Experimental Study of Biogas Production from Cow Dung as an Alternative for Fossil Fuels

Abstract

To treat the problem of fossil fuel usage and greenhouse gas emissions, biogas is considered a potential source of clean renewable energy. The aim of the work is to analyze the amount of biogas and ph from cow dung when an anaerobic digester operates in the mesophilic mode. In this study is presented the experimental investigation of biogas production from cow dung as an alternative energy resource. This is work using an 18 Liters capacity plastic as prototype biogas plant, plant to inspect the anaerobic digestion in producing biogas. The digester was batch operated and daily gas produced from the plant was observed for 30 days. The digester was fed within the ratio of 1:1 of dung to water respectively. The operating temperatures of the digester were maintained within mesophilic conditions. The Biogas production from cow dung fluctuates from the first day to the thirtieth day between 0 and 340 ml. The pH of cow dung is gradual reduction within the retention period.

Potencial de biogás, energía eléctrica, reducción de CO2eq y rentabilidad de biodigestor-motogenerador para establos lecheros en México

“…Esta tecnología es clave en la disminución de emisiones de metano (CH4), un potente gas de efecto invernadero, que se libera durante la descomposición natural del estiércol (Solano, 2019;Alvarado, De Oliveira, De Oliveira, Damasceno, y Alvez, 2020;Ngo, Ball, y Shahsavari, 2021). Además, la DA facilita la producción de biogás, reconocido como una fuente de energía renovable y sostenible, que contribuye significativamente a la reducción de gases de efecto invernadero al reemplazar combustibles fósiles en la generación de calor y electricidad (Benali, Hamad, y Hamad, 2019;Solano, 2019;Alvarado et al, 2020;Ngo et al, 2021;Sanaye y Yazdani, 2022). Según Ngo et al (2021), el tratamiento de una tonelada de desechos mediante la DA puede resultar en una disminución de 0.143 toneladas de equivalente de CO2.…”

Development of a Locally Sourced Miniature Facility Capable of Transforming Bio-Waste into Renewable Energy

“…Fossil fuels are the main source of energy on the planet (Benali, Hamad, and Hamad, 2019). This kind of energy source releases a significant amount of carbon dioxide gas, one of the main greenhouse gas contributors.…”

Influence of pH and the Insulation of Reactor on The Biogas Production of Livestock Waste by Batch Anaerobic Reactor

“…Cunsheng et al [19] reported that codigestion of cattle manure with food waste in batch mode at an optimal ratio of 2:1 (manure: food waste) increased methane production by 41%, from 2624 ml to 3725 ml, compared to mono-digestion. Benali et al [20] Effect of solid concentrations on anaerobic digestion of cow manure. This research aims to determine the optimum water dilution which will produce a high biogas yield.…”
