Biomass is responsible for 25% of the primary energy supply in Brazil. However, future biomass demand will be influenced by many factors. This study evaluates potential pathways for the utilization of biomass in Brazil until 2050, while considering novel biobased sectors (renewable jet fuel and biochemicals), resource competition, and greenhouse gas (GHG) emissions. Whereas other least‐cost optimization models assess biobased options to meet energy and chemicals demand in Brazil to a limited extent, this study provides a detailed breakdown of biomass feedstock, including an extensive portfolio of biomass conversion technologies. A least‐cost optimization model is used to assess the demand for energy and chemicals, and the competition between biomass and other climate‐mitigation measures such as renewable power generation technologies, carbon capture and storage (CCS), and energy efficiency. Varied over the three scenarios, 86–96% of the sustainable biomass supply potential is used. Under more stringent mitigation targets, novel biomass conversion technologies start to play an important role: Biobased electricity production with CCS, jet fuel production from lignocellulosic biomass, and chemicals are partly produced from ethanol and bio‐naphtha. The modeling framework provides a transparent view of which type of biomass can be used for which specific purpose. It is therefore an interesting tool for future research, for example to examine the dynamic interaction with demand for land. © 2019 The Authors.

“…The SGBPTC incentive was originally expired on 31 December 2016, but it was retroactively extended through 31 December 2017; in this study, it is assumed that it will be effective throughout the whole lifetime of the projects. The SGBPTC law diminishes the producer's income tax liability by $0.267 for every litre of cellulosic biofuel manufacture for use in the United States . The impact of the incentive on the NPV was investigated for each case study in a two‐way fashion for calculating the biojet fuel revenue flows: first, by considering the computed MJSP and, secondly, the market price.…”

Summary The aviation industry continues to grow, and consequently, more fuel is needed. With the intention of decarbonising the aviation sector, sustainable routes that have the potential to mitigate emissions, such as biomass fast pyrolysis, can positively contribute to this direction. Within this context, the present study performs a comparative techno‐economic evaluation of aviation biofuel manufacture via the main bio‐oil upgrading pathways, namely, hydroprocessing (HP), gasification followed by Fischer‐Tropsch synthesis (G+FT), and zeolite cracking (ZC). The research constitutes the first endeavour to investigate and compare the feasibility of producing biojet fuel via pyrolysis‐based routes. The presented work provides an inclusive evaluation that comprises process modelling and financial assessment. Based on the simulations, overall energy efficiencies of 48.8%, 45.73%, and 45.38% and jet fuel energy efficiencies of 23.70%, 21.45%, and 20.53% were calculated, while the implementation of a discounted cash flow analysis estimated minimum jet fuel selling prices (MJSPs) of 1.98, 2.32, and 2.21 $/L for the HP, the G+FT, and the ZC, respectively. Sensitivity analysis revealed that the processes are capital and feedstock intensive while an increase to the bio‐oil yield will favour the economic performance of the examined biorefineries. An increase of the plant size from 100 (base case) to 150 dry tonnes per hour of feedstock will decrease the selling prices by approximately 25% for all cases. Monte Carlo simulations exhibited that without establishing and/or maintaining appropriate policy schemes, there is no pragmatic prospect for the examined biorefineries to beat the competition against the prevailing oil infrastructures.

“…Sugarcane cultivation is experiencing rapid growth throughout Brazil. The planted area has substantially increased to meet the ethanol demand of large economies that are interested in renewable fuels (Brinkman et al, 2018). In recent years, plant breeding programs have contributed to the development of the sugarcane crop in Brazil, by developing new cultivars that have an improved yield and quality (Dal-Bianco et al, 2012).…”

Sugarcane crops are grown in almost all regions of Brazil, in various types of soil and under the influence of different climate conditions, which results in diverse production environments as climate factors directly influence the yield and technological quality of a sugarcane crop. The present study evaluated the agronomic and technological characteristics of sugarcane cultivars grown in Af climate conditions. The agronomic traits (natural matter production and the number, length, and diameter of stalks) and technological attributes (Brix, purity, Pol, reducing sugars, total reducing sugars, moisture, and fiber content) of three sugarcane cultivars, IACSP93-6006, RB83-5486, and SP79-1011, were determined in a three-year experiment with a randomized block design using four blocks and two repetitions per block. The cultivars IACSP93-6006 and SP79-1011 exhibited superior agronomic traits compared to RB83-5486, showing better adaptation to the soil and climate conditions of the study area. However, the technological attributes, which were below the minimum standard levels required by the sugar and ethanol industry, were not statistically different among the studied cultivars. The abundant rainfall and high temperatures, characteristics of an Af climate, were not favorable for sucrose accumulation in the IACSP93-6006, RB83-5486, and SP79-1011 cultivars. Therefore, despite the high yield, sugarcane intended for industrial purposes should not be grown under Af climate conditions, owing to the insufficient technological parameters. ResumoA cana-de-açúcar é cultivada em quase todas as regiões do Brasil, em vários tipos de solo e sob a influência de diferentes condições climáticas, resultando em diversos ambientes de produção, sendo que fatores climáticos influenciam diretamente na produtividade e na qualidade tecnológica da canade-açúcar. Objetivou-se avaliar as características agronômicas e tecnológicas de cultivares de canade-açúcar cultivadas em condições climáticas tipo Af. Foram utilizadas três cultivares de cana-deaçúcar: IACSP93-6006, RB83-5486 e SP79-1011. O experimento foi realizado em delineamento em blocos casualizados, com quatro blocos e duas repetições por bloco. Na avaliação agronômica foram determinados a produção de matéria natural, número de colmos, comprimento do colmo e o diâmetro Semina: Ciências Agrárias, Londrina, v. 41, n. 1, p. 73-82, jan./fev. 2020 Miranda, A.
