The bioenergy has turned into a good alternative for reducing the emission of pollutant gases. In Brazil, the use of this type of energy has increased in the last decades. Biogas, produced from cassava, appears as an alternative fuel to fossil fuels and, also, becomes economically competitive, since this is a low cost carbon source. Anaerobic biodigesters that use renewable raw materials are known as a technology with great potential for biogas production which is considered a source of clean energy. Biogas produces sustainable energy and consists mainly of methane (60%) and carbon dioxide (35% to 40%). This study presents the biogas potential from the cassava processing residual water for the production of dry flour (manipueira). The results of this study indicated that the biogas potential is 1.389.312 cm 3 per year from a single-stage reactor with a capacity of 60 liters using manipueira as substrate and inoculated with cattle manure, which could provide a generation of electricity of 214 kwh/year.

“…Simulation of the biological processes of AD and DF was performed in Aspen Plus V9 software, the Soave-Redlich-Kwong (SRK) method was chosen as it correlates and calculates the mole fractions and activity coefficients. In addition, the SRK model is suitable for vapor-liquid equilibrium (VLE) (Madeira et al, 2017). The starting point for the simulation of AD was the ADM1 model, which relates the stoichiometric equations for the stages of hydrolysis, acidogenesis, acetogenesis, and methanogenesis (Serrano, 2010).…”

“…These differences in biogas production yields are probably primarily related to the different compositions of proteins, fats, and carbohydrates considered for CFM and SM (Table 1). Higher carbohydrate content of CFM resulted in higher H 2 production yields for blend 7, as carbohydrates represent the most suitable substrate for DF (pathways n°39 and 40, Supplementary Table S2), whereas higher protein content of SM resulted to lower C/N ratios that may inhibit DF as described by the ammonia inhibition modules integrated into the model (Madeira et al, 2017;Serrano, 2011). These results are in good agreement with the findings of previous experimental studies (Zhu et al, 2008;Ghimire et al, 2015), which have indicated that low C/N ratio and high concentration of ammonium ion (NH 4 + ) inhibit H 2 production during DF when SM is used as the only substrate, with maximum production yields of 3.65 ml H 2 •VS −1 .…”

This study provides the first overview in Colombia on energy recovery potential by anaerobic digestion (AD) and dark fermentation (DF) of three different residual biomasses: coffee mucilage (CFM), cocoa mucilage (CCM), and swine manure (SM). First, AD and DF models were developed based on the ADM1 model. Then, simulated biogas production yields were compared to experimental data to validate the models. The results of comparative simulations indicate that energy recovery potentials from biogas for the different Colombian departments range from 148 to 48,990 toe, according to the local production amounts of CFM, CCM, and SM in 2017. The study provides crucial information that can be used to assess the best design, operation mode, and locations of AD and DF plants in Colombia. The results indicate that biogas production performances and energy recovery yields improve by increasing CFM/SM and/or CCM/SM ratios of the feed, and by increasing organic load from 2 to 26 gCOD∙l−1.

“…There are many studies addressing exergy analysis of hydrogen production by steam reforming, 20‐22 the main difference of the study presented in this study in relation to the studies described in the literature is the crossing of different biogas (different concentrations of methane), that allows an analysis that relates the production of hydrogen with the input biogas, showing how the variation of hydrogen is related to input biogas in the steam reforming, pointing out ways to improve the exergy efficiency of the plant, enabling improvements in the production potential of hydrogen.…”

The use of hydrogen as clean energy has been becoming more attractive, because it is the most abundant element in the universe, the lightest fuel and richest in energy per unit mass. Cassava is a commodity of great importance in several underdeveloped countries, where its products and by‐products are of great importance in the food chain of these nations. Thus, the possibility of produce hydrogen from cassava wastewater (manipueira) not only recover the energy contained in cassava wastes but also eliminate most of the hydrocyanic acid contamination problems. The aim of this study is to perform the exergy analysis of hydrogen production by steam reforming from different biogases and analyze the hydrogen production in many different scenarios, showing that cassava wastewater has great potential for hydrogen production. Four different types of methane concentration were studied: 70.25, 75.5, 80.9, and 97.14%. The exergy analysis of the process and the production of hydrogen were calculated through simulation of the process using HYSYS software version 8.0. The results from these analyzes showed this is an alternative environmentally attractive and adding values to the cassava supply chain.
