| This research aims to evaluate performance of a water hyacinth (Eichornia crassipes (Mart) Solms) pond used to treat biogas effluent of a tapioca industry wastewater treatment system. The water hyacinth pond which treats biogas effluent has been monitored for about two months. Wastewater samples were taken from influent and effluent of the water hyacinth pond. Parameters to be observed included wastewater quality parameters (pH, temperature, turbidity, BOD5, ammonia, solids, evapotranspiration, discharge, and hydraulic retention time) and water hyacinth parameters (growth, population density, moisture, ash, nutrient contents). The results showed that water hyacinth improved some parameters of the biogas effluent to some extent. Within HRT of 53 days,... |

| ABSTRACT The global use of fossil energy sources has led to the need to develop technologies capable of mitigating its consequences. One such option is anaerobic biodigestion, which is already scientifically well-established, although the use of its main products (biogas and biomethane) still requires further development before they can be employed in automotive vehicles, largely due to technical issues concerning their storage. The storage of methane using adsorption (Adsorbed Natural Gas - ANG) is a technology that requires less energy and moderate pressures and temperatures. However, the main storage techniques continue to be those that involve high pressures and/or cryogenic temperatures. The present work evaluates the performance of an unprecedented... |

| ABSTRACT Sewage sludge is a solid waste composed of water, rich in organic matter and nutrients, but concentrator of pathogenic microorganisms. Its use as agricultural fertilizer in the state of Paraná, Brazil is common. However, it is necessary to eliminate or significantly reduce microorganisms by means of a hygiene process. This can be obtained thermally, requiring a source of energy for heat generation. In this sense, a pilot system was constructed consisting of a stainless steel radiant floor, capable of transferring heat to the sewage sludge from coils coupled in base, through which the heated water circulates. The energy comes from solar radiation and is complemented by biogas from the anaerobic sewage treatment. Aiming to investigate the system's... |

| Abstract Animal biomass is a source of energy commonly discarded without or with low utilization, but its availability draws attention to its reuse [1]. The utilization can be carried out in different ways, varying in terms of generation time and efficiency. The use of biodigestion requires a relatively small area compared to landfills or natural composting, and it provides other materials besides biogas, that can be recycled as fertilizer and has a short residence time of residues [2]. The energy supplied as biogas can be harnessed as heat or electricity in case of conversion. Considering the energy needs of animal husbandry and the ease of reinsertion of energy in the production cycle, the possibility of distributed generation of biogas was studied as a... |

| Abstract Advances in energy demand in rural areas cannot be dissociated from agricultural modernization, large estates, mechanization of labor and reduced investment in small production. The use of biogas together with biomass are the most cost-effective ways for the small producer, as it has a high calorific value. In the case of biogas the procedure is performed by combining a compressor and a chiller, allowing the gas enter the reactor and burn together with the air stream. The use of these techniques is an auxiliary way to reduce the cost of the producer to produce a certain crop, besides allowing a participation in the final energy supply, so that the utilities have an alternative to distribute the surplus energy to another region, serving thus a... |

| This review provides a summary of the research conducted on the use of crude glycerol, the major byproduct of the biodiesel industry, as substrate for anaerobic co-digestion and production of biogas. In general, for every 100 kg biodiesel produced, approximately 10 kg crude glycerol is generated. Because this glycerol is expensive to purify for use in food, pharmaceutical, or cosmetic industries, biodiesel producers must seek alternative methods for its disposal. Several studies have demonstrated that the use of crude glycerol as a C source for fermentation and biogas generation is a promising alternative use for this waste material. The high C content of glycerol increases the C:N ratio in the mixture, avoiding the inhibition of the process by the excess... |

| A two-phase anaerobic biodigestor was employed in order to analyze methane production with different manipueira organic loading rates. The acidogenic phase was carried out in a batch process whereas the methanogenic in an up-flow anaerobic fixed bed reactor with continuous feeding. The organic loading rates varied from 0.33 up to 8.48g of Chemical Demand Oxygen (COD)/L.day. The highest content of methane, 80.9%, was obtained with organic loading rate of 0.33g and the lowest, 56.8%, with 8.48gCOD/L.d. The highest reduction of COD, 88.89%, was obtained with organic loading rate of 2.25g and the lowest, 54.95%, with 8.48gCOD/L.d. From these data it was possible to realize that anaerobic biodigestion can be managed in at least two ways, i.e., for energy... |

| Se realizaron tres experimentos en biorreactores acoplados a trampas de gas para evaluar el efecto de Saccharomyces cerevisiae y fumarato de sodio en la fermentación in vitro de alfalfa. En el primero se evaluó la fermentación de alfalfa en medio de cultivo glucosa, celobiosa, almidón y fluido ruminal (GCAFR) usando trampas de gas con agua, solución salina ácida y solución de NaOH. Se midió producción de biogás, CH4, CO2, pH y bacterias totales (BT). El diseño experimental fue completamente al zar con arreglo factorial 2 x 3, y tres repeticiones por tratamiento. En el segundo experimento se evaluó el efecto de Yea sacc®, Procreatin 7® y Diamond V XP® en la fermentación in vitro de alfalfa. Se midió producción de CH4, ácidos grasos volátiles (AGV),... |

| Las emisiones de metano (CH4) de las actividades ganaderas, como un gas de efecto invernadero, son estimadas para el desarrollo de inventarios. Sin embargo el aprovechamiento de la producción del CH4 a partir de excretas de animales rumiantes y no rumiantes, para la generación de energía, requiere de establecer condiciones de temperatura y humedad para eficientar la mayor producción de este gas, compuesto del biogás producido por la actividad microbiana. En este estudio, se desarrollaron cuatro experimentos para cuantificar la producción de CH4, con la fermentación controlada, en un sistema biorreactor-trampa. En el 1er experimento, se compararon diferentes excretas de animales rumiantes: estiércol de ganado lechero y en engorda, excretas de cabras y... |
