“…Já na segunda etapa, conhecida como Acidogênese, as bactérias têm o papel de transformar os compostos advindos da primeira fase em ácidos gordos voláteis e/ou ainda em outros ácidos orgânicos (FRITSCH; HARTMEIER; CHANG, 2008). Na terceira fase, denominada de Acetogênese, as bactérias transformam os ácidos gerados na terceira fase em dióxido de carbono e acetato (ZHENG et al, 2009). Por fim, a última etapa do processo é a Metanogênese que compreende em converter o acetato e o dióxido de carbono em metano, surgindo então o biogás (CARNEIRO, 2013).…”

O presente artigo se propõe a revisar o tema de gerenciamento de dejetos suínos, em especial no que tange à conversão destes resíduos em biogás e energia, de forma a minimizar os impactos ambientais causados pela prática da suinocultura. Na contextualização geral é abordada a representatividade da cadeia produtiva no Brasil e no cenário internacional, além dos resíduos provenientes da pecuária. O enfoque é dado à geração de biogás, biofertilizantes e energia. Dessa forma, a revisão de literatura elenca os estudos correlacionados com a temática e suas contribuições para a área. Neste sentido se estabelece como objetivo revisar artigos dos principais autores internacionais e nacionais sobre o tema nos últimos cinco anos, no sentido de destacar aqueles de maior relevância para a pesquisa. Como resultado verificou-se através da pesquisa bibliográfica que o tratamento de dejetos suínos se torna cada vez mais uma necessidade em função dos seus impactos ambientais e da capacidade de conservação limitada do solo, do ar e da água, tendo em vista as demandas do setor no cenário atual. PALAVRAS-CHAVE:Dejetos suínos. Resíduos. Geração de Biogás.

“…VS and COD are strongly correlated with specific methane yield followed by pH, ammonium nitrogen, and total nitrogen. A previous study reported as total solid in substrate increases and that organic matter conversion by microorganism induced higher methane production [20]. R 2 indicates a slightly stronger relationship between Fig.…”

IntroductionToday, anaerobic digestion is widely applied to treat a diverse range of organic waste that promotes betterment in landfill management and produces a potential renewable energy source. Organic waste (mainly food waste) is very attractive and a potential feedstock for anaerobic digestion due to it high fraction in waste generation, especially in Malaysia. Moreover, the high composition of fat and lipids in organic waste contributes to higher conversion of organic matter in the waste fraction for biogas production. However, degradation of lipids and fats produces longPol. J. Environ. Stud. Vol. 25, No. 4 (2016), 1549-1554 AbstractThis paper describes a batch study on four different mixture ratios of household organic waste and cow manure. The biomethane potential test is used to evaluate the suitability of high solid anaerobic co-digestion of household organic waste and cow manure and its biodegradability. The maximum methane yield was observed for both co-digestions in R 3 (247 mL/g VS) and R 4 (244 mL/g VS). The percentages of mass recovery were 65-80% (based on VS removal). The biodegradability of each reactor was recorded as 97.7%, 10.7%,71.6% and 76.8% for R 1 , R 2 , R 3 , and R 4 , respectively. High solid co-digestion of household organic waste and cow manure in different mixture ratios increase the specific methane yields compared to mono-digestion. Hence, this clearly demonstrates a synergistic effect on the stability of anaerobic digestion. Upon correcting the results of the theoretical method with experimental data, an agreement ranged 70-90% was achieved.

“…In this method the organic biomass waste is degraded or biologically transformed by diverse microorganisms, and convert the biomass waste into biogas [53], [54]. The biofuels resulted from the anaerobic digestion can then be utilized as a replacement for fossil fuels, and as these products are carbon neutral so they reduce carbon dioxide emissions to the environment, this process involves four main stages, these are (1) Hydrolysis, (2) Acidogenesis, (3) Acetogenesis, and (4) Methanogenesis [109]. Figure-2 shows the complete process of anaerobic digestion [109].…”

-Lignocellulosic Biomass is considered to be the best option for biofuels production, due to the energy and food security concerns comparative to the use of other wastes, but this biomass has limited digestibility due to many factors like particle size, crystallinity of cellulose, lignin content etc. Pre-treatments enhance the digestibility by reducing the effect of these factors. Different pretreatment types exist, but now microwave pretreatment (individual or combined with other pretreatments) is becoming common due to its better results. This paper reviews the advantages of using lignocellulosic biomass in terms of the biofuels obtained from it, common pretreatments applied on it, and the effects of microwave pretreatments (individual and combined) over it.
