What is Palm Kernel Shell (PKS)?
Palm Kernel Shell (PKS) is a hard shell left after extracting palm kernel oil from oil palm fruits. Instead of being treated as agricultural waste, PKS is processed into an environmentally friendly biomass fuel with high energy efficiency.
Due to its excellent combustion characteristics, PKS is widely used as an alternative to coal in industries seeking to reduce carbon emissions while maintaining stable energy production. Learn more about our range of sustainable biomass products.
