Coffea arabica L. var. Cenicafé 1, developed by the National Coffee Research Center of Colombia (Cenicafé), offers improved productivity, quality, and disease resistance, but its processing generates coffee husk, a by-product often considered waste. This study explores the thermo-chemical properties of the husk from this new variety to assess its potential for biofuel production. By utilizing this husk, waste management challenges were addressed while providing a sustainable energy source. Key properties measured include calorific value, ash content, elemental composition, and ash behavior. The calorific value was found to be 18.55 MJ kg-1, higher than many other coffee husks, suggesting strong energy potential. The ash content was notably low at 0.83%, and the minimal presence of nitrogen, sulfur, and chlorine reduces the risk of harmful emissions during combustion. The ash composition also indicates that it can be safely used as fertilizer, promoting a circular economy. Overall, the husk from Cenicafé 1 displays characteristics comparable to wood but with even lower ash content, making it an ideal candidate for biofuel. This study underscores the dual benefits of improving waste management and generating renewable energy from coffee husks, contributing to sustainable agricultural practices.
