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).…”

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.

“…It is required to improve biomass characteristics in order to enhance their efficient utilization for production of high-value bioproducts (Anukam & Berghel, 2021;Anukam et al, 2016;Chiang et al, 2012). The main goal of biomass pre-treatment is to facilitate microbial digestion by removing barriers and making the organic content of the substrate easily accessible and usable for producing high-value bioproducts (Kasinath et al, 2021). Thus, complex organic matter (e.g., cellulose, hemicellulose, and lignin, proteins, polysaccharides and lipids) need to be solubilized and hydrolysed into simple components such as long-chain fatty acids, sugars and alcohols (Kasinath et al, 2021;Zhen et al, 2017).…”

The value chain (VC) system is a key way to address important sanitation technological and institutional gaps in production and service delivery and could constitute a natural platform for development actions and also serve as a market systems approach to improve access to safely-managed sanitation. It has been suggested that sanitation could boost local and national economies and global interconnections with a growing recognition that the private sector can play a bigger role in delivering the Sustainable Development Goal for sanitation, and help businesses understand value-added and product opportunities. This book proposes a pathway towards re-thinking the sanitation value chain (SVC) and suggests that it should cover all processes, activities and products of enterprises/actors in the sanitation supply chain that provide value-added services within each stage. Following the Regenerative Sanitation Principles, this book presents a new perspective to the SVC known as the ‘integrated functional sanitation value chain’ (IFSVC) to address operational functions within sanitation systems in combination with sanitation enterprises, operators and external actors that support the growth of the sanitation economy. The underlying premise of this book is that the IFSVC represents a new perspective that would have major social, environmental and economic implications for local, national, regional and global sanitation service delivery. It is hoped that researchers, business leaders, entrepreneurs, government officials and funders will find this book valuable, and be inspired and enabled to carry sanitation work forward in their own spheres of operation. The book gives several examples of encouraging developments, particularly in technical and business model innovation. It is our hope that this book will provide the stimulus for new learning and its application, particularly through cross-disciplinary and cross-sector partnerships that bring together all the skills and capabilities needed to deliver a fully effective IFSVC.

“…The selection of conditions for the process was developed on the basis of previously conducted studies using feed with similar physicochemical characteristics and on information from the literature on the disintegration process for various substrates [16]. To the best of author's knowledge, a temperature range of 45-55 • C and feed retention time can allow a beneficial solubilization degree to be obtained; dissolved oxygen concentration of 0.2 mg/dm 3 ensures aerobic condition of process; mixing intensity of 25 Hz ensures distribution of oxygen as well as heat.…”

Innovative low-temperature disintegration (process temperature 55 °C and oxygen concentration 0.2 mg/dm3) can be an economically rational technology to intensifying energy production from renewable sources. The proposed process can achieve a degree of disintegration—under optimal conditions—of about 50%, which is excellent when compared with other methods of feed pre-treatment. The low-temperature disintegration of distillation residue and waste-activated sludge before the co-fermentation process increased biogas production by 30% and methane production by 65% (over a 26 d duration). The obtained results confirm that the low-temperature disintegration method can be effectively used to pre-prepare this type of feed. At the same time, it was discovered that the Gompertz model can be used to mathematically describe the biogas accumulation curves in the methane co-fermentation processes of the tested feeds (the correlation coefficients were higher than 0.98).
