A large amount of litter is generated in industrial-scale animal breeding, and this is recognized as a big problem in animal-breeding technology. Troublesome waste may, however, be regarded as a useful, easily accessible cosubstrate for the production of biogas and semi-liquid residue suitable for fertilizing plants. Its utilization problem can thus be integrated with the production of an environmentally friendly energy carrier: biomethane. The results of litter decomposition are visible just after excretion as odor compounds are emitted. Animal litter of high protein concentration and moisture >40% undergoes complex biochemical decomposition that is closely related to the intensive emission of ammonia. It directly affects living conditions of animals in rooms [1]. The amount and composition of the gaseous mixture produced from litter depends, among other things, on: temperature, moisture level, mixing frequency, bedding type, composition and Pol. J. Environ. Stud. Vol. 26, No. 3 (2017) AbstractThe recommended process conditions and problems reported during anaerobic (co-)fermentation of waste biomass rich in proteins are discussed. Theoretical potentials of the individual biogas components (CH 4 , CO 2 , NH 3 , H 2 S) formed during chemical decomposition of aminoacids -feed additives commonly used in feeding animals -are shown, and we discuss side production of odors, e.g., ammonia and organic sulphur compounds. We also suggest the potential alternative production of biohydrogen (a future energy carrier) from specific waste biomass with high protein content.

“…La cantidad de nitrógeno y carbono presente en los residuos es un factor crucial en la producción de biogás [21]. Una relación C/N elevada puede generar deficiencia de nutrientes para el crecimiento y reproducción de los microorganismos; una relación C/N muy baja puede producir inhibición de la metanogénesis debido a altas concentraciones de nitrógeno amoniacal (total o libre) [9].…”

ResumenLa digestión anaerobia es un proceso ampliamente utilizado para el tratamiento de los lodos producidos en las plantas de tratamiento de agua residual, debido a sus ventajas técnicas y económicas. Este artículo presenta un estudio en el que se evaluó la co-digestión de lodos de aguas residuales con residuos de alimentos (RA) como una estrategia para optimizar la digestión de los lodos. Se realizaron mono-digestiones y co-digestiones de los sustratos en condiciones mesofílicas (35°C) usando reactores por lotes. Los lodos utilizados fueron: lodo primario (LP), lodo secundario espesado (LSE) y una mezcla de LP con LSE en la proporción 60:40 con base en sólidos totales (LP:LSE). Las co-digestiones se realizaron usando distintas proporciones de mezclas de los sustratos con base en sólidos volátiles totales: LP:RA=30:70, LP:RA=50:50, LP:RA=70:30 y (LP+LSE):RA=70:30. La máxima producción de metano, 0,25LCH 4 /gSVadicionado, se obtuvo para la mezcla LP:RA=30:70, presentando una producción 32% mayor que la obtenida en la mono-digestión del lodo primario. Palabras clave: co-digestión, producción de metano, lodo primario, lodo secundario espesado, residuos de alimentos. AbstractAnaerobic digestion is a process widely used for the treatment of sludge generated during wastewater treatment, due to its technical and economic advantages. This paper presents a study in which the co-digestion of sewage sludge with food waste (FW) was evaluated as a strategy for optimizing the digestion of sludge. Mono-digestions and co-digestions of the substrates were performed under mesophilic conditions (35°C) using batch reactors. The sludge used were: primary sludge (PS), thickened secondary sludge (TSS), and a mixture of PS with TSS in a ratio 60:40 based on total solids (PS:TSS). The co-digestions were performed using different ratios of mixtures of the substrates based on total volatile solids: PS:FW=30:70, PS:FW=50:50, PS:FW=70:30 y (PS+TSS):FW=70:30. The maximum methane yield, 0,25LCH 4 /gVSadded, was obtained for the mixture PS:FW=30:70, showing a yield 32% higher than the one obtained in the mono-digestion of PS.

“…Previous studies have also shown that there are various mechanical treatments that have different effects on the physical characteristics of the substrates (Izumi et al, 2010). The common action is that mechanical pre-treatments reduce particle size, thus increasing contact between the substrate and microorganisms and increasing the hydrolisis rate, which will in turn decrease COD and increase methane production (MataAlvarez et al, 2014;Esposito et al, 2012;Jain et al, 2015). From all the possible options, mechanical methods using chopping to reduce particle size appear to be the most readily available method for developing countries such as Indonesia, as it is also used as pre-treatment for composting.…”

The performance of anaerobic digestion (AD) to process organic fraction of municipal solid waste (OFMSW) can be improved with various pre-treatments. Mechanical pre-treatments, mainly chopping, have shown to be the most economical and relatively effective method to increase contact between the substrate and microorganisms. The purpose of this research was to analyze the effect of OFMSW particle size on CH 4 gas formation in a laboratory-scale Biochemical Methane Potential (BMP) assay. The research was conducted for 35 days at a temperature of 35°C with three sizes of OFMSW co-digested with cow manure. OFMSW with particle sizes of 1013 mm, 4.7610 mm, and 24.76 mm produce CH 4 gas with an average of 114.7+14.7 ml, 101.7+0.5 ml, and 110.9+10.8 ml, respectively, while methane yield was 0.277 L CH 4 /g VS, 0.208 L CH 4 /g VS, and 0.229 L CH 4 /g VS, respectively. Particle size is more likely to have an influence on the hydrolysis and acidogenesis processes, as demonstrated by the significant difference of VFA value, but not on the biogas potential. Particle sizes of 1315 mm produce 19.25 mg VFA/L, while the size range of 24.76 mm produces 118.1 mg VFA/L.
