“…Scaling-up of pectin extraction from CPH can also be economically feasible, provided that two fundamental steps are considered; the preparation of the raw material (drying and decreasing particle size) and acid used in the hydrolysis (citric acid). If the direct and indirect costs of facilities are also considered, this would give an internal rate of return of 33% and a 4 years investment recovery, which indicates its profitability [61].…”

Cocoa pod husk (CPH) is the main by-product (ca. 70-75% weight of whole fruit) of the cocoa harvest, an important and economic crop in developing countries. It is a rich source of minerals (particularly potassium), fibre (including lignin, cellulose, hemicellulose and pectin) and antioxidants (e.g. phenolic acids). An existing practise is the return of CPH to soil with potential benefits (or disadvantages) for cocoa productivity and soil sustainability that have not been fully characterised. Currently, alternative low-value applications of CPH include its use as animal feed, as a starting material for soap making and activated carbon. Other biotechnological valorisation potentials for CPH and its fractions include the production of bio-fuels and their incorporation in food systems. Physical, chemical or biological pretreatment approaches are needed in order to achieve desirable fractions in a cost-effective and sustainable manner for novel applications in food and non-food sectors.

“…The National Renewable Energy Laboratory (NREL) database was used to obtain data on physicochemical lignin and cellulose properties [22]. Concerning pectin, the molecular structure of the pectin monomer was designed in the program, and its properties were estimated according to Lopez et al (2017) [23]. The remaining components listed in Table 1 are available in the Aspen library and were added to the simulation.…”

Orange-juice production represents a significant, world-leading economic sector in Brazil. Orange processing residues, however, correspond to 50% to 60% of the in natura fruit mass. Despite the high amount of generated waste, which is disposed of in landfills or used as raw material to produce low-value animal feed, studies on the use of this waste are still developing in Brazil. However, orange peels contain compounds that can be precursors to higher value-added products in different sectors. Therefore, this study presents a conceptual proposal for a biorefinery integrated into the orange-juice-production route to assess integrated processes’ technical, environmental, and economic performance to convert waste into chemicals, fuels, and energy. A stationary process simulation model was developed to analyze the manufacturing of four products, namely, D-limonene, pectin, biomethane, and electricity, comparing the results to the conventional feed production route according to generated revenue and environmental impacts. The results indicate that pectin production is the highest financial-return route, presenting the most significant environmental impact, whereas D-limonene production is more attractive, generating the second-highest revenue with the lowest associated environmental impacts.

“…Nowadays, the environmental sustainability of processes is in the scientific community spotlight. Agricultural residues can provide large amounts of biomass as feedstock for biofuel and bioenergy production [5,8]. Agricultural biomass residues are composed of cellulose, hemicellulose, and lignin and possess a highenergy content [3].…”

Biogas represents a green energy source that has received major attention as an alternative for fossil fuel depletion. In this work, corn crop residues were used as feedstock for biogas production by anaerobic digestion. The effect of alkaline pretreatment was also evaluated. Proximate analysis was performed to inoculum samples in order to determine volatile and total solids content. Experiments were performed in duplicate varying both parameter particle size (0.5 mm, 1 mm, 2 mm, and in natura) and inoculum to substrate ratio (1:1, 2:1, and 3:1). The highest amount of biogas (392.75 mL) was obtained from corn stalk without pretreatment using 1 mm particle size and 1:1 inoculum to substrate (I:S) ratio. In addition, the highest yield (6.29x10-2 m 3 / kg SV substrate) was achieved for pretreated corn leaf biomass using in natura particle size and 3:1 I:S ratio, which confirms that alkaline pretreatment facilitates the hydrolysis stage during the anaerobic digestion process. These results suggested that alkaline pretreatment enhances biogas production from corn crop residual wastes.
