SUGARCANE BIOREFINERY TECHNOLOGY, AND PERSPECTIVES

Posted on Leave a comment on SUGARCANE BIOREFINERY TECHNOLOGY, AND PERSPECTIVES

In the context of the most cultivated agroenergy biomass in the world, sugarcane is one of the most ecological and sustainable, fundamental for the economy, reduction of carbon dioxide emissions, quality of life in urban centers and global improvement of the environment. It is not known for sure its origin, many believe that sugarcane was first cultivated in New Guinea, where it was considered a wild and ornamental plant.

Sugarcane consists of the stalk – formed by several culms, which are divided between each other and made up of fibers (cellulose, hemicelluloses and lignin) and sugar (sucrose, fructose and glucose) and leaves – composed of green leaves and dried leaves, also called straw. Regarding the sugarcane mass composition, the three main components (straw, bagasse and juice) are practically in the same proportions and together represent 43% of the plant mass content, the remaining 57% are represented by water. In energy terms, the same proportionality is verified among the sugarcane constituents, giving about 7,400 MJ of energy content.

Straw and bagasse are mostly used for a number of agronomic benefits for example: weed control, moisture retention, animal feed and improving soil physical, chemical and biological properties. However, due to the significant amount that is generated, its composition and, consequently, the chemical and energetic potential of the vegetable fiber, it is possible to use part of these materials in a more noble use, both chemically and energetically, without any damage to agronomic benefits through processes involving the different biorefinery platforms – chemical route, biochemical route and thermochemical route.

Thinking about this optimistic scenario, which involves the integral and sustainable use of sugarcane through the different biorefinery platforms, I happily announce the launch of my new book “Sugarcane Biorefinery, Technology and Perspectives”, ISSN 9780128142363, published by the prestigious Elsevier Publisher. The book provides the reader with a current overview of the global scenario of sugarcane biorefinery. It explores existing biorefinery platforms that can be used to convert sugarcane biomass into new value-added products. It also addresses one of today’s most controversial issues involving “energy cane” as well as the “sugar cane versus food versus environment” dilemma, adding even more value in a culture that is already a symbol of case study all around the world. Divided into 13 chapters, prepared by some of the leading authorities on each of the topics addressed, the work is an important contribution to the dissemination of knowledge and the consolidation of sugarcane biorefinery in the world. This book is essential for researchers, undergraduate and graduate students, professionals in the sugar and energy industry, as well as people interested in the field of sugarcane biorefinery. The future of biorefinery has begun!

BIORREFINARIA – A Nova Fronteira do Conhecimento Agrícola e Industrial

Posted on Tags , ,

O conceito de sustentabilidade, muito visado nos últimos anos, está ligado à substituição de fontes esgotáveis por fontes renováveis de energia. Neste caminho da sustentabilidade, se encaixa o conceito de biorrefinaria, que visa converter biomassa em biocombustíveis, bem como bioenergia e bioprodutos de interesse comercial, a fim de encontrar uma solução que combine viabilidade econômica com uma produção ambientalmente amigável.

O Brasil vem se destacando como um excelente empreendedor de agricultura agroenergética, principalmente, devido à diversificação de biomassas cultivadas, as condições edafoclimáticas favoráveis ao cultivo e a grande extensão territorial. Culturas como, algodão, arroz, banana, batata, café, cana-de-açúcar, eucalipto, milho, soja, trigo e outras, que são amplamente cultivadas no país, veem chamando atenção não apenas pela sua produtividade, como também na geração significativa de resíduos vegetais e industriais produzidos.

Esses resíduos (vegetais e industriais) são, em sua maioria, utilizados para uma série de benefícios agronômicos, por exemplo, na melhoria das propriedades físicas, químicas e biológicas do solo. Entretanto, em função da quantidade significativa de resíduos gerados e da composição da fibra vegetal, é possível utilizar parte desses resíduos em um aproveitamento mais nobre, tanto do ponto de vista químico quanto energético, sem que haja prejuízos aos benefícios agronômicos, através de processos de biorrefinaria.

De maneira geral, esses processos envolvem a (I) rota química – transesterificação química, hidroprocessamento, craqueamento catalítico, reações de Fischer-Tropsch etc; a (II) rota bioquímica – fermentação, digestão anaeróbica, transesterificação através de lípases para produção de biodiesel etc e; a (III) rota termoquímica – gaseificação, combustão, pirólise etc.

Trabalhos envolvendo processos de biorrefinaria ganham cada vez mais destaque com grande potencial de investimento, visto que buscam o aproveitamento sustentável da biomassa. Em outras palavras, a biorrefinaria utiliza o mesmo conceito da refinaria de petróleo, porém partindo de uma fonte renovável e tem sido identificado como a rota mais promissora para a criação de novas indústrias. Essa visão de desenvolvimento tecnológico terá grande relevância e importância no que tange a evolução dos setores agrícola e industrial, áreas prioritárias no Brasil, refletindo diretamente na geração de emprego e renda em diferentes segmentos da sociedade. Biorrefinaria – A Nova Fronteira do Conhecimento Agrícola e Industrial já começou!

BSS MAGAZINE – BIOREFINERY SUSTAINABLE SOLUTIONS

Posted on Leave a comment on BSS MAGAZINE – BIOREFINERY SUSTAINABLE SOLUTIONS

The concept of sustainability, which has been much sought in recent years, is linked to the substitution of exhaustible sources of energy for renewable sources. Into this way of sustainability fits the concept of biorefinery, which aims to convert biomass into biofuels as well as bioenergy and bioproducts of commercial interest, seeking to find a solution that combines economical viability with an environmentally friendly production.

Several countries have been standing out as a great entrepreneur of energy agriculture, mainly due to the diversification of cultivated biomasses and the edaphoclimatic conditions favorable to their cultivation. Crops such as cotton, rice, bananas, potatoes, coffee, sugarcane, eucalyptus, corn, soybeans, wheat, oats, coconuts and others have been drawing attention not only for their productivity, but also for the generation of vegetable and industrial residues produced.

These residues are mostly used for a number of agronomic benefits, for example, in controlling weeds, retaining moisture, improving the physical, chemical and biological properties of the soil. However, due to the significant amount of waste generated, its composition and, consequently, the chemical and energetic potential of the plant fiber, it is possible to use part of this waste in a more noble end, both from a chemical and an energetic point of view, without any damage to the agronomic benefits, through processes that involve the different biorefinery platforms – chemical, biochemical and thermochemical.

This concept of biorefinery has been gaining increasing prominence with great investment potential and has been identified as one of the most promising routes for the creation of new industries. This vision of technological development will have great relevance and importance in what concerns the evolution of the agricultural and industrial sectors of the world biomass, directly reflecting the generation of employment and income in different segments of society.

Thinking of this optimistic scenario, which involves the integral and sustainable use of biomass through the different biorefinery platforms, we decided to create BSS Magazine – Biorefinery Sustainable Solutions. The main objective is to contribute to the wide promotion and dissemination of research and technologies that guide the different routes of biorefinery on the world stage. There will be four editions per year and will be available free for reading and download in different countries and continents around the world. Our team is made up of professors and researchers recognized worldwide from different countries. The future of biorefinery has begun!
