The Production Process

• Wood waste often in form of sawdust is collected from sawmills, sifts and suitably sized waste will be collected as the sole raw material for the production.
• The wood waste is then going through the drying process either a rotary or jet system incorporated to a hot air generator, fueled by fine wood dust or timber waste.
• The dry raw material is then channeled to a compressing equipment known as screw extruder or forming machine while it is still in a hot/warm state, to produce the sawdust briquette under a screw pressure of approximately 40 tons through a hot (approx 300~ 350 Deg C ) mold. The pressure and the thermal energy force the Lignin(resin)to bind the wood waste under a high pressure to form sawdust briquette with density much higher than the wood origin.
• The briquette is then bundled ready for carbonization or Charring process. Charring requires 3-5days in the specially designed kiln. Cooling is either within the kiln itself (as for all conventional kiln) or removed for external cooling using cooling chamber/box (for rail-car charring system).
• The charcoal is then ready for packing according to the grading.
