Palm Kernel Shells (PKS)

Palm Kernel Shells (PKS) are the hard outer shells of the palm kernel fruits that are left as a by-product after the extraction of palm oil. PKS is a high-density material that is rich in carbon and can be used in various applications such as fuel for biomass boilers, charcoal production, and as a raw material for the production of activated carbon.

Using palm kernel shells to cofire with other solid fuels such as wood chips and coal has been successful thanks to their uniform size distribution, scalability, easy handling and applicability with existing logistic set ups.

Our approach

Responsibility starts at the source

For every biomass product in our portfolio, we take responsibility for understanding where it comes from and how it moves through the supply chain. That is why our approach is built on responsible sourcing, documentation and transparency.

  • Origin

    The origin of PKS is South East Asian and West African countries. Indonesia and Malaysia are major sources of PKS for biomass, with the countries’ ample palm oil industry producing significant quantities of this biomass residue. These countries are closely followed by Ivory Coast and Ghana which are also large producer of palm kernel shells.

  • Availability

    The scalability of PKS for biomass is one of the products key advantages, as the palm oil production only in Indonesia and Malaysia generates around 6.5 million metric tons of PKS annually.
