The Assessment of the Bioenergy Potential of Forest Biomass in the Provinces of Cuanza Norte and Malanje in Angola

Abstract

The high dependence on hydrocarbons in the global energy matrix, particularly in Angola, has

caused serious environmental impacts, mainly due to the increase in greenhouse gas emissions. In this

context, it is necessary to diversify the national energy matrix through the incorporation of renewable

sources, highlighting forest biomass as a strategic alternative for the production of biofuels, such as bio-

oil, bioethanol, and Sustainable Aviation Fuel (SAF). This study aimed to characterize forest biomass

and evaluate its bioenergy potential in the provinces of Cuanza-Norte and Malanje, encompassing the

municipalities of Cambambe, Lucala, Ambaca, Cacuso, Cangandala, and Kiwaba Nzoji. The

methodology integrated field surveys, dendrometric analyses, forest sampling, laboratory procedures,

and the use of Geographic Information Systems (GIS). The results demonstrated the existence of forest

formations with high energy potential, although some plant types present high moisture and ash content,

requiring complementary drying and pre-treatment processes. Species such as Trichilia dregeana,

Combretum molle, and Jatropha curcas stood out, with significant potential for the production of

biodiesel, charcoal, and solid biomass. Despite spatial and laboratory limitations, the results obtained

confirm the technical viability of using forest biomass as a sustainable alternative for energy

diversification in Angola.
