“…Qiao et al (2011) shows a slight reduction in the production of biogas (identically with methane) from kitchen waste by the hydrothermal pre-treatment at 170°C for 1 hour. Other types of biomass such as pig manure, cow manure, mixed vegetables and fruit, or sewage sludge showed an increase of the gas production.…”

Dlabaja T., Malaťák J., 2013. Optimization of anaerobic fermentation of kitchen waste. Res. Agr. Eng., 59: 1-8.Anaerobic fermentation is a suitable method of energetic and material utilisation of waste coming from restaurants and canteens. Laboratory experiments of wet anaerobic fermentation were performed in a continuous reactor and in batch reactors under mesophilic conditions. Effects of hydraulic retention time, organic loading rate, period of feeding and recirculation of digestate were examined in the continuous reactor. Effects of substrate pre-treatment (crushing, heating, freezing) were examined in the batch reactors. Degree of substrate degradation ranged between 83-85% within hydraulic retention time of 2-30 days. Appropriate organic loading rate was found in the range 2-3 kg of volatile solids per m 3 /day. Recirculation of digestate (both an inoculum for fresh substrate and replacement of fresh water supply)caused an increase in ammonia concentration and led to immediate inhibition of the process. The results further showed a positive effect of substrate pre-treatment in the initial phase of fermentation. However, degree of degradation did not show a significant increase for the period of 20 days of fermentation.

“…The authors ascribed this phenomenon to the arrangement of an intractable copolymer and melanoidin (Maillard reaction products). Under related working conditions (170 • C, 1 h), Qiao et al (2011) observed that both biogas and methane generation from anaerobically treated FW and cow manure were diminished by 3.4 and 7.5% respectively as a result of lower pH and higher VFAs. Ma et al (2011) reported a 24% enhancement in CH 4 production when FW was treated at 120 • C.…”

ResumenEl bajo grado de tecnificación de la mayoría de las granjas en el departamento de Cundinamarca, conlleva a una alta tasa de generación de residuos agroindustriales, haciendo indispensable la evaluación de alternativas de valorización. En este trabajo se determinó el potencial de producción de biogás de los residuos agroindustriales en el departamento de Cundinamarca a través de digestión anaerobia. El potencial se estableció a partir de tres acercamientos metodológicos que incluían la evaluación de la generación de residuos en cada uno de los municipios, cálculo del potencial por tipo de biomasa residual en el departamento e identificación de tres regiones con el mayor potencial de producción de biogás. El cálculo del potencial se soportó en una recopilación, estandarización y procesamiento de la información disponible de áreas cultivadas y residuos generados en cada sector y/o actividad. Cundinamarca tiene un potencial promedio de biogás de 1.117.567TJ/año calculado por la transformación de los residuos agroindustriales a través de proceso anaerobio. Los residuos de mayor aporte en el potencial encontrado corresponden a aquellos generados por actividades relacionadas con los cultivos de café, caña panelera, arveja, papa; excretas bovinas y avícolas. Las regiones que podrían cobijar sistemas centralizados se identificaron en torno a los municipios de Fómeque, Guachetá y Anapoima, los cuales presentaron mayor potencial. El potencial estimado para estas regiones fue de 89.651, 127.513, 58.541TJ/año para la región 1, región 2 y región 3, los cuales son similares a los reportados para plantas de biogás en varias regiones del mundo. Palabras clave: Biogás, biomasa, co-digestión anaerobia, potencial de biogás, residuos agro-industriales. AbstractThe low level of technology in the farms of the Cundinamarca department, leads to a high rate of agroindustrial waste generation, making important the assessment of valorization alternatives. In this work, the biogas production potential of agro-industrial residues in the department of Cundinamarca was established through anaerobic digestion. The potential has been established from three methodological approaches, including the assessment of waste generation in each of the municipalities, calculation of potential by type of residual biomass in the department and identification of three regions with the greatest potential for biogas production. The estimation of the potential was supported in the collection,
