“…digestión anaerobia se presentan en la Tabla 4. El T 9 (Corteza + Cilindro central de la yuca + Inóculo de la biodigestión de torta de piñón) demostró obtener mayor contenido nutricional en N y K. Diferencias significativas fueron encontradas estudiando el Ca, con mayores respuestas para T siendo diferentes cantidad potencial de degradación del material crudo, siendo que aproximadamente el 70% de los volátiles encontrados de los residuos de la yuca están compuestos de compuestos biodegradables conocidos (Suzuki et al, 2012).…”

La presente investigación tuvo por objetivo evaluar la producción de biogás a partir de fibras de la yuca (Manihot esculenta Crantz) con diferentes inóculos y caracterización química de los substratos biodigeridos. Los tratamientos fueron distribuidos de la siguiente manera: T . Corteza de yuca + agua, T . 1 2 Cilindro central de yuca + agua, T . Corteza + Cilindro central de yuca + agua, T . Corteza de yuca + 3 4 Inóculo de Biodigestión de estiércol bovino, T . Cilindro central de yuca + Inóculo de Biodigestión de 5 estiércol bovino, T . Corteza + Cilindro central de yuca + Inóculo de Biodigestión de estiércol bovino, T . 6 7 Corteza de yuca + Inóculo de biodigestión de torta de piñón, T . Cilindro central de yuca + Inóculo de 8 biodigestión de torta de piñón, T . Corteza + Cilindro central de yuca + Inóculo de biodigestión de torta de 9 piñón, T . Corteza de yuca + Inóculo de biodigestión de estiércol porcino, T . Cilindro central de yuca + 10 11 Inóculo de biodigestión de estiércol porcino, T . Corteza + Cilindro central de yuca + Inóculo de 12 biodigestión de estiércol porcino. Fue determinada la producción de biogás diariamente, y además se efectuó la medición del CH y CO con el método Orsat. Se analizaron parámetros físico y químico de los 4 2 sustratos biodigeridos. La biodigestión del cilindro central de la yuca o de la corteza usando como inoculantes la biodigestión de torta de piñón o estiércol bovino producen 71,67 % de CH . Los substratos 4 biodigeridos contienen macro y micronutrientes con potencial uso en la agricultura.

“…[35][36][37] Another possibility is to use a cosubstrate with more accessible nutrients to reduce the HRT, as for example manure from monogastric species, such as swine manure [38] and poultry manure. [39] These species produce manure with nutrients that are more easily degradable and thus rapidly available leading to higher rates of biogas generation. In this way, the period of metabolization of the methanogenic bacteria is reduced by avoiding the acidification.…”

Several studies have shown that it is necessary to use a two-stage anaerobic reactor in biogas production with manipueira as a substrate. The objective of this study is to show the possibility of producing good quality biogas from a single-stage anaerobic reactor using manipueira and cattle manure as substrates. Five scenarios of codigestion are simulated in five digesters with different manipueira/manure ratios. The only digester that has a good result is the digester that is fed with 75% of manipueira and 25% of cattle manure. Under these conditions, biogas is produced with an average methane concentration of 62% the hydraulic retention time of the codigestion process is 30 days. The other digesters show that an excess of manipueira acidifies the codigestion process; such acidification can result in the severe inhibition of methanogenesis because of the accumulation of volatile fatty acids. On the other hand, an excess of cattle manure results in mixtures with a high concentration of lignin, cellulose, and hemicellulose mixtures, which, negatively influences the growth rate of methanogenic bacteria. Thus, using manipueira as cosubstrate, it is possible to produce a high-quality biogas in a single-stage anaerobic reactor.

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.
