“…In general, biofuels can be carbon neutral, carbon negative, or carbon sources, depending on how much CO 2 (and other greenhouse gases) is removed from or released into the atmosphere during crop growth and biofuel production (Tilman et al 2006). For biomass to be considered as a CO 2 neutral energy resource it is assumed that CO 2 produced is absorbed by growing plants in a relatively short cycle (López-Rodríguez et al 2009;Voivontas et al 2001;Moghtaderi et al 2006).…”

The aim of this paper was to analyze energy-related properties of forestry and agricultural wastes for energy production purposes, and to compare them with fossil fuels. The forestry wastes used were red cedar, Eucalyptus, and Pinus wood shavings. The agricultural wastes analyzed were rice husk, coffee wastes, sugar cane bagasse, maize harvesting wastes, and bamboo cellulose pulp. The forestry wastes presented more suitable properties for bioenergy production than the agricultural wastes. Desirable energetic properties were found for coffee wastes. The opposite was verified for rice husks. Among the biomass studied, coffee wastes presented the highest equivalent in fossil fuel volume and hence may lead to the highest decrease in CO 2 emissions by fossil fuels used in Brazil for steam and heat production. The results suggests that CO 2 benefits can be obtained if bioenergy is generated in the same locale where biomass is produced, avoiding CO 2 cost of logistics and leading to greater end-use efficiency. The present work promotes the widespread use of different lignocellulosic wastes for bioenergy production and gives useful information for the planning and the control of power plants using biomass.

“…A grande vantagem da utilização da biomassa vegetal como fonte de energia consiste nas emissões neutras de dióxido de carbono. O CO 2 produzido a partir da queima da biomassa (oxidação) é absorvido pelas plantas, por meio do processo fotossintético, que crescem em um ciclo relativamente curto (LÓPEZ-RODRÍGUEZ et al, 2009;MOGHTADERI et al, 2006;VOIVONTAS et al, 2001).…”

EVALUATION OF Coffea arabica L. WOOD QUALITY AS A SOURCE OF BIOENERGYABSTRACT: This work aimed to evaluate, through principal component analysis, the quality of Coffea arabica L. wood obtained from different growth systems and varieties as a source of bioenergy. Wood from three different growth systems (natural, conventional and organic) and two different varieties (Mundo Novo and Catuaí) were used, totalizing six treatments. The contents of elementary components (C, H, N, S and O), ash, lignin, total extractives and holocellulose, basic density, the higher heating value, the lower heating value, as well as the lower and higher volumetric heating values of the analyzed woods were quantified. Principal components multivariate statistical analyses were conducted. The scores of the principal components of interest were determined as a way to divide the woods into groups. Group I was composed by the wood from the organic coffee "Mundo Novo" and natural "Mundo Novo"; Group II by the organic "Catuaí", and Group III by the wood from convencional "Mundo Novo", natural "Catuaí" and convencional "Catuaí". Wood residues from the species Coffea arabica L. showed great potential for energetic use, especially the woods from the conventional systems and the "Catuaí" Variety. Woods from Group III stood out, due to the high volumetric heating values , basic density, lignin content and higher heating value. However, the woods of this group showed high nitrogen content.

“…Several studies have been conducted in the agro-energy planning scope using GIS in many information scales. VOIVONTAS et al (2001) evaluated the production potential of electricity from agricultural residues integrating spatial and economic data in the Crete Island, pointing out that this type of system is capable to generate results for decision making in the energy scope and presents high flexibility regarding application in several locations. Concerning sugarcane to agro-energy planning, there is a lack of studies using this sort of platform but they demonstrate a great potential for application, as FRANCO (2008) evaluated in the study of potential areas for bioenergy expansion in the state of São Paulo.…”

ABSTRACT:The present study aims to present the main concepts of the sugarcane straw to energy planning. Throughout the study, the subject is contextualized highlighting broader aspects of sustainability, which is considered the main driver towards agro-energy modernization. Concerning sugarcane straw, we first evaluated its availability regarding technical and economic aspects, and then it summarized the straw production chain for energy supply purposes. As a proposal to support agro-energy planning, it is presented some spatial tools that have been barely used in the Brazilian energy planning context so far. Therefore, working on straw to electricity associated with supply chain basis, we developed a conceptual model to spatially assess this bioenergy system. Using the model proposed, it is described the whole supply chain at state level, which accounted the potential of a single mill to explore straw, as well as main costs associated with straw acquisition, investments on the straw recovery routes and electricity transmission. Bearing these concepts in mind, it is fully believed that spatial analysis can bring important information for agro-energy action plans.KEYWORDS: sugarcane, straw, agro-energy planning, geographic information system. IDENTIFICAÇÃO, AVALIAÇÃO E ORDENAMENTO DE CONCEITOS PARA O PLANEJAMENTO AGROENERGÉTICO E AS POSSIBILIDADES DA ANÁLISE ESPACIALRESUMO: O presente artigo busca apresentar os principais conceitos envolvendo um planejamento energético específico da palha da cana-de-açúcar. Ao longo do trabalho, procurou-se contextualizar o tema por meio de questões de sustentabilidade, considerada um dos principais indutores em direção à modernização da agroenergia. Considerando a palha da cana de açúcar, avaliou-se primeiramente sua disponibilidade envolvendo aspetos técnicos e econômicos, e posteriormente caracterizou-se a cadeia de produção da palha para energia. Como proposta para auxílio ao planejamento agroenergetico, apresentou-se algumas ferramentas espaciais que até então pouco têm sido utilizadas para planejamento energético no Brasil. Deste modo, trabalhando o potencial de palha para eletricidade associado à sua cadeia de produção, desenvolveu-se um modelo conceitual para se avaliar espacialmente esse sistema bioenergético. Utilizando o modelo proposto, foi possível descrever toda a cadeia de produção da palha para energia em um nível estadual, envolvendo o potencial que cada usina pode explorar, bem como os principais custos associados à sua aquisição, investimentos relacionados à rota de recuperação e em linhas de transmissão. Por meio dos conceitos abordados, acredita-se que análise espacial pode trazer importantes informações para planos de ação no âmbito agroenergético.
