“…The current high atmospheric concentrations of carbon dioxide must be considered as a consequence of the anthropogenic emissions due to fossil fuels. Transportation fuels comprise about 13% of global emissions of anthropogenic Since the amount of published research documents about hemicellulose valorization which are available after a bibliographic search is huge (some review papers that considered the valorization of biomass represent great examples [20][21][22][23][24]), basic managing tools are needed to handle all this information. Bibliometrics is a useful tool to map the literature around a research field.…”

A bibliometric analysis of the Scopus database was carried out to identify the research trends related to hemicellulose valorization from 2000 to 2016. The results from the analysis revealed an increasing number of annual publications, a high degree of transdisciplinary collaboration and prolific contributions by European researchers on this topic. The importance of a holistic approach to consider the simultaneous valorization of the three main components of lignocellulosic biomass (cellulose, hemicellulose and lignin) must be highlighted. Optimal pretreatment processes are critical for the correct fractionation of the biomass and the subsequent valorization. On the one hand, biological conversion of sugars derived from hemicellulose can be employed for the production of biofuel (ethanol) or chemicals such as 2,3-butadiene, xylitol and lactic acid. On the other hand, the chemical transformation of these sugars produces furfural, 5-hydroxyfurfural and levulinic acid, which must be considered very important starting blocks for the synthesis of organic derivatives.

“…According to all global assessments, biomass will be pivotal for decarbonizing our economy . An advantage of this resource over other renewable options is that it can be converted into a wide array of energy carriers and into chemicals, thereby providing a substitute for the role of fossil feedstocks in the petrochemical sector . Lignocellulosic biomass, in particular – woody material, straw, and other non‐digestible feedstocks composed of (hemi)cellulose and lignin – is the focus of attention as this is abundantly available in the form of residues and is less susceptible to sustainability issues than cultivated agricultural crops used for bioenergy .…”

Lignocellulosic biomass is expected to play an important role in decarbonizing our economy. In this modeling study, we assessed the future role of biobased chemicals and energy from this resource in the EU up to 2030. The study's general outcomes indicate that biobased heat remains the largest biobased sector over this period, and biobased chemicals remain the smallest. A significant share of EU‐domestic lignocellulosic biomass potential remains unutilized, even when feedstock availability is restricted. The technology mix for biobased heat, power, biofuels, and chemicals remains relatively stable in all cases, with a strong role for biobased combined heat and power (CHP). Several specific ‘what if’ analyses were done. These show that both restriction of feedstock potential and active mobilization of available potential affect overall costs of biobased options, illustrating the relevance of specific policies in bringing biomass potentials to the market. In feedstock‐restricted scenarios, specific attention to advanced lignocellulose‐based fuel technologies is essential to meet biofuel ambitions. Another analysis indicates that both competition and synergy effects occur between energy and chemical applications of biomass. This illustrates that biorefining and co‐production of biobased chemicals and energy in integrated biorefineries is a better and more robust business than separated production. Finally, an analysis of the dynamics between lignocellulosic and crop‐based biofuels reveals that the current capacity of the latter creates a need for a specific subtarget for lignocellulose‐based biofuels before they can enter the market, and that crop‐based biofuels may be gradually phased out, but with significant additional costs. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd

“…One advantage of this biopolymer is that it displays some characteristics of fossil‐based polymers, such as low gas permeability and high crystallinity . The commercial production of PHB and other PHAs is not yet significant and this is most likely due to the production costs still not being competitive . Currently, Pedra mill (Serrana, SP, Brazil) has a demonstration plant for the production of PHB with a production capacity of 50 t of PHB per year.…”

Process integration is an interesting option to reduce costs and improve the economic viability of new processes in sugarcane mills. Brazil has a prolific sugar‐energy sector, with hundreds of sugarcane mills that could possibly act as sources of carbon, energy, and water for annexed plants. While many studies analyze the integration of new technologies into sugarcane biorefineries as greenfield plants, the assessment and establishment of integrated processes into existing plants will help detecting process bottlenecks and enabling the required levels of integration to be better understood prior to designing a full‐scale, greenfield biorefinery. The present review provides an overview of the possibilities for sugarcane mills to diversify the portfolio of products from sugarcane biomass – beyond ethanol, sugar, and electric energy. The work initially considers the integrated production of market‐ready sugarcane‐derived products, such as animal feed, industrial salts, and hydrocarbons in existing Brazilian plants. Finally, the study outlines the prospects for future integration of non‐traditional process alternatives in sugarcane mills, namely bioplastics, organic acids, molecular hydrogen, and advanced lignocellulosic compounds. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
