During the processing of the olive kernel, two main products derive.

Crude kernel olive oil (pomace oil)

After the picking, olives are taken to the oil mill where most of the olive oil is extracted. What remains -a pulp of skin and pit “wood”- is called olive oil kernel and is the raw material for the functioning of the kernel olive oil factory. Within the kernel, there is still enough oil (roughly ~4%) and humidity (~50%). Once in the factory, the kernel is dried up so that most of its humidity is removed. Then, comes the procedure of extraction with hexane; the kernel’s remaining oil can now be isolated: this is the crude kernel olive oil.


The crude kernel olive oil has a dark brown-green hue and is sold to refineries in Greece or abroad. There, after being re-processed, is made available in the market as refined olive oil (pomace oil). It is a cooking oil of great quality, suitable for eating, raw or cooked.

Olive pit biomass

After drying the olive pulp and extracting the oil, what remains is only dried up olive kernel.

The kernel consists of:

a) the olive kernel which is woody and fragmented

b) the olive’s flesh – dried up, in powder

c) the fruit’s skin, also in powder.

Olive pit biomass

Pomace wood is then used as biofuel for energy production. It is a 100% natural and economical fuel compared to petrol. In addition, it is ecological with high caloric value and considerably cheaper than other fuels since it is a local product produced by olives.

Only specially-designed biomass burners can be fueled with olive pit. Pomace wood can be used for central heating in households, steam or energy production (businesses such as bakeries, laundries, distilleries and more).

PIRINELEOURGIO ALBANTAKI IERAPETRAS LTD produces high quality pomace wood, with low humidity. It is available for wholesale or retail, in sacks or pallets.
