1. 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

2. 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

5. Effect of Calcination Temperature on the Pozzolanic Activity of Brazilian Sugar Cane Bagasse Ash (SCBA)
This study evaluated the feasibility of using sugar cane bagasse ash (SCBA), a by-product of the sugar cane ethanol industry, obtained under controlled calcination as a partial replacement for Portland cement in mortars. Materials with pozzolanic characteristics may be used to partially replace cement in mortars or concrete and are known to provide durabilit

6. Otimização do pré-tratamento hidrotérmico da palha de cana-de-açúcar visando à produção de etanol celulósico
The sugarcane industry has huge potential for biorefinery concept application, given its development in recent years. In this context, cane sugar straw has become an attractive raw material for biofuel production. This study aims to investigate the chemical composition of cane sugar straw from different regions of Brazil, and to optimize a hydrothermal pretr

7. Evaluation of stress tolerance and fermentative behavior of indigenous Saccharomyces cerevisiae
Sixty six indigenous Saccharomyces cerevisiae strains were evaluated in stressful conditions (temperature, osmolarity, sulphite and ethanol tolerance) and also ability to flocculate. Eighteen strains showed tolerant characteristics to these stressful conditions, growing at 42 ºC, in 0.04% sulphite, 1 mol L-1 NaCl and 12% ethanol. No flocculent characteristi

8. Mudanças nos uso e preços de terras do Estado de São Paulo - período de 1995 a 2010 / Changes in land use and farmland prices in São Paulo State: from 1995 to 2010
This work has examined major changes in land occupation in different regions of São Paulo State to determine major vectors of the observed changes in farmland prices, between 1995 and 2010. This period encompasses both the period of retraction and deregulation of the sugarcane sector, after the extinction of Proálcool program, and the new stage of investme

9. Aquisições, fusões e alianças estratégicas na configuração da cadeia sucroenergética brasileira / Acquisitions, mergers and strategic alliances in the configuration of the Brazilian sugar, ethanol and bioenergy chain
A cadeia do açúcar tem sido um dos ícones da economia brasileira por séculos. Em meados da década de 1970, ela passou pela primeira mudança expressiva, a introdução do Proálcool, programa de combustível alternativo apoiado pelo governo. Após a recente virada do século, a cadeia sucroalcooleira passou por nova mudança, dessa vez fomentada pela te
