Biogas and biomethane production
Advancing a Caribbean Circular Bioeconomy through Castor Seed Residue Biomethane Production and Digestate-Supported Cassava Cultivation
Short Introductive summary
This contribution presents an unpublished Caribbean circular bioeconomy case study integrating biomethane production from castor seed processing residues with digestate supported cassava cultivation. Batch biochemical methane potential testing showed that castor seed cake and husks can serve as viable anaerobic digestion substrates. A parallel cassava field trial showed treatment related differences in plant height, stem diameter, leaf number, SPAD index, and stalk count following graded digestate application. Together, the findings support anaerobic digestion as a practical platform for linking residue valorization, renewable energy generation, and nutrient recycling in Caribbean agricultural systems.
