Characterization of rice, coffee and cocoa crops residues as fuel of thermal power plant in Côte d’Ivoire

Worldwide, the wastes derived from food production are generated in elevated volumes annually. In particular, the cocoa industrial wastes represent a source of usable biomass for the elaboration of new products such as food, livestock feed, cosmetics, and chemical products, and they can even be used for the generation of biofuels. The cocoa industrial wastes include cocoa pod husk, mucilage, and bean shells, which contain compounds of interest for different industries. However, the lignocellulose content of these by-products requires a pretreatment to fully utilize them; thus, different biofuels can be produced, depending on the conversion technology used to obtain the highest biomass yield. Recent studies reported the use of cocoa industrial wastes for the production of solid, liquid, and gaseous biofuels; nevertheless, the most common use reported is as a direct combustion source, which is used to supply the same production plants. Therefore, the objective of this work is to carry out a review on the uses of the by-products generated from cocoa for the generation of biofuels, as well as the technological concept applied for the transformation. In addition, the future trends indicate the relevance of using catalysts in production to increase reactions in the conversion of compounds, including the use of statistical models to optimize the processing variables.

“…Property characterization is an important requirement in processing biomass for electricity generation [ 22 ]. Due to the hygroscopic nature and the moisture content of most agro-residues, the type of pre-treatment required to upgrade the fuel quality and the shelf-lives of the materials must be investigated before they could be confidently deployed.…”

“…Sheng and Azevedo (2005) proposed that the estimation of the biomass heating value should be conducted for various biomass component properties and chemical compositions [2]. Multiple studies have assessed the use of rice husks as fuels, such as biochar [3], for hot water production [4], for synthesis of mixed fuel for electric generation [5], solid fuel through torrefaction [6], fuel by uidized-bed combustion [7], power generation by gasi cation [8], three conversion technologies (hydrothermal carbonization with pelletization, pyrolysis, and anaerobic co-digestion processes) for rice husk-to-fuel [9], and thermal bioconversion, including ethanol production technologies [10]. Quispe et al (2017) studied various agricultural residues and transformed rice husks into fuel through pyrolysis [11].…”

Extremely lightweight of rice husks due to low specific gravity is disadvantageous for accelerating its usage. To overcome this disadvantage, rice husks are sometimes compacted, that is, pelletized or solidified to assist easy and cheap collection and hauling. However, the compaction process may negatively affect the properties of silica in the husk. In this study, the influence of the compaction process was studied through the solubility and physical properties of silica. Two types of fuels, pellet and stick fuels, were synthesized and their influence on the properties of the fuel ash was evaluated. Consequently, stick fuels were better than pellet fuels in terms of fertilizer use of the ash during their use in residential stoves and small commercial heaters. Contrastingly, rice husks in the existing form were better than stick fuels under washing conditions; however, rice husks had disadvantages in terms of cost and handling during collection and hauling. Selection of rice husks in their existing form or compacted rice husks must be carefully considered based on the business approaches of the stakeholders.
