Due to the lack of application of new technologies in the municipality of Ocaña on energy inputs such as biomass, a great amount of material such as sawdust is being wasted, which could be used for energy consumption, such as the replacement of firewood that is in great demand in rural areas for food preparation. The purpose of this research is the identification of the main sources of biomass production, the performing of moisture and ash tests to observe if they have the properties required for biomass production from the different types of sawdust in the laboratory of Francisco de Paula Santander University Ocaña. The type of research used in the project is experimental research. Thanks to the characterization study of sawdust residues in the furniture factories of the municipality of Ocaña for energy production, some characteristics are obtained of the properties of ash and moisture of the types of wood that are used in the zone, which were Oak, Colombian mahogany, wild cashew, Higuerón, cedar and sapan (Clathrotropis brunnea Amshoff) that can be usable fuels in the future for furnaces or boilers.
