Ecuador is a country where three sectors with bioenergy potential have been identifi ed: fi rstly, agriculture, with products such as rice, bananas, cocoa, coff ee, sugar cane, hard corn, African palm, hearts of palm, pineapple, and plantain. Th e second is the livestock sector, with poultry, pig, and beef activities. Th e third is the forester. The residues generated by Musaceae (Banana and Plantain) are not well used effi ciently because they are disposed of in the open air and present environmental and economic problems for banana growers, however, this fruit off ers the opportunity to obtain valueadded bioproducts due to its chemical composition. Musaceae crops have been established predominantly in lands with a high mechanized agricultural vocation and with great hydrological wealth, these areas are of medium and high vulnerability to productive processes, and are not recommended fo...

The main objective of this research was to evaluate the biogas production from cassava fibers (Manihot esculenta Crantz) with different inocula and chemical characterization of the biodigested substrates. The treatments were distributed as follows: T . Cassava peel + water, T . Cassava + water central cylinder, T . 1 2 3 Cassava peel + central cylinder + water, T . Cassava peel + Bovine manure biodigestion inoculum, T . 4 5 Cassava central cylinder + Bovine manure biodigestion inoculum, T . Peel + cassava central cylinder + 6 Bovine manure biodigestion inoculum, T . Cassava peel + Physic nut seed cake biodigestion inoculum, T . 7 8 Cassava central cylinder + Physic nut seed cake biodigestion inoculum, T . Cassava peel + central 9 cylinder + Physic nut seed cake biodigestion inoculum, T . Cassava peel + pig manure biodigestion 10 inoculum, T . Cassava central cylinder + pig manure biodige...

Anaerobic digestion enables the degradation of the biodegradable organic fraction present in solid waste, transforming it into biogas with high methane content and high energy use, and a fi nal residue with a high rate of destruction of pathogenic microorganisms which meets the conditions to be used as a soil improver and biofertilizer. In this context, the production of biogas and methane gas from the anaerobic digestion of two varieties of cocoa (CCN-51 and Nacional) was evaluated and the obtained substrate was nutritionally characterized. Th e following treatments were studied: T1 Shell CCN-51 (20% ST); T2 Shell CCN-51 (30% ST); T3 Slime CCN-51; T4 Shell CCN-51 + Slime CCN-51 (20% ST); T5 Shell CCN-51 + Slime CCN-51 (30% ST), T6 Shell Nacional (20% ST); T7 Shell de Nacional (30% ST); T8 Slime Nacional; T9 Shell de Nacional + Slime Nacional (20% ST); T10 Shell Nacional + Slime Nacional...

In this work, the behavior and physicochemical characteristics of fruits, seeds, and the oil extracted from three promising sprocket lines CP041, CP052, and CP054 with degrees of maturation were evaluated: light green, yellow, yellowish-brown, and dark brown. Th e samples were obtained from the germplasm bank of the Portoviejo Experimental Station of the National Institute for Agricultural Research (INIAP-EEP), Manabí, Ecuador. In the statistical analysis, it was determined that the ripe fruits were the ones that presented the highest percentage of oil content, being the line CP041 the one that presented the highest content. In the percentage of seeds in nuts, the CP041 line had a higher yield than the CP054 line. As for proteins, the CP041 line stood out, in the percentage of fi ber and humidity CP052 and the percentage of ash CP054. In line CP041, the light green fruit oil had a highe...
