liquefied gas extraction
  • Full solvent recovery with no production losses
  • Allows extraction of fresh and even moisturized product
  • Unique extraction method that keeps full flavor and aroma
  • Preserves the full nutritional significance of the ingredients
