Sustainability Assessment of a Biorefinery Complex in Thailand
Shabbir H. Gheewala,Sébastien Bonnet,Kritana Prueksakorn,Pariyapat Nilsalab
Sustainability , 2011, DOI: 10.3390/su3030518
Abstract: In this paper, a biorefinery complex in Thailand was assessed vis-à-vis sustainability. The complex studied includes plantations of sugarcane and a biorefinery system composed of several units including, a sugar mill, power plant, ethanol factory and fertilizer plant. The assessment aimed at evaluating the environmental and socio-economic implications relating to molasses-based ethanol production and use, and maximized utilization of the biomass materials produced as part of the biorefinery complex. Global warming potential, human development index and total value added are the three indicators that were selected to perform the assessment. The results obtained revealed that the maximization of biomass utilization at the level of the biorefinery complex provide greenhouse gases emissions reduction benefits, enhanced living conditions for sugarcane farmers and employees of the biorefinery, and economic benefits, particularly with regard to profit and income generation. These results could serve as a first step to further improve and design indicators for sustainability assessment of biomass utilization.

Neotropical Entomology , 2008, DOI: 10.1590/S1519-566X2008000100017
Abstract: euetheola humilis (burmeister) is a scarabaeid pest of rice, sugarcane and corn cultures, that attacks the crops during both larval and adult phase. the occurrence of e. humilis was observed in a forest area with eucalyptus saligna smith, from votorantim celulose & papel (fazenda aroeira), in the municipality of candiota, rio grande do sul state. plants approximately 1m high were damaged by e. humilis adult insects near the stem base, what unraveled its cortex and led some of them to death. the attack was verified in about 10% of the eucalypts plants, in an area of approximately 30 ha.

Abstract: the objective of this work was to evaluate the adaptability and stability of early maturation sugarcane genotypes, as to yield of stalk and brix, in rio grande do sul state, brazil. fifteen early?maturing genotypes were evaluated in the 2009/2010 and 2010/2011 seasons, through the additive main effects and multiplicative interaction (ammi) analysis. genotype x environment interactions were highly significant and evidenced changes in the genotype ranking according to the environment. new genotypes exceeded the standard early genotype rb855156 for productivity and stability, although it still stands out for its high productivity, moderate stability and wide adaptability. genotype rb966928 stood out for its richness and yield of brix, moderate stability and wide adaptability. salto do jacuí, rs, brazil, is the most suitable site for preliminary tests of genotype selection.

Biotemas , 2009,
Abstract: The Swallow-tailed Hummingbird (Eupetomena macroura) is recorded for all Brazilian regions. However, there is no documented record for the state of Rio Grande do Sul, southern Brazil. This note reports a photographic record of the species for the municipality of Cap o da Canoa, northern coast of Rio Grande do Sul.

Agricultural Sciences (AS) , 2017, DOI: 10.4236/as.2017.89064
Abstract: The sugar and bioethanol industry generate large amounts of filter cake and vinasse, residues that are applied to sugarcane fields as conditioners and organic fertilizers. However, these may be significant sources of greenhouse gases emissions to the atmosphere. This study assessed the impact of sugarcane straw biochar on the emissions of CO2, CH4and N2O promoted by filter cake and vinasse applied to soil, and its effects on the chemical properties and bacterial communities of a Typic Hapludox and a Quartzipsamment. A laboratory incubation was conducted for 100 days with both soils under five treatments: vinasse and filter cake amendment (FV), plus biochar at 10 (FV + B10), 20 (FV + B20) and 50 (FV + B50) Mg·ha-1, and a control. Soil pH, available P and exchangeable base contents increased with biochar added to sandy soil. Mineral N decreased with biochar addition to both soils. The FV treatment increased CO2 emissions by 5-fold and 2.4-fold in sandy and clayey soils, respectively, compared to the control. Moreover, FV +B10 increased CO2 emissions by 4% and 6.4% in sandy and clayey soils, respectively, compared to FV. Cumulative N2O emissions in FV were 537% and 125% higher in sandy and clayey soils, respectively, compared to the control. Nevertheless, increasing biochar amendment rates reduced N2O emissions from 24% to 34% in sandy soil, and from 14% to 56% in clayey soil. CH4 emissions were negligible. The effects of filter, vinasse and biochar amendments on soil amelioration were closely related to its buffering capacity. Temporal changes on bacterial community structure were more pronounced in the sandy soil compared to clayey, and indicated that N2O emission mitigation in clayey soil was directly related to biotic mechanisms, while abiotic mechanisms caused by biochar played a more important role in mitigating N2O emissions in sandy soil.
Gerenciamento dos resíduos da disciplina química inorganica II do curso de química da Universidade Federal do Rio Grande do Sul
Gerbase, Annelise Engel;Gregório, José Ribeiro;Calvete, Tatiana;
Química Nova , 2006, DOI: 10.1590/S0100-40422006000200036
Abstract: beginning students in chemistry usually do not realize that wastes generated in their experimental classes constitute an environmental problem and that residues must be treated or disposed of in a suitable way. in this manuscript we describe the work that we have been doing in the inorganic chemistry course of the federal university of rio grande do sul with the objective of creating a critical consciousness in the students about the chemical wastes they generate. with this policy, students are required to take into account the nature of the residues they generate, how they can treat or segregate them, and how they can keep them in a suitable way for final destination, instead of simply throwing them away.
