Ply Board is wooden made board or wooden like raw materials largely used for making ply board. There is large use of ply board nowadays in making wooden base furniture. Bamboo can be used for making ply board. There is large amount of bamboo available in our country. Bamboo on special processing can be converted into ply board. Matured bamboos are used for making ply board. There is very good rising demand of ply board. For meet up the demand of ply board few new entrepreneurs can start this industry. In this process solid waste may be come up which can be recycled or can be further processed for making organic fertilizer. Bamboo Board The increasing shortfall of wood is giving rise to the development of non-wood materials. The development of bamboo-board is expected to relieve the pressure on wood, as the raw material is available at a much faster rate. Bamboo is harvested in a four to five year cycle against 40 years for medium density hardwood species used for plywood. The first bamboo-based panel was developed in China in the 1940s. Since then, some 28 panel products have been developed. In spite of this, the commercialization of bamboo panels has not been commensurate with the variety of products developed, mainly because only a few technologies have come out of detailed investigations and industry-scale trials. In the search for non-timber forest products to substitute wood, bamboo has emerged as a material par excellence. It is now widely recognized that bamboo in panel form is ideal to replace wood in several applications. It is in great demand in designer homes as flooring, walling, and paneling material. Based on the culm derivatives used, the boards may be grouped in the following categories : Culms converted into slivers, strips or lathes by flattening and/or cutting, and further processed, Culms peeled into veneers and further processed, Culms converted into particles, fibers, wafers or strands and reconstituted, Combination of one or more of above products among themselves or with other materials and further processed. Such composits include: different bamboo panels; wood or other lignocellulosic materials; and inorganic substances, Various types of bamboo boards are made from Bambusa bambos, B. polymorpha and Dendrocalamus strictus. Building-Board - There is a great demand for panel materials of all kinds in the building and furniture industry. Chemically processed bamboo strips or veneers are interwoven into mats. They are pressed together at high temperature to form boards properties of larger sizes of different properties with uniformity of strength in the principal directions. Flattening and widening of bamboo can also make boards. The processes involved in manufacture of building boards include defibering, thermal hydrolysis, mixing shavings with resin and finally pressing of resin treated bamboo mats. These boards have a pleasing appearance and adequate strength and optimum hygroscopicity. Boards from slivers, strips or lathes - Slivers of uniform thickness and width are woven into mats, following traditional or innovative designs and cold or hot pressed into boards. Particleboard - In India only a small quantity of bamboo particleboard (about 1500 tonnes/year) is produced. As a common national standard exists for particleboard produced from all lignocellulosic materials, bamboo particleboard requires to conform to IS : 30871985 (Standard Specification for Medium Density Wood Particle board for General Purposes). Bamboo strip, wood veneer and particleboard - Bamboo strip board forms the face. Wood veneer and particleboard are used as core. Bamboo mat boards - Bamboo mat board is the first bamboo-based panel to be produced commercially. Its versatility has been widely recognized. It is commercially produced in China (under the name bamboo mat plywood), India, Thailand and Vietnam. One of the major uses of bamboo mat boards is in building interiors and construction. Because of its aesthetic appearance the board finds ready acceptance as paneling material in place of decorative plywood or other pre-laminated panel materials. Boards being phenol bonded are very durable as compared to commercial panel materials. A factory in Kerala State started manufacturing Bamboo mat board in 1984 using the modified technology. This factory is still producing bamboo mat board, with slight modifications of the process, and marketing it for use in furniture, housing and shuttering. Bamboo mat and rice husk board - Bamboo mat is used as face and rice husk particleboard as core. It is produced in small sector industry in India. Stringer type board - In addition to flat ones, some mats are made in the form of bamboo tubes or the required size and treated with phenolic resin. Rectangular split steel mandrels are driven into these and are placed between two sets of flat mats in a continuous raw and pressed in a mould with side pressure. The bamboo boards can also be faced with fancy veneers or metals when covered with special type of wood shavings or bamboo shavings which can be dyed, they make attractive material for application in housing, decking, flush doors etc. Bamboo boards buried in test yards for more than eleven years were found to be unaffected by termites and fungi. Their resistance to fire is also similar to that of wood.
