Coconut Fiberboard is a novel and innovative product made up of cement, coir, shredded wood, fronds and other ligno-cellulosic materials that are available in coconut farms which are otherwise considered as agricultural waste (CFB). It is a new product manufactured from fibrous materials like coconut coir, fronds, spathes and shredded wood that are mixed with Portland cement at a predetermined ratio of 70% cement to 30% fiber by weight. CFB is made by forming the cement-fiber mixture into mats and pressing them to the desired thickness ranging from 8 mm to 25 mm. The board is 244 cm long by 61 cm wide.
CFB can provide panels of good strength properties. It is considered cheap, durable and requires low maintenance cost. The production technology is simple and the manufacturing process requires equipment that do not need highly skilled labor. It can be fabricated into modular structures to accelerate building construction. It is a good insulating material and has fire retardant characteristics. It is water resistant. It is also nailable, plasterable, sawable and resistant against attack of wood-boring insects and decay fungi.

Advantages of Coconut Fiberboard
- A good and environmentally-friendly alternative to plywood.
- Easy to install.
- Low cost (P 120 / 2″ x 8″ board).
- Fire resistant.
- Termite resistant.
The production of CFB involves the following steps:
First is soaking of dried husk/spathe in tap water for 24 to 48 hours.
- Extraction of coir through decorticating machine.
- Shredding woody materials (fronds and small-diameter fast-growing trees planted along the borders of coconut plantations).
- Soaking of shredded woody materials.
- Weighing of desired coir and shredded woody materials.
- Mixing of cement, coir & shredded woody materials.
- Mat-forming using wooden form box and plywood cauls lined with plastic sheets.
- Pressing the mat to the desired thickness for 24 hours using the hydraulic press machine.
- Trimming/sizing of the boards.
- Drying and conditioning of the boards.

The major equipment/machinery used in the manufacture of CFB are all fabricated locally except the lifter
and include the following:
- Decorticating machine
- Hydraulic press
- Blending machine
- Trimming machine
Uses of CFB
Production of CFB is expected to contribute to the government’s low-cost housing program. CFB can replace traditional construction materials such as tiles, bricks, plywood, asbestos and cement hollow blocks. It can be used for internal and exterior walls, partitions and ceiling or as a component in the fabrication of furniture (tables, chairs, desks, etc.), cabinets, boxes and vases.
