1. THE SUCCESS OF THE BRAZILIAN ALCOHOL PROGRAM (PROÁLCOOL) - A DECADE-BY-DECADE BRIEF HISTORY OF ETHANOL IN BRAZIL
ABSTRACT The National Alcohol Program (Proálcool) was a strategic policy of the Brazilian government to replace petroleum-based fuels with alcohol (ethanol). Based on the review, we can choose the 1960s as a start point for a leap in development. Over the 500 years of sugarcane history in Brazil, the crop enters the second decade of the 21st century with ex

2. Characterization of the solid residue generated in the detoxification step of sugarcane bagasse hemicellulosic hydrolysate and behavior in agricultural soils
ABSTRACT Overliming is an effective way of neutralizing and reducing the toxicity of the hydrolysates generated from acidic pretreatment of lignocellulosic biomass for ethanol production and others biotechnological products. Overliming generates a solid residue whose inadequate disposal may represent an environmental problem. This work aimed at the chemical

3. New Proposal for Sugarcane Vinasse Treatment by Hydrothermal Carbonization: An Evaluation of Solid and Liquid Products
Vinasse is a residue of ethanol production from sugarcane. In view of the problems associated with its disposal, this study aimed to propose a treatment for vinasse by hydrothermal carbonization. The influence of temperature (100 to 200 ºC), acidity (1.7 to 8.3%) and reaction time (12 to 48 h) on the hydrothermal treatment was evaluated, as well the charact

4. Interspecific Competition Between Sweet Sorghum and Weeds
RESUMO: Enquanto evidências indicam o sorgo sacarino [Sorghum bicolor (L.) Moench] como uma matéria-prima de etanol alternativa durante a entressafra da cana-de-açúcar (Saccharum officinarum L.), pouco se sabe sobre sua capacidade produtiva em condições adversas (sob competição com plantas daninhas, por exemplo). Portanto, o objetivo do presente estu

5. Analysis of the agricultural productivity of the sugarcane crop in regions of new agricultural expansions of sugarcane
Resumo O lançamento dos veículos bicombustíveis, no ano de 2003, propiciou a retomada da importância da produção de etanol e, consequentemente, numa nova fase de expansão do cultivo de cana-de-açúcar no Brasil. Embora o aumento da área de produção e da quantidade produzida de cana-de-açúcar mereça destaque no agronegócio brasileiro, o mesmo

6. ISOLATION AND IDENTIFICATION OF YEAST STRAINS FROM SUGARCANE MOLASSES, DATES AND FIGS FOR ETHANOL PRODUCTION UNDER CONDITIONS SIMULATING ALGAL HYDROLYSATE
ABSTRACT Yeast strains were isolated from sugar cane molasses (S1), dates (S2) and figs (S3) and the ethanol production was evaluated in batch condition. A comparison was made with the yeast Saccharomyces cerevisiae. The strains showed tolerant characteristics to stressful conditions like salinity and ethanol. The isolated strains produced ethanol; at 20 h o

7. Sprouting of pre-sprouted sugarcane seedlings and micrometeorological variables under photo-selective nets
RESUMO A cana-de-açúcar é uma gramínea que se destaca mundialmente na produção de etanol. O Brasil é o maior produtor mundial e líder na exportação, responsável por mais de 50% dos produtos derivados que são comercializados no mundo. Objetivou-se averiguar a influência de malhas fotosseletivas nas variáveis micrometeorológicas e na brotação

8. An Alternative and Simple Method for the Preparation of Bare Silica Nanoparticles Using Sugarcane Waste Ash, an Abundant and Despised Residue in the Brazilian Industry
Sugarcane waste ash, a Si-rich waste product, is generated in large quantities and creates a serious disposal problem in the Brazilian ethanol-sugar industry, affecting the environment and public health. Here, a simple method capable of generating bare silica nanoparticles utilizing this residue is demonstrated. Firstly, the crystalline silica present in sug

9. A methodology to determine size and shape of plots for sugarcane plantation
ABSTRACT: Brazil is the largest sugarcane producer in the world and the leader in the production of sugar and ethanol. Although sugarcane has become an important factor in the Brazilian economy, cultivation has presented many issues, for example, the problems due to burning before the manual harvest. The Brazilian authorities have approved a law that prohibi

10. Sugarcane Root Development and Yield under Different Soil Tillage Practices
ABSTRACT New strategies for sugarcane production have been very important since the incorporation of ethanol in the Brazilian energy mix in the early 1970s. Prior to planting sugarcane, the soil is prepared, and this process can affect root development and, consequently, sugarcane production. This study was conducted in an area of sugarcane crop renewal in t

11. Genome sequence of the H2-producing Clostridium beijerinckii strain Br21 isolated from a sugarcane vinasse treatment plant
Abstract We report on the nearly complete genome sequence of Clostridium beijerinckii strain Br21, formerly isolated from a sugarcarne vinasse wastewater treatment plant. The resulting genome is ca. 5.9 Mbp in length and resembles the size of previously published C. beijerinckii genomes. We annotated the genome sequence and predicted a total of 5323 genes. S

12. Proposal of stages by controlling the efficiency analysis in sugar and ethanol mills
Abstract This study aimed to identify the main points of control in the efficiency of the productive process in sugarcane mills. Thus, a two-stage DEA approach applied for a sample of 121 mills, distributed among the seasons of 2010/2011 until 2014/2015. The first stage separated the efficient mills in transforming the total recovered sugar (TRS) of the pro
