“…Other studies have been carried out on the effect of chemical pretreatment on constituent extraction in biomass. In one report, Carvalho et al [46] used cold alkaline extraction for bioethanol production from eucalyptus, sugarcane bagasse and sugarcane straw. They found that the pretreatment removed 46 %, 52 % and 61 % of the xylan and 15 %, 37 % and 45 % of the lignin for eucalyptus, bagasse and straw, respectively.…”

Biocomposite materials manufactured from natural fibres and polymer matrix represent a group of engineered composite products with diverse applications. These materials continue to find increasing applications due to their design flexibility, superior properties and aesthetic appeal. The applicability of these biocomposites, however, depends on the interaction in the fibre-matrix interface. This paper reviews the state of the art research in fibre-matrix interfacial interaction based on published literature. A brief background on biocomposite materials is presented. The focus of this review is the modification of natural fibres and its effect on fibre-matrix interfacial adhesion and properties. In addition, the effect of chemical treatment on fibre composition and fibre-matrix interfacial bonding mechanism are discussed.

“…A conclusão foi que estas condições de pré-tratamento são benéficas para a seguinte etapa de sacarificação (processo de hidrólise em que o amido é transformado em açúcares fermentáveis) já que a celulose fica mais disponível, contribuindo desta forma para aumentar os rendimentos da produção do bioetanol. Carvalho et al (2016) realizaram uma abordagem matemática para otimizar o processo de extração a frio como prétratamento para produção de bioetanol a partir de eucalipto, bagaço e palha de cana-de-açúcar. As condições ideais foram identificadas com base em um experimento com delineamento fatorial resultando na remoção de 52% e 61% de xilano e 37% e 45% de lignina para o bagaço e a palha da cana respectivamente.…”

O Brasil é o maior produtor mundial de cana-de-açúcar, sendo assim o objetivo deste trabalho foi apresentar os impactos econômicos, sociais e ambientais do seu cultivo além de mostrar algumas aplicações dos subprodutos gerados no processo de produção com enfoque na sustentabilidade do setor. Para tanto, a metodologia utilizada foi a revisão da literatura disponível em quatro bases de dados: Scielo, CAPES, Science Direct e Google Scholar sobre o tema. Percebe-se que a indústria sucroalcooleira produz um impacto tanto no setor econômico, social e ambiental. Os subprodutos oriundos do processamento quando bem utilizados podem promover lucros, diminuição dos problemas ambientais e geração de emprego e renda. Porém, é necessário grande investimento tanto do setor público e privado em tecnologias e pesquisas acadêmicas, pois, a utilização dos subprodutos é altamente promissora para o desenvolvimento sustentável permitindo a correta destinação dos resíduos gerados, conduzindo ao caminho promissor do desenvolvimento sustentável.

“…However, other crops are also prominent, such as wheat, cassava, rice, banana, and oil palm. Processing these crops generates large amounts of solid residues, including in‐field or agricultural residues (straw, leaves, and foliage) and agro‐industrial processing residues (bagasse, bunches, and shells) with diverse composition and volume (Table ) …”

South America is a pivotal supplier of agricultural commodities for a growing world population. This large-scale production generates a substantial amount of lignocellulosic residue. Inadequate disposal of this material can lead to putrefaction and leaching, and can attract insects and rodents. Solid residues can be treated by incineration or composting -both causing greenhouse gas emissions. Biotransformation of lignocellulosic residues into valuable products has been proposed as a more sophisticated alternative to burning. However, pretreatment steps are necessary to obtain fermentable sugars for biological or thermochemical transformation into value-added products. In this review, we noted trends in lignocellulosic biomass generation and potential uses, with special attention to the procedures necessary for the generation of fermented products and bio-oil. This survey pointed out that sugarcane bagasse, cereal straws, bananas, and oil-palm biomass can generate about 900 million tonnes of biomass by 2025. Based on production data from several researchers it was estimated that these raw materials have the potential for annual production of more than 550 million tonnes of fermentable sugars (i.e., glucose and xylose), 670 million tonnes of bio-oil, or 4000 TWh of thermal energy. We describe procedures and strategies for the conversion of these residues to produce higher value-added biomolecules and to promote more sustainable application of lignocellulosic biomass
