Coffee oil
Obtained by defatting spent coffee grounds.
03 Cosmetic Ingredients
From spent coffeeto cosmetic ingredients
Defatting spent grounds yields coffee oil and polyphenols, supplied as cosmetic ingredients for early revenue.
01Ingredients
Two ingredientsfrom defatting
Polyphenols
Extracted in the same pre-treatment step.
02Test Results
Antioxidants in,no microbes or heavy metals
An external lab tested a research sample extracted from spent coffee grounds with anhydrous ethanol.*
- Total polyphenols
- 4,735~5,143mg GAE/kg
- Total flavonoids
- 4,342~4,866mg CE/kg
- Total antioxidant capacity
- 4,853~5,627mg AAE/kg
- Microbes
- Not detected
- Heavy metals
- Not detected
* Thermophene internal reference data. Values for a single research sample from external labs' reference-only reports; they do not guarantee product specifications or efficacy. Antioxidants analyzed by NICEM, Seoul National University, in October 2026 (mean of three runs, range across two extraction conditions); microbe and heavy metal tests from September 2026.
03How It Is Made
From raw material to TIM,nothing is wasted
Coffee oil comes from the second step of the platform. The remaining grounds become porous carbon and thermal materials.
-
STEP 1Raw material
Spent coffee grounds
200,000 tons wasted in Korea every year, with ~40% carbon yield.
-
STEP 2Defatting
Coffee oil
Sold as a cosmetic ingredient for early cash flow.
-
STEP 3Activation
Porous carbon
Sold as deodorizer feedstock. Zero loss.
-
STEP 4Core R&D
Thermal interface material
Cu-C filler with 12 W/mK, our main revenue.
- Efficiency: raw material reuse
- 100%
- Performance: revenue streams
- 3streams
- Value: coffee grounds supply (Jeonbuk, monthly)
- 1,000t
04Partnership
MOU signed with a cosmetic ingredient company in April 2026.
We also received a letter of intent. Coffee oil sales create cash flow from the early stage.
