“…Por fim, a metanogênese, última etapa do processo, é responsável pela transformação de todos os compostos formados anteriormente em metano (KASINATH et al, 2021). Não obstante, para a produção de biogás ser satisfatória faz-se necessário o estabelecimento de uma condição ideal de certos parâmetros (ausência de oxigênio, composição do substrato, temperatura e pH do meio) com o objetivo de elevar a atividade e crescimento dos principais microrganismos presentes no processo (WU et al, 2021). De uma maneira geral, os principais componentes presentes no biogás são Metano (CH4) e Dióxido de carbono (CO2).…”

A dependência global em relação aos combustíveis fósseis como fonte de energia vem gerando preocupações diante dos elevados índices de poluição ambiental e sua característica não renovável. Fontes alternativas renováveis e promissoras de energia, como o biogás, têm sido amplamente estudadas e discutidas na busca de um futuro mais sustentável. Este trabalho revisa as perspectivas de produção dos biocombustíveis, com foco especial no biogás. O presente estudo é então, um trabalho de revisão que busca definições que esclarecem sobre os processos de produção de biogás, esclarecendo quais as matérias-primas podem ser utilizadas, bem como sua composição e utilizações no mercado. Conforme apresentado nesta revisão, o biogás apresenta-se como uma alternativa viável de energia renovável e sustentável para a crescente demanda mundial por energia, encontrando-se em constante expansão de produção. Ainda, essa revisão salienta que a aplicação de tecnologias para purificação do biogás permite a utilização deste biocombustível como fonte energética de excelente qualidade oportunizando a redução do consumo de gás natural, minimizando a dependência dos combustíveis fósseis, contribuindo para o balanço energético global e reduzindo significativamente as emissões dos gases de efeito estufa.

“…The main factors influencing biogas production are feed sludge quality, feeding patterns and rates, operating temperature, pH/alkalinity in the digester, mixing intensity, and operating retention time. It is well known that anaerobic digestion process stability and optimization is dependent on these operational parameters (Wu et al, 2021). A summary of example cases of process instability due to operational aspects and countermeasures are reviewed by Wu et al (2021).…”

The water sector is in the middle of a paradigm shift from focusing on treatment and meeting discharge permit limits to integrated operation that also enables a circular water economy via water reuse, resource recovery, and system level planning and operation. While the sector has gone through different stages of such revolution, from improving energy efficiency to recovering renewable energy and resources, when it comes to the next step of achieving carbon neutrality or negative emission, it falls behind other infrastructure sectors such as energy and transportation. The water sector carries tremendous potential to decarbonize, from technological advancements, to operational optimization, to policy and behavioural changes. This book aims to fill an important gap for different stakeholders to gain knowledge and skills in this area and equip the water community to further decarbonize the industry and build a carbon-free society and economy. The book goes beyond technology overviews, rather it aims to provide a system level blueprint for decarbonization. It can be a reference book and textbook for graduate students, researchers, practitioners, consultants and policy makers, and it will provide practical guidance for stakeholders to analyse and implement decarbonization measures in their professions.

“…In the quest to reduce waste and produce energy, the anaerobic digestion (AD) process plays an important role [1,2]. AD is a very complex process, including hydrolysis, acidogenesis, acetogenesis, and methanogenesis, where the activity of various types of microorganisms in an oxygen-free environment degrades carbohydrates, lipids, and proteins from organic wastes into biogas [3,4].…”

Anaerobic digestion (AD) is a promising technology for renewable energy production from organic waste. In order to maximize the produced biogas quantity and quality, this paper deals with the optimization of the AD process in a CSTR bioreactor of a full-scale biogas plant. For this purpose, a novel approach was adopted coupling, a highly complex BioModel for AD simulation, and a gradient-based optimization method. In order to improve AD performance, the dosages of various types of biological additives, the dosages of inorganic additives, and the temperature in the bioreactor were optimized in three different scenarios. The best biogas quality was obtained using multi-objective optimization, where the objective function involves the following two conflicting objectives: the maximization of biogas production and minimization of the needed heating energy. The obtained results show that, potentially, the content of CH4 can be increased by 11%, while the contents of H2, H2S, and NH3 can be reduced by 30%, 20%, and 81% when comparing the simulation results with the experimental data. The obtained results confirm the usefulness of the proposed approach, which can easily be adapted or upgraded for other bioreactor types.
