Resumen : The global tradition of building is severely affected by the shortage of materials from nature, which stimulates the development of technologies and construction systems related to the reuse of waste organic. For example, in Ecuador an area of 106,930 ha in 2012 was devoted to sugar cane plantations, having a production of 7.38 Mt (7.5% in the province of Loja), which produce the organic residue sugarcane bagasse, mainly in mills owned by artisan manufacturers. Approximately 50% is used as fuel, fertilizer and livestock feed, the rest as waste accumulates in particular landfills with health problems. Recovery and use of this residue as a component of craft supplies of building materials is proposed in this communication. The design of composite materials containing organic vegetable wastes is proposed, and the measures of their physical and mechanical properties are described, pointing to elements that combine technical, specification standards and artisan production that will generate a production for low cost housing in the area of the province of Loja.This work is part of an ongoing investigation, conducted in collaboration by professors and researchers from the Universidad Técnica Particular de Loja (Ecuador) and the Technical University of Madrid (Spain), divided into two phases: the first an analysis is made in laboratory of some organic vegetable waste from the province of Loja; in the second part and simultaneously, are proposed and built prototypes of architectural elements, that incorporates the materials investigated. In the first stage results have been obtained of the mechanical and physical properties of composites with bagasse, in matrices made of plaster and cement, with additions of ashes of those vegetable waste materials, as well as impact on measures absorption and capillarity of these composite samples, confirming the effective delivery of materials with potential applications in building construction. In the second stage it was accomplished the manufacturing and constructive use of plates and sandwich panels at scale 1:1, determining dimensions, combining different elements, modulation, anchoring systems and their mechanical resistance, obtaining materials with acceptable values on toughness. There were explored various treatments to materials (organic fibers and matrices) for improving protection against external environmental agents. It was concluded that the composites made from vegetable organic additions of bagasse, with and without ashes from the same waste materials, in plaster and cement matrices allow reusing waste materials that are sustainable and provide eco-efficient execution of architectural projects solutions.
