“…Therefore, it indicates that methanogenic bacteria take advantage of this increase in the lignocellulosic was obtained in CPH. Syamsiro et al (2011) reported the value of 17.01 MJ•kg -1 for CPH. Since the upper heat capacity is influenced by the content of C, H, O, and N, the data compared to literature may vary.…”

The current study sought to determine the potential of cacao pod husks for energy use. Biogas potential, the kinetics of anaerobic digestion at bench scale, and physicochemical characterisation of materials were evaluated for cacao pod husks (CPH), depectinised cacao pod husks (CPH-D), and cacao pod husks treated by Pleurotus spp. (CPH-DF). These materials showed accumulated biogas productions of 314.86 ±4.45 l·kg−1 VS−1, 369.49 ±15.98 l·kg−1 VS−1, and 342.52 ±10.98 l·kg−1 VS−1, respectively. The calorific values in CPH-DF, CPH, and CHP-DF were 17.65 MJ·kg−1, 15.43 MJ·kg−1, and 17.21 MJ·kg−1, respectively. These values indicate that the evaluated materials have a high potential to be used as biofuels.

“…In order to obtain the appropriate size of the material for the milling stage, the CPHs were crushed in a hammer mill into smaller particles for easy use in a ball mill. The ball-milled CPHs were then screened to obtain a powder with a grain size of less than 1 mm, according to Syamsiro et al [20]; the ratio of the surface area of the pellet mass is the most important parameter for the combustion reaction. The weight of the sample used in the calorimeter crucible ranged between 0.8 g and 1.0 g. During the measurements, oxygen was supplied at a constant pressure of 44 bars.…”

Quantification and characterization of cocoa pod husks for electricity generation in Uganda

Background: Due to limited coverage, the electricity power supply in Uganda is an obstacle to the country's economic development. Utility firms in Uganda either lack the financial capacity to expand their grids to isolated rural areas or choose not to do so due to the low return on investment. Therefore, connecting households to minigrids represents an effective solution to providing power to remote/rural areas. This study evaluates the resource and technology of generating electrical energy from cocoa pod husks (CPHs), an agricultural residue/waste, generated in Uganda. The use of agricultural waste for energy generation is the most suitable option for the rural population in Uganda because of the availability of a raw material (biomass) for its production, which is pollutionfree (renewable and clean) and does not have competition for use. The inability to convert these solid wastes into useful products culminates into environmental related challenges, such as landfilling, climate change, pests, and diseases. Therefore, the aim of this study is to quantify the amount of generated CPHs and evaluate its potential for electricity generation in Uganda. Subsequently, we have been looking into the potential of CPHs as a feedstock for a thermochemical conversion process and the feasibility of a direct combustion technology. Results: The amount of CPHs generated in Uganda has been estimated. The physiochemical analysis has shown that the proportion of CPHs in the fresh pods is about 74%, which is nearly the same as in other studies. The dry matter content of CPHs has been found to be on an average of 19%, whereas ash content, moisture content, and the gross caloric value have been recorded to be 12.3%, 12.58%, and 17.5%, respectively. It seems therefore likely that 41.7 GJ of energy might be produced each year from CPHs in Uganda. Conclusion: This study has demonstrated that the CPHs are an important energy source. As there is an increasing trend in cocoa and CPH production in Uganda per year, the electricity production based on CPHs is sustainable and can be upgraded. The use of CPHs for energy conversion is therefore feasible, cost-efficient, and a solution to some environmental challenges.

“…Therefore, some researchers look to organic cocoa waste as a source for the production of biofuels and other biopolymers [37]: for example, they can be also used as activated carbon and catalyst in biodiesel production [38,39]. The ground and pressed cocoa pod husk can be transformed into bio-pellets [40], having similar combustion characteristics and ash content in comparison to other biomass products.…”

The sustainable management of waste from agricultural crops represents an urgent challenge. One possible solution considers waste as possible secondary raw materials for specific uses. Among these, the use of agricultural waste as a product for the assembly of panels for the sound absorption of living environments represents a particularly suitable solution. In this study, the acoustic properties of the cocoa pod husk were evaluated, using silicone as a binder. Different proportions of materials and thicknesses were evaluated. A Support Vector Machine (SVM)-based model with a Gaussian kernel was then used to predict the acoustic performance of composite materials. The results obtained suggest the adoption of this material for the acoustic correction of living environments and this methodology for the prediction of the acoustic behavior of materials.
