Decomposed PKS can be obtained from palm oil mill dumped area. This waste consist unburn palm kernel shells, fibers, boiler ash, and miscellaneous particulate matter that mainly come from steam boiler. 20% of this waste consist decomposed PKS. It has been there for over 15 years ago.
We have seen this opportunity as an alternative way to an increasing price of fresh PKS in the market. We bought this waste and filter them gradually to separate the the reamining PKS from the other waste. The result was not so clean but could be improved by means of cleaning and drying. The calorific value is still high at around 3500 Kcal/kg (Dried basis)
