The EU aims to achieve a variety of ambitious climate change mitigation and sustainable development goals by 2030. To deliver on this aim, the European Commission (EC) launched the bioeconomy strategy in 2012. At the heart of this policy is the concept of the sustainable Biorefinery, which is based centrally on a cost-effective conversion of lignocellulosic biomass into bioenergy and bioproducts. The first generation of biorefineries was based on utilization of edible food crops, which raised a "food vs. fuel" debate and questionable sustainability issues. To overcome this, lignocellulosic feedstock options currently being pursued range from non-food crops to agroforestry residues and wastes. Notwithstanding this, advanced biorefining is still an emerging sector, with unanswered questions relating to the choice of feedstocks, cost-effective lignocellulosic pretreatment, and identification of viable end products that will lead to sustainable development of this industry. Therefore, this review aims to provide a critical update on the possible future directions of this sector, with an emphasis on its role in the future European bioeconomy, against a background of global developments.

“…Succinic, lactic, and itaconic acids are examples of precursors of polymer synthesis that can replace petrochemical‐based products . Organic acids can be produced by the fermentation of sugars, such as glucose, xylose, and sucrose . Thus, the use of the hydrolyzed broth of lignocellulosic residues can reduce the industrial processing cost.…”

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

“…18 Desse modo, vale salientar que a produção de combustíveis obtidos a partir de biomassa lignocelulósica vem crescendo devido ao fato de vários tipos dessas biomassas estarem presentes, em grande quantidade, em quase todas as regiões do planeta, sendo a maioria representada por resíduos agroindustriais. 19 Nesse sentido, o presente trabalho teve como objetivo avaliar a eficiência do pré-tratamento do bagaço de cana-de-açúcar por explosão a vapor em reator autoclave por meio de caracterização química e análise morfológica.…”

Biofuels industries have made great efforts to establish the best pretreatment of lignocellulosic biomass for 2G-ethanol production. Therefore, this work, sugarcane bagasse (BCA), employed to the pre-treatment of steam explosion in an autoclave reactor at 120 °C. The chemical characterization performed by high performance liquid chromatography and morphological analyzes by spectroscopic techniques (FTIR and XRD). The evaluated pretreatment revealed changes in chemical and structural composition biomass with cellulose mass percentage of 37.51 and hemicellulose 21.32 in the untreated BCA for 30.82 cellulose and 17.14 of hemicellulose in the pre-treated BCA. The fractions cellulose and hemicelluloses decreased after pretreatment, suggesting generation other products as furfural, hydroxymethylfurfural, acetic acid and formic acid. The FTIR and XRD spectroscopy analyzes showed structural differences between the complexity of the untreated and pretreated biomass. Therefore, the results suggest that the pretreatment results in the breakdown of the biomass fibers. As indústrias de biocombustíveis têm empenhado grande esforço para estabelecer o melhor prétratamento da biomassa lignocelulósica para produção de etanol de segunda geração. Portanto, neste trabalho, o bagaço da cana-de-açúcar (BCA), foi submetido ao pré-tratamento de explosão a vapor em reator autoclave a 120 °C por 45 min. A caracterização química foi realizada por cromatografia líquida de alta eficiência e as análises morfológicas por técnicas espectroscópicas (FTIR e DRX). O pré-tratamento avaliado revelou mudanças na composição química e estrutural da biomassa com porcentagem mássica de celulose de 37,51 e hemiceluloses 21,32 no BCA não tratado para 30,82 de celulose e 17,14 de hemiceluloses no BCA pré-tratado. As frações de celulose e hemiceluloses diminuíram após o pré-tratamento, produzindo outros produtos como furfural, hidroximetilfurfural, ácido acético e ácido fórmico. As análises por espectroscopia FTIR e DRX indicaram diferenças estruturais entre a complexidade da biomassa não tratada e pré-tratada. Portanto, os resultados indicam que o pré-tratamento resulta em desorganização das fibras que constituem a biomassa.
