Cocoa (Theobroma cacao L.) Husk Potential for Biogas and Biofertilizer Production

Resumo

In the context of the transition to renewable energy sources, the valorization of agro-industrial waste is fundamental. Cocoa husk, in particular, emerges as a promising biomass, whose utilization can mitigate environmental impacts and foster a circular economy. The objective of this work is, therefore, to evaluate the potential of cocoa husk for the generation of biogas and biofertilizers. Despite technical challenges, such as its high moisture content, the conversion of this residue into energy can contribute significantly to the diversification of the national energy matrix. The research was conducted based on physicochemical analyses of samples collected in the municipality of Presidente Tancredo Neves - BA, covering parameters such as the determination of moisture content, total solids, volatile solids, ash, pH, cellulose, lignin, and heating value. This study contributes to the implementation of sustainable solutions and highlights the relevance of waste valorization in the transition to a clean energy matrix.
