Abstract

Biomass waste conversion to biogas through anaerobic digestion offers an array of benefits from disposal management, clean energy provision, and economic inclusion. Cocoa processing wastes are abundant, yet their recovery alternatives are still underexplored in Indonesia. Therefore, this study emerges to investigate the potential of utilizing cocoa pod husk (CPH) and cocoa bean shell (CBS) in a mono-digestion system. Waste characterization was done and continued with bio-methane potential test (BMP) with OLR 2.3 g COD/day for 22 days at 35 ℃. Specific methane production (SMP) of CBS was higher (0.31 L methane/g COD) than CPH (0.19 L methane/g COD) possibly owing to CPH recalcitrant nature. To evaluate the biogas potential of cocoa farmers in Indonesia, theoretical biogas production was calculated by estimating CPH and CBS in Central Java, Special Regions of Yogyakarta, and Aceh obtained from literature study. CPH production of each cacao farmer in Indonesia ranging from 146 to 4,375 kg/month and the CBS from 5 to 138 kg/month. Using the biogas yield from the experimental work, this study calculated the theoretical potential to produce biogas within hydraulic retention time (HRT) 20 days i.e. as much as 2.54 to 76.22 m3 from CPH and 0.1 to 4.0 m3 from CBS. The finding highlights that the low availability of CBS might hinder the implementation despite CBS showed higher SMP. This aligns with the case study in Gunung Kidul, Indonesia in which CPH offers more biogas potential due to its abundance.
