Palm Kernel ShellsThe Palm Oil Plant (Elais Guinensis), considering its three different varieties Durà, Pesipherà and Tenerà, produces an edible fruit similar to an apricot which has inside a nut. During the crude palm oil process the fruit’s flesh is melted through a steaming treatment. The residual nuts are further mechanically crashed to extract the seeds or Kernels. The crashed shells are called Palm Kernel Shells (PKS), a virgin biomass with a high calorific value (NCVAR typical abt 3,800 Kcal/kg – ASTM D5865 – 02).
Palm Kernel Shells has a very low ash and sulphur contents:
- » Ash content (typical abt 3% weight – ASTM D3174-02)
- » Sulphur content (typical abt 0,09% weight – ASTM D4239 – 02)
