“…Since the 2007/2008 harvest, the projection of the agro-industrial production costs of the sugar-energy sector has been performed (Bigaton et al, 2015;Bigaton et al, 2016;Bigaton et al, 2017). The forecast of the total costs for the production of ethanol anhydride and hydrate of the 2015/2016, 2016/2017, and 2017/2018 crops of the Central-South region of Brazil was presented.…”

Interest in biofuels is growing, and ethanol has been the most used biofuel as an additive and as a gasoline substitute and, it is considered a potential alternative to traditional fuels. Ethanol represents 17% of energy consumption in transportation in Brazil, the transport sector's share in the energy matrix is 32.4%, which is the second most energy-consuming sector. The production of first and second-generation ethanol in the same industrial plant presents better financial results compared to the isolated processes. Also, ethanol obtained from the sugarcane has renewability, biodegradability and provides CO2 emissions mitigation. The objective of the work is to perform an analysis of the ethanol with several levels of hydration in terms of energetic, economic, environmental and safety. The results showed that each 10% of water in ethanol dilution the temperature in the flame surround decreases by 4%. Besides, the ethanol with 20% of water dilution emits 20% less radiation compared to 10% of water dilution. Indeed, the energy consumed in the distillation to produce ethanol with 10% of water is double. On the other hand, this energy difference in the production of ethanol diluted with 30% of water is not enough to compensate for the losses in the energy use process. Also, large amounts of water in ethanol dilution might be unfeasible the use due to the total cost of transportation. Therefore, ethanol with 20% of water represents the more efficient, cleaner and safe fuel in free flame applications.

“…A partir das projeções de custos de produção para a safra 2017/18, foram elaborados cenários 9 combinando as estimativas de produtividade agrícola da cana-deaçúcar e o preço do ATR ou dos produtos derivados da cana, assim como em Bigaton et al (2015). Os cenários otimista e pessimista representam variações positivas e negativas em relação à estimativa do cenário base.…”

Resumo Esta publicação apresenta as projeções de custos de produção agroindustriais do setor sucroenergético para a safra 2017/18 na região Centro-Sul do Brasil. Caracterizada pela queda de área colhida e produtividade, esta safra deverá apresentar elevação dos custos de produção totais dos açúcares e queda no custo de produção do etanol. O custo de cana-de-açúcar deve ser 0,2% maior que na safra passada. A safra 2017/18, apesar das margens positivas esperadas para a comercialização do açúcar, por conta da prática de hedge financeiro, traz um sinal de alerta com a queda acelerada dos preços no mercado livre internacional. Palavras-chave: cana-de-açúcar, preços, produção Abstract This publication presents the projections of agroindustrial production costs of the sugar-energy sector for the 2017/18 harvest in the Center-South region of Brazil. Characterized by the fall in harvested area and productivity, this harvest should show an increase in total sugar production costs and decrease in ethanol production costs. The cost of sugarcane should be 0.2% higher than in the previous crop. The 2017/18 harvest, despite the positive margins expected for the commercialization of sugar, due to the practice of financial hedging, brings a warning signal with the accelerated fall in prices in the international free market.

“…The energy required depends on the quality of raw material and the system used (Trubetskaya et al, 2019;Lowesmith et al, 2007). Thus, was considered the electric energy consumed in a period, which is expressed in (kWh) (Bigaton et al, 2015;Bigaton et al, 2016;Bigaton et al, 2017;Xin-Gang et al, 2015;Pedrazzi et al, 2016).…”

Biomass has a large share in the energy generation matrix, due to the regional economic benefits. This work has as main objective to evaluate the parameters used in the manufacture of briquettes produced with forest residues and the economic engineering for the manufacturer. The forest residues were: wood chips and chips of Eucalyptus spp. and barks of Pinus taeda. The evaluations were the chemical characterization of forest residues and the costs involved in the briquetting process. The forest residues presented extractive chemical composition and lignin. The production costs of the briquettes were affected mainly by the equipment, being the Pinus taeda barks the one that presented higher production cost. However, the production costs obtained in this study are approximately 20% lower than the production costs using traditional methods for forest firewood. The energy value from biomass allows the reduction of the dependence of energy, which can be used for the generation of steam or electricity, for subsistence. A fact for energy conversion is to evaluate the material moisture. It is suitable to burn residues with moisture between 45 to 55%. The consumed electric energy is important to evaluate the total costs. The energy required depends on the quality of raw material and the system employed. Forest residues is an important source for eco firewood production, contributing to energy generation and decreasing of the solid waste stored at the company. In this way, the new parameters for briquetting biomass forest wastes shown in this work, which is an important stage of the process, make economically viable and environmentally suitable the eco firewood production.
