Resumo: One way to take advantage of the energy available in the waste, stabilize and reduce the volume of the organic fraction to be sent to landfills is through anaerobic digesters. The research aims to evaluate the production of methane gas from the anaerobic digestion of the organic fraction of the MSW of the Sanitary Landfill of Agreste Alagoano, through tests of Methane Biochemical Potential, with and without the use of inoculum. For this purpose, six 1L discontinuous hydraulic flow reactors were used, with a reaction volume of 400mL, three reactors with inoculum and three others with the organic fraction without inoculum. The greatest potential was observed in the reactors with inoculum, of 7926.31 mL, with peak production on the 10th day of operation, and also obtained the highest methane production rate of 1491.16 mL.h-1. The reactors without inoculum had lower potential and methane production rate, 1020.42mL and 28.40mL.h-1, their maximum production occurred on the 30th day of operation. With this, it is verified the importance of the use of inoculum for a greater potential generation of methane gas in the anaerobic digestion of MSW of the landfill under study, which can be used as an alternative source of energy for domestic and industrial purposes.

La investigación tiene como objetivo evaluar la producción de gas metano a partir de la digestión anaeróbica de la fracción orgánica de los RSU del Relleno Sanitario de Agreste Alagoano, mediante pruebas de Potencial Bioquímico de Metano, con y sin la presencia del uso de inóculo. Para ello se utilizaron seis reactores de flujo hidráulico discontinuo de 1L, con un volumen de reacción de 400mL, tres reactores con inóculo y otros tres con la fracción orgánica sin inóculo. El mayor potencial se observó en los reactores con inóculo, de 7926,31 mL, con pico de producción al décimo día de operación, y también obtuvo la mayor tasa de producción de metano de 1491,16 mL.h-1. Los reactores sin inóculo tuvieron menor potencial y tasa de producción de metano, 1020.42mL y 28.40mL.h-1, su producción máxima se dio al día 30 de operación. Con esto, se comprueba la importancia del uso de inóculo para una mayor generación potencial de gas metano en la digestión anaeróbica de RSU del relleno sanitario en estudio, el cual puede ser utilizado como fuente alternativa de energía para fines domésticos e industriales.Uma maneira de aproveitar a energia disponível nos resíduos, estabilizar e reduzir o volume da fração orgânica a ser encaminhado para aterros é através dos digestores anaeróbios. A pesquisa tem por objetivo avaliar a produção de gás metano provenientes da digestão anaeróbia da fração orgânica dos RSU do Aterro Sanitário do Agreste Alagoano, através de ensaios de Potencial Bioquímico do Metano, com e sem a presença do uso de inóculo. Para isso foram utilizados seis reatores de fluxo hidráulico descontínuuo de 1L, com volume reacional de 400mL, sendo três reatores com inóculo e outros três com a fração orgânica sem inóculo. O maior potencial foi observado nos reatores com inóculo, de 7926,31 mL, com pico de produção no 10º dia de operação, e obteve também a maior taxa de produção de metano de 1491,16 mL.h-1. Os reatores sem inóculo obtiveram menor potencial e taxa de produção de metano, 1020,42mL e 28,40mL.h-1, sua produção máxima ocorreu ao 30º dia de operação. Com isso, verifica-se a importância do uso de inóculo para um maior potencial geração de gás metano na digestão anaeróbia de RSU do aterro em estudo, que pode ser utilizado como fonte alternativa de energia para fins domésticos e industriais.Research, Society and Development2021-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1540710.33448/rsd-v10i6.15407Research, Society and Development; Vol. 10 No. 6; e0110615407Research, Society and Development; Vol. 10 Núm. 6; e0110615407Research, Society and Development; v. 10 n. 6; e01106154072525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15407/13764Copyright (c) 2021 Mayco Sullivan Araujo de Santana; Esterphany Cerqueira de Carvalho; Nélia Henriques Calladohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Santana, Mayco Sullivan Araujo de Carvalho, Esterphany Cerqueira deCallado, Nélia Henriques 2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15407Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:14.187229Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
