    The availability of agricultural waste for bioenergy generation come to propose the recent interest by agroenergy sector. For this goal, this dissertation show a bibliografic study for waste characterization of cocoa bark, coconut bark and coffee bark in according to bioenergy technologies: anaerobic digestion, pyrolisys and direct combustion. Its made analysis of technology route possibilities for transform the energy potencial from fruit waste composition in electric energy. The objective its towards the structural synthesis of chemical process by problem representation with process state trees. From the combination of elements of study: fruit waste, biomass processing technology and chemical conversion technologies; its proposed the possibilities of technology routes for elaborate the branches of state trees. The step of structural optimization its based in applied the heuristics method towards the syntesys problem. Thus, its selected the most promised technology route of energetic use of each waste. As a result, the anaerobic digestion in batch reactor was the better option for cocoa bark. For a coconut bark, the chemistry route more adequated was the direct combustion, realized in boiled fixed grid; and for a coffee bark, the thermochemical pyrolysis conversion preceded by pelletization compactation showed more promised. As contribution from this work of dissertation stands out the possibility of energetic valorization of fruit waste untill then considered useless for energetic sector. The problem representation by systematic of state trees and after applied solution by heuristics rules show the originality from this proposed work.
