Wastes from wood agro-forest materials (coconut shell, coconut husk, coffee bean hull, sawdust and others) can be turned into usable products such as charcoal briquettes.

Charcoal briquettes are compacted charcoal powder mixed with starch and molded under pressure. They are more efficient to use than ordinary charcoal since they are more solid, easier to transport, and burn longer and more steadily. They are ideal for bakery, restaurant and poultry farm use.

FPRDI’s briquetting system consists of the briquettor, mixer and dryer. It comes with a continuous rotary carbonizer that converts agro-forestry wastes into charred powder, which is then made into briquettes.

FPRDI has also designed a froth flotation cell that improves briquette quality by cleaning the charcoal powder before this is made into briquettes. Charcoal powder coming from granulating plants has lower heating value than lump coco shell charcoal because it carries a lot of impurities.

Advantages

  • Uses waste charcoal powder produced by granulating plants
  • Can be a substitute fuel to liquefied petroleum gas, kerosene and electricity
  • Less messy and easier to handle than ordinary charcoal because they are compact and uniform in size
  • Easy to ignite, slow-burning, emits more intense heat per unit volume and almost smokeless when burning
  • Can substitute for coal or coke in steel processing and in calcium carbide plants
  • Minimizes wood charcoaling, thus relieving pressure off the forest resources
  • Potential export material due to heavy demand in the US, Japan, Korea and Malaysia
  • Can generate employment especially in the rural areas
