Recent development of microbial electrochemical technologies has allowed microbial electrosynthesis (MES) of organic molecules with microbial electrolysis cell treating waste organic matter. An electrolytic cell with a MES cathode (ME-ME cell) can produce soluble organic molecules with higher market price than biomethane, and thus satisfy both economic and environmental interest. However, the sustainability of bioanode activity could become a major concern. In this work, a 15-liter ME-ME reactor was designed with specific electrode configurations. An electrochemical model was established to assess the feasibility and possible performance of the design, considering the “aging” effect of the bioanode. The reactor was then built and operated for performance evaluation as well as bioanode regeneration assay. Biowaste from an industrial deconditioning platform was used as substrate for bioanode. The COD removal rate in the anodic chamber reached 0.83 g day-1 L-1 of anolyte and the anodic coulombic efficiency reached 98.6%. Acetate was produced with a rate of 0.53 g day-1 L-1 of catholyte, reaching a maximum concentration of 8.3 g L-1. A potential difference was applied between the bioanode and biocathode independent of reference electrodes. The active biocathode was dominated by members of the Genus Pseudomonas, rarely reported so far for MES activity.

“…Esto sugiere que los microrganismos ruminales degradan adecuadamente desperdicios vegetales (a excepción de SO) después de 72 h de incubación en las condiciones descritas. Sin embargo, la digestión anaerobia es afectada por la temperatura, pH, relación sólidos-líquidos, tipo de sustrato (Li et al 2016, Sen et al 2016, y tipo y densidad del inóculo (Islas-Espinosa et al 2017). En este contexto, en el presente estudio se proporcionaron las condiciones óptimas para los microorganismos ruminales de acuerdo con la metodología descrita por Theodorou et al (1994).…”

“…Sin embargo, la fermentación de LS, BOV, BOB y OF no provocó los mismos efectos, lo que sugiere un efecto acidificante menor que se relaciona con bajo contenido de azúcares solubles (Scano et al 2014, Li et al 2016. No obstante, a pesar de los cambios en el pH al final de la incubación, éste fue de 6.5 a 7, el cual está dentro del rango ideal (6.5 a 7.5) para los microorganismos metanogénicos (Sen et al 2016) y es similar a lo reportado por Sánchez-Reyes et al (2016) con valores de 6.94 a 7.95 en digestión anaerobia de frutas y vegetales.…”

Palabras clave: metano, desechos orgánicos, producción de gas, bioenergía, residuos vegetales RESUMEN La creciente demanda de alimentos en áreas urbanas genera cada vez mayor cantidad de desperdicios orgánicos, incluyendo residuos vegetales. El manejo de estos residuos vegetales causa emisiones de gases efecto invernadero (GEI) por su recolección, transporte, y depósito en vertederos. Para identificar su potencial de GEI, en un mercado de alimentos se recolectaron residuos de hojas de lechuga (LS), de col (BOV), de coliflor (BOB), de maíz (HZM), de espinaca (SO) y de nopal (OF), se fermentaron in vitro usando líquido ruminal como inóculo y se compararon con heno de avena (AS), heno de alfalfa (AH) y ensilado de maíz (EZM), forrajes utilizados con frecuencia en la alimentación de rumiantes. Las variables fueron degradación in vitro de la materia seca (DIVMS), pH, cinética de producción de gas y concentración de metano (CH4). La fermentación se realizó durante 96 h a 39 ºC y las muestras de gas para medir la concentración de CH4 se tomaron a 9, 12, 24, 34 y 48 h de incubación. La DIVMS de LS, BOV, BOB, HZM y OF fue 12.8 % mayor a AS, AH y EZM. Entre las 9 y 12 h de incubación la emisión de CH4 a partir de BOV, BOB and HZM fue 44.8 % superior a los tres forrajes. La principal conclusión es que estos residuos vegetales son degradados adecuadamente por los microorganismos ruminales y, por lo tanto, se pueden usar para la producción de biogás en áreas urbanas para disminuir su depósito en vertederos.Key words: methane, organic wastes, gas production, bioenergy, vegetable residues ABSTRACTThe growing demand for food in urban areas generates an increasing amount of organic wastes, including vegetable residues.

“…However, further purification of ethanol through distillation is an energy-demanding process that produces about 450 L of ethanol/ton of dry corn (McKendry 2002). The end product after fermentation process can be utilized as feedstock for cattle or can be used in boilers for further gasification method (Coombs 1996;Sen et al 2016). Till date, there are no proper strategies for improving substrate conversion efficiency of the process.…”

There is continuous increase in quantum and variety of waste being generated by anthropogenic activities. Burgeoning amount of waste being generated has potential to harm the environment and human health. Aggravating the problem, ever-increasing energy demand is putting strain on the non-renewable sources of energy and there is huge gap between the demand and supply of energy. This has led the scientific communities to adopt innovative methods to reduce, reuse and recycle them. Therefore, there is an urgent need to minimize the quantity of waste and meet the current demand profile of energy is required; technologies to recover energy from waste can play a vital role in substantial energy recovery and reduction in waste for final disposal; in addition to meet the rising energy requirement. Generating power from waste has greatly reduced the environmental impact and dependency on fossil fuels for electricity generation. Economically also it is an optimal solution for recovery of heat and power from waste. This paper gives an overview of energy potential stored in waste, major available waste-to-energy technologies and also strategic action plan for implementation of these technologies.
