Productividad de metano a partir de residuos de cultivo de maíz y frijol

Productivity of methane was measured from corn and beans residues, processed separately and together. The Department of Science and Production, responsible for crop production, reports about 15,000 kg/ha of corn residue and lesser amount of beans that are normally left in the field and turend over. This activity does not use the potential energy of the waste, so this study aims to estimate the amount of methane that can be produced from the anaerobic digestion of these crops in Zamorano, allowing for an estimate of the resource available for energy electricity and the production of fertilizer. Methane production from corn and bean residues was determined separately and together with percentages of 30:70, 50:50 and 70:30 respectively. Both substrates can be used for the production of methane individually or together, however the best productivity was recorded for corn residue operated at an organic load of 4 kg VS / m 3 resulting IPM 0.288 m 3 CH4 / kg SV. The amount of methane that can be produced using all of the corn residue is 416.569 m 3 to be transformed into energy by a generator with 33% efficiency can provide 1,518 MWh of energy that could contribute 30% from the annual energy consumption from the EAP.
