Coconut coir

Coconut coir is the long fibre (15-35 cm) from the husk of the mature coconut and the average husk weighs 400 grams [7]. Coir is a fibre source for many cottage industries

Similarly, in the case of liquid fuel production, coconut shell, cotton gin waste, groundnut shell, coconut coir and rice husk show better properties. 

Coconut shell, groundnut shell, wood, coconut coir and rice husk are better suited candidates compared to the other biomass studied for pyrolytic gasification applications. 

U.S. Pat. No. 6,983,571 [73] discloses a composite roofing panel comprising polyethylene, polypropylene, or a combination thereof in an amount of 20-40% by weight, and natural plant fiber in an amount of 40-75%, selected from the group consisting of wood flour, sugarcane bagasse, hemp, coconut coir, jute, kenaf, sisal, flax, coir pith, rice hulls, and cotton.

Fibers are collected from the fruit of the plant, e.g. coconut (coir) fiber. Fibers are actually the stalks of the plant. For example, straws of wheat, rice, barley, and other crops including bamboo and grass. Tree wood is also such a fiber... 

Lai et al. evaluated the suitability of coconut coir fibers to prepare fiber composites prepared by compression method. The fibers were treated using alkali, stearic acid, etc. to improve the interfacial bonding between fiber and matrix. The composites based on chemically treated fibers exhibited superior mechanical properties compared with composites prepared using untreated fibers. Authors conclude that the superior properties are due to improved adhesion and enhanced polar interactions along the fiber-matrix interface [39].

The durian peel and coconut coir mixture was then used to develop low thermal conductivity particleboards. It was reported that the mixture ratio of durian peel and coconut coir was optimum at 10 90 by weight. In comparison with durian only particleboards and coconut only particleboards, the mixture particleboards showed better properties, except for the modulus of elasticity. The mixture particleboard is of lower thermal conductivity, which is suitable for ceiling and wall insulating materials. With more development, it will not be impossible to use this material for furniture applications. 

Coir fibers are obtained from the husk of the coconut. Coir fiber is generally extracted by mechanical means from the plant [52]. Manilal et al. [52] extracted coir fibers by a closed retting process in an aerobic retting reactor. Bakri and Eichhorn [53] mechanically extracted coir and celery fibers and studied their tensile behaviors in terms of micromechanics. Mothe and Miranda [45] studied the thermal stability and chemical constituent analyses of coir fibers. Khan and Alam [54] investigated the effects of several chemical treatments on the thermal and meachanical properties of coir fibers. Mahato et al. [55] studied the effect of alkalization on the thermal degradation of coir fibers. 

While others may exist, a choice was made to only discuss bagasse, cereal straw, coconut coir, corn stalks, cotton stalks, jute, kenaf and rice husks [3, 4].

Coconut coir is an invaluable gift of nature. This unique material has been used to make materials of our daily needs, household articles, handicrafts, and many others. Lignocellulosic natural fibres exhibit properties, such as biodegradability and recyclability, either by composting or by incineration, which are desirable to be considered as characteristics of sustainable materials.
