2. Estimativa do potencial de recuperação energética de resíduos sólidos urbanos usando modelos matemáticos de biodigestão anaeróbia e incineração
RESUMO Atualmente, um dos grandes problemas enfrentados pelos gestores de resíduos sólidos urbanos (RSU) é a disposição final dos resíduos gerados por sua população. As disposições de resíduos devem ser feitas em espaços e sob condições adequados de modo a minimizar os impactos socioeconômicos e ambientais. Nesse contexto, este artigo teve por

3. AVALIAÇÃO DA PRODUÇÃO DE HIDROGÊNIO A PARTIR DA CODIGESTÃO ANAERÓBIA DE RESÍDUOS SÓLIDOS ORGÂNICOS E GLICEROL RESIDUAL DA PRODUÇÃO DE BIODIESEL
The anaerobic co-digestion of solid organic waste with residual glycerol from biodiesel production (1% v v-1) for hydrogen production was investigated by means of the Biochemical Hydrogen Potential (BHP). The specific hydrogen production from co-digestion with and without glycerol corresponded to 140 mL H2 g VS-1 and 87,3 mL H2 g VS-1 removed, respectively,

4. Crude glycerin in anaerobic co-digestion of dairy cattle manure increases methane production
ABSTRACT Anaerobic digestion of crude glycerin (CG) along with animal waste has been an excellent option for increasing the production of biogas and methane to achieve efficiency in the treatment of both residues. This study aimed to evaluate improvements in specific productions of biogas and methane, reductions in solid and fibrous components in substrates

5. ANAEROBIC DIGESTION OF MUNICIPAL BIOWASTE FOR THE PRODUCTION OF RENEWABLE ENERGY: EFFECT OF PARTICLE SIZE
Abstract In recent years, Anaerobic Digestion (AD) has become an important technological alternative for the management of municipal biowaste (MBW) for both pollution control and obtaining renewable energy such as methane. One of the factors that most affects the AD of MBW is the particle size, particularly in the hydrolysis and lag phases, this last being i

6. The Addition of Hatchery Liquid Waste to Dairy Manure Improves Anaerobic Digestion
ABSTRACT The objective of this study was to determine the optimal inclusion level of liquid egg hatchery waste for the anaerobic co-digestion of dairy cattle manure. A completely randomized experimental was applied, with seven treatments (liquid hatchery waste to cattle manure ratios of0: 100, 5:95, 10:90, 15:85, 20:80, 25:75 and 30:70), with five replicates

7. Methane production in anaerobic digestion of organic waste from Recife (Brazil) landfill: evaluation in refuse of diferent ages
This work focuses on monitoring the generation of biogas by biochemical methane potential (BMP) assays, commonly used to assess anaerobic biodegradability of solid and liquid wastes under controlled conditions. The experiment employed 5 g of substrate of both refuses (fresh and one-year-old wastes), digested with 250 mL of inoculum in 1 L flasks as bioreacto

8. Potential of biogas and methane production from anaerobic digestion of poultry slaughterhouse effluent
The objective of this study was to evaluate the efficiency of anaerobic digestion on the treatment of effluent from poultry slaughterhouse. The experiment was conducted at the Laboratory of Waste Recycling from Animal Production/FCA/UFGD. During four weeks, eight experimental digesters, semi-continuous models, were loaded and set according to the hydraulic r

9. Produção de biogás a partir de glicerol oriundo de biodiesel / Biogas production from glycerol generated on biodiesel industry
The Brazilian legislation demands the use of biodiesel mixed with diesel in an increasing rate. This raise on biodiesel production implies also on an increase on generation of glycerol, which is a liquid or semi-solid waste with high concentration of salts (approximately 46.1 g\ CL POT.-\ /L) and organic matter (1260 gCOD/L in average). Despite being widely

10. Generation of methane due to anaerobic digestion of municipal solid waste -a case study of the Metropolitan Center Landfill, Salvador - BA. / Geração de metano devido à digestão anaeróbia de resíduos sólidos urbanos - estudo de caso do Aterro Sanitário Metropolitano Centro, Salvador - BA .
Os Resíduos Sólidos Urbanos (RSU) decompostos anaerobiamente em aterros sanitários são responsáveis por grande parte das emissões de metano (CH4), um dos gases causadores do aquecimento global. Nos aterros sanitários os RSU ficam sujeitos ao processo de digestão anaeróbia tendo como produtos finais biogás, lixiviado e matéria orgânica estabilizad

11. Avaliação de diferentes inóculos na digestão anaeróbia da fração orgânica de resíduos sólidos domésticos
The process of anaerobic digestion of organic solid wastes can be optimized and accelerated by using methods that contribute to achieve a rapid and balanced start-up, such as the use of appropriate inocula. In this context, the present study aimed to analyze the potential application of bovine manure, pig manure and bovine rumen as inocula for the anaerobic

12. Characterization and treatment of sludge originated from septic tanks / Caracterização e pré-tratamento de lodo de fossas e de tanques sépticos
Septic tanks are small structures used for partial treatment of wastewater produced from urban and rural areas. It utilization is justify mainly by simplicity of construction and for being a technology that requires low operational dedication. Although it is a technology vastly used in Brazil, there is not much information about the characteristics of the wa
