Impact Prerequisites Uses Cost Future outlook Contact Resources Supplemental information IntroductionThe commercialization of a technology once discarded as economically unviable is now generating jobs for rural women, saving thousands of hectares of trees, and boosting small-scale industry in India. All this from a modest investment in research.With the support of IDRC and the International Network for Bamboo and Rattan (INBAR), scientists at the Indian Plywood Industries Research and Training Institute (IPIRTI) have developed a cost-effective way of making plywood-like boards from bamboo mats woven by low income, rural women. The mats are coated with glue and hot-pressed to produce the mat boards, which can then be used to build houses, packing cases, storage bins and carts, among other things. This new industry has helped revive traditional mat weaving in tribal areas and raised women's incomes. Moreover, it has reduced the pressure on shrinking tropical forests by replacing wood with faster-growing bamboo, which regenerates in four to five years. The idea ofmaking bamboo mat boards (BMB) first arose in 1963, but it did not evolve commercially for a variety of reasons, including a sophisticated production process, high production costs, non-uniform bonding, and the unseemly appearance of the final productdueto the build-up of glue. From a development perspective, however, the technology promised to generate rural employment, enhance community development, and save depleted forest resources. This potential encouraged IDRC and INBAR to explore ways of making the technology commercially viable (see Supplemental information below) Impact
PrerequisitesEssential to successfully implementing this technology is a closely controlled production process including: uniform thickness of the bamboo slivers used to weave the mats; appropriate glue characteristics, moisture content, pressing parameters, and drying temperature of the resin-treated mats.UsesBamboo mat boards are currently being used in house construction (walls, doors, ceilings), transportation (roof and sides of carts), packing cases, storage bins, furniture and, more recently, in concrete form work. Other potential applications include constructing prefabricated houses for use during earthquakes, floods, and other natural disasters.Bamboo mat boards are an ideal substitute for thin plywood, which is expensive because prime quality logs are increasingly scarce and priced very high. CostThe cost of wood-based panels has been fluctuating recently due to a logging ban. Research is needed to compare the cost of bamboo mat boards to plywood made with phenolic glues.Future outlookBamboo mat board technology is gradually being adopted by the traditional plywood industry. It is expected that a large number of plywood manufacturers will eventually adopt the technology due to a recent decision by the Supreme Court of Indiathat bans many kinds of logging.IPIRTI is carrying out a number of research efforts aimed at refining BMB production and the final product. This includes efforts to: refine the glue and glue applicator; explore options for reducing the cost of glue; develop bamboo mat wood veneer suitable for structural uses; develop composition boards based on other plant or wood materials in combination with bamboo mats for various applications; determine, through amarket survey, the bamboo mat boardcharacteristics necessary for various applications. IDRC hopes to transfer this technology to the National Development Research Council (NDRC), an Indian government enterprise that has a broad scope for disseminating and commercializing thetechnology.

Understanding the characteristics of woven bamboo mat as compared to the wood veneer used in plywood production was a key factor in thisdevelopment. Research was also necessary to design an efficient glue applicator, reduce the amount of glue required to produce bamboo mat boards, and develop processing requirements that were similar to or simpler than those for bond plywood. Researchers also focussed on developing panels that are acceptable in appearance, waterproof, and resistant to decay and insect attack. |
