These boards were manufactured using processes such as heat treatment, steam treatment, compression, and extrusion. Most of the targeted applications for these boards involve interior furniture and insulation board for building. This article briefly reviews the development of binderless boards from various natural fibres. It follows by presenting the manufacturing processing of binderless boards and the effects of section-manufacturing processing parameters on the properties of binderless boards. Then, the properties of binderless boards produced are described, and the last section mentions the current uses of binderless boards. DEVELOPMENT OF BINDERLESS BOARDS FROM VARIOUS NATURAL FIBRES Fundamental knowledge of natural fibres and binderless board properties will provide a broader view of the development of binderless boards with specific properties for specific applications. Natural fibres are normally lignocellulosic, mostly consisting of cellulose microfibrils in an amorphous matrix of lignin and hemicelluloses, together with other contents such as pectin, waxes, and fats (Joseph et al. 1999; Mohanty et al. 2000, 2005). Table 1 summarises the advantages and disadvantages of natural fibres. Table 2 shows the chemical composition of various types of natural fibres, as reported by several researchers.
Table 1. Advantages and Disadvantages of Natural Fibres (Sreekumar 2008) Per Table 2, researchers have studied various types of lignocellulosic waste material for fibreboard production. Among the natural fibres used in manufacturing binderless boards are kenaf, oil palm, coconut husk, banana bunches, and bagasse. These materials will be discussed briefly in this review. Waste materials such as durian peel, date palm, bamboo, paper, corrugated board, and agricultural waste also have a strong potential to be used as raw materials; however, further research is needed.
