Considering the great generation of forest and agro-industrial waste produced respectively in the wood processing industries and crops of sugarcane crops of sugar and grains from the state southwest region as well as the fate of the waste generated in production processes, which generally They are used as biomass in power generation in sugar and alcohol mills, brick kilns in the production of ceramic products in farms as lining of bird waste, among other low value-added applications of these materials. The objective of the present work, study the characteristics and plant fibers properties and wood particles in the form of planing chips, from the development of vessel production techniques for use in gardening in order to obtain a product with physical characteristics and similar mechanical strength to the vessels of the tree fern as formerly produced with stem material of palm trees. During the development of the production process, for different grain sizes of the particles, the following materials were tested: wood chips species Imbuia and Pinus, sugarcane bagasse, coconut fibers and thatch. The adhesive used for sizing of the materials presented better match the type of mixture was the Polyvinyl Acetate (PVA) diluted in different proportions of water or used undiluted. The pots were placed in aluminum molds, then dried in electrical oven and demolded with different products (cellophane film, silicon, or carnauba wax and petrolatum base). The results were analyzed and discussed based on geometry, homogenization of the mixture, density, stiffness and proportional content of adhesive for each material tested
