Palm Kernel Shell
Palm Kernel Shells (or PKS) are the shell fractions left after the nut has been removed in the palm oil mill. Its high calorific values (on the average 4000 Kcal/kg) and low content of ash and sulphur recently have made it an attractive renewable energy fuel.
Palm Kernel Shell can be burn as an independent eco fuel or, as a natural, high quality pellet, burn in cogeneration kettle as an addition to coal (in this form it significantly reduces the CO2 emission).
PKS can also be used as an addition to other biomass fuels.
The material offered by us originates from plantations in Malaysia and Indonesia. The oil palms bear fruit year-long, and production capacity of oil producers is so high, that it guarantees permanent access to the offered product and assures, that high quantity deliveries are imported to Poland regularly on a monthly basis by ships.

Advantages of using PKS as biomass
The features and characteristics of the offered product make it the best among the available biomass fuels. High repeatability of the fuel's parameters along with competitive price assure economy, low CO2 emmision and tax allowances, as well as lower costs of inner logistics and savings in exploitation of kettle's peripherals (such as loaders or transporters). There is also no need to invest in such expenses as canopied storage yards.
- high calorific value 14-20 000 kJ/kg,
- very low ash content about 2%,
- stable moisture content 10-20%,
- resistance for crushing also in long-lasting shipping,
- constant granulation curve,
- constant granulation (similar to II A coal dust),
- advantageous apparent density – possibility to use also in bottom-blowing hearths,
- inexpensive inner logistics (thanks to high callorific value),
- resistance for atmospheric conditions - no need to store inside,
- possibility of regular deliveries,
- blends well with coal dust,
- far more resistant to rotting than wood.
The above table of calorific value, moisture and absorptivity of the analyzed samples of Palm Kernel Shel and woodchips (taken from outdoor storage yards) illustrates the huge predominance of the offered product above traditionally used woodchips.
