The potential of bioenergy production from cocoa pods residues and cashew peduncle residues using two pathways - anaerobic digestion and hydrothermal carbonization processes was evaluated. Mono digestion of cashew peduncle is only possible up to an organic loading rate (OLR) of 3.0 kgVS/m3.day in a semi-continuous reactor. However digestion of cashew bagasse and cocoa pods were stable up to an OLR of 4.0 kgVS/m3.day. Using surface response models, the effect of process temperature, reaction time and heating rate on the yield, heating value and ash content of the hydrochar was studied.<eng>
