Initiatives that stimulate the use of renewable resources to replace fossil sources in pursuit of the energy transition gain visibility in the context of global warming, the main planetary environmental challenge. In the study, a comprehensive technical approach was applied to evaluate the energy potential of Giant reed (Arundo donax L.), a herbaceous plant of Asian origin, considered a species of good biomass yield per hectare. From randomized block designs and standardized techniques, agronomic trials were carried out in the SE of the Province of Buenos Aires, obtaining yields between 5 and 11 t/ha, higher at higher planting density. The technological characteristics of the biomass showed an average cellulose content of 53 % and a higher calorific value between 4000 and 4500 kcal/kg, confirming its potential as an energy crop. The results on the production and use of the biomass demonstrated the availability of technological capacities for its exploitation without impacting soils and taking advantage of its potential as a renewable energy resource. Thus, we reflect on the value chain of the species that allows promoting localization processes of projects that activate complementarities between singular territories.
