“…Few researches proved that co-substrates addition can improve methane yields by completing the lack of nutrients in the main substrate, adding the buffering capacity as well as improving microbial community to become better adapted to degrade the organic substances (Abouelenien et al, 2014;Nayono et al, 2010;Lehtomaki et al, 2007). Study by Nayono et al (2010) shows that co-digesting press water from municipal composting plant and food waste with bio-waste suspension from treatment plants had improved the methane yield at the maximum of 17.65% and 23.53%, respectively.…”

One of the alternative sources for clean energy is biogas. Generating energy from agrowaste and effluents can lessen environmental impacts. This study was conducted to determine the production of biogas from six potential substrates, i.e. goat dung (GD), chicken dung (CD), fish waste (FW), rice waste (RW), palm oil mill effluent (POME) and sewage sludge (SS) using industrial inoculum as catalysts. Biophysical characteristics were assessed using laboratory-based analyses, whereas the Bio-Methane Potential (BMP) assay was used to measure anaerobic biogas production in mesophilic condition for 20 consecutive days. Results revealed that rice waste with industrial inoculum produces the highest amount of biogas, followed by goat dung, chicken dung, fish waste, palm oil mill effluent and sewage sludge with total amount of 3508.9 mL, 2141 mL, 1885.7 mL, 1546.0 mL, 743.8 mL and 547.7 mL, respectively. In conclusion, all substrates used in this study can be combined with industrial inoculum would serve producing energy in a small-scale industry.

“…El monitoreo de la DQO en los experimentos es importante porque es un indicador de cuánta materia orgánica se está degradando para ser convertida en biogás (Nayono et al 2010) y se midió con el propósito de observar el efecto de la relación S:I en la producción final de dicho biogás. La figura 3 muestra la evolución de la DQO en los experimentos realizados, es importante señalar la similitud en la forma de las gráficas entre los reactores R1s y R2s con sus respectivos reactores testigo, R1b y R2b, que indican procesos de adaptación y funcionamiento similares a volúmenes idénticos de inóculo utilizado.…”

Palabras clave: digestión anaerobia, biogás, inóculo, sustrato RESUMENEn este trabajo se estudia mediante el proceso de digestión anaerobia (DA), la descomposición de materia orgánica de residuos alimenticios de cocina (sustrato) con lodo (inóculo) de una planta de tratamiento de aguas residuales con la finalidad de obtener biogás y determinar el potencial bioquímico de metano (PBM) al final del proceso. Los ensayos que se llevaron a cabo fueron con relaciones sustrato:inóculo (S:I) 1:2 y 1:3, en términos de sólidos volátiles (SV). En el transcurso de la DA en condiciones mesofílicas (35 ºC) y tiempos de residencia (TR) de 15 días, se midieron los parámetros más importantes que influyen en esta digestión: SV, sólidos totales (ST), demanda química de oxígeno (DQO) y pH. El biogás obtenido se purificó por medio de la eliminación de H 2 S y NH 3 con trampas de NaOH y H 2 SO 4 1M. En el caso de los experimentos con inóculo y sustrato se recuperaron en promedio 1.235 L de biogás con un 80.15 % de CH 4 y en los ensayos con inóculo sin sustrato 0.720 L de biogás con 90.47 % de CH 4 . La cuantificación de este gas se llevó a cabo por cromatografía de gases. Los resultados que se obtuvieron concuerdan favorablemente con la producción de biogás y la disminución de la materia o carga orgánica expresada como DQO. En la determinación de PBM se obtuvieron 124.82 y 127.89 mL CH 4 /g SV para experimentos S:I-1:3 y para la relación 1:2, 103.39 y 116.27 mL CH 4 /g SV.Key words: anaerobic digestion, biogas, inoculum, substrate ABSTRACTIn this work we studied the decomposition of organic matter of food kitchen wastes (substrate) by sewage sludge (inoculum) from a wastewater treatment plant, through the process of anaerobic digestion (AD) in order to obtain biogas and to determine the biochemical methane potential (BMP) at the end of this process. The tests were performed with substrate:inoculum ratios 1:2 and 1:3, in terms of volatile solids (VS).
