As the world shifts towards renewable energy, biomass fuels are gaining attention as a sustainable alternative to fossil fuels. Palm kernel shell (PKS) — a by-product of palm oil production — has emerged as one of the most efficient and widely available biomass fuels, especially in Malaysia, the world's second-largest palm oil producer.
What Is Palm Kernel Shell?
Palm kernel shell is the hard, dark brown shell that remains after the palm kernel is extracted from the palm fruit. Each palm fruit produces a small amount of shell, but given the massive scale of Malaysia's palm oil industry, millions of tonnes of PKS are generated annually. Rather than being discarded, this material is now a valuable energy source.
Why PKS as Fuel?
- High calorific value: PKS has a calorific value of 3,800-4,200 kcal/kg, comparable to low-grade coal but with far lower emissions.
- Low moisture content: At 10-15% moisture, PKS burns efficiently without extensive drying.
- Carbon neutral: Since palm trees absorb CO2 while growing, burning PKS is considered carbon neutral in the lifecycle.
- Abundant supply: Malaysia produces over 4 million tonnes of PKS annually.
- Low ash content: PKS produces only 1-3% ash when burned, reducing waste disposal needs.
Applications
PKS is used across various industries:
- Power generation: Biomass power plants use PKS as primary or co-firing fuel alongside coal.
- Cement kilns: Cement manufacturers use PKS to replace coal in their kilns, reducing carbon footprint.
- Industrial boilers: Factories use PKS in boilers for steam generation and heating.
- Export fuel: Japan, South Korea, and European countries import Malaysian PKS for their renewable energy programs.
PKS vs Other Biomass Fuels
Compared to other biomass options like wood chips or rice husks, PKS offers several advantages. Its uniform size (5-20mm) makes it easy to handle and feed into boilers. It stores well without degradation, and its high density means lower transportation costs per unit of energy.
Quality Standards
Quality PKS should have consistent size, low moisture content (below 15%), and minimal foreign matter. At S&S Coco Trading, we source PKS directly from palm oil mills in Malaysia, ensuring fresh, clean material that meets industrial specifications.
