Palm kernel shell (PKS) in it’s raw; unprocessed form is readily applicable to boilers and furnaces. However, natural state, raw palm kernel shells contain high moisture and high level of unwanted contaminants such as germs, fungus, bacteria, diseases, insects, sludge, ammonia and etc., all resulting in bad odours, unclean emissions, and ultimately, low calorific values.
We process the PKS to remove all contaminants. We then lower moisture levels to between 8% and 10%, depending on customer requirement. Next, we rotary dry roast the PKS to further kill any remaining bacteria. Our processing enhances the PKS burning qualities and cleans the biomass material to offer combustion that releases only clean, safe and aromatic emissions.
