Palm Kernel Shell (PKS) is a renewable biofuel made up of the hard shells of palm kernel nut.

In the palm oil milling process, palm kernel nuts are separated from the fibruos palm pulp. The nuts are then cracked to extract the kernels for subsequent oil extraction while the shells are separated from the main processing line. Part of the shells are used as fuel for the boiler and the balance is processed into renewable palm biofuel.

Similar to other nut shell, PKS has calorific value close to that of wood pellets, lignite (brown coal) and peat, with Lower Heating Value of 3’500 kCal/kg and Higher Heating Value of 4’000 kCal/kg.

Moisture content is kept below 20% to enable dependable boiler and burner emission and combustion performance.

In addition to improving carbon footprint, some of our clients are truly enjoying the benefit of fuel cost reduction. The following table shows the actual fuel expenses incurred by the existing diesel fired production lines (C2 and C4) and biomass fired production line in 2014. The cost analysis concludes that there is a 47% cost reduction switching over from diesel to biomass.  

We recognize the importance of uninterrupted fuel supply. Hence, we are committed to set up biofuel logistic network and storage facility nearby your facility. Please contact us for detailed logistic arrangement that delivers you the renewable biofuel at lowest possible carbon footprint.

PKS-Fired Dryer for PKS Drying 

PKS fuel is dried and screened for emission and clinker control.

The drying process is powered by PKS itself, hence, low in overall carbon footprint
