“…Mathematical modeling and optimization were also applied to planning and scheduling of bioethanol processes. Grisi et al [20] presented a MILP formulation for the short-term scheduling of the integrated processes for sugar, bioethanol, biogas and bioelectricity production. In Corsano et al [21] a MINLP model for the simultaneous optimization of the design, operation, scheduling, and planning of a fermentation network is proposed.…”

“…The model, formulated as a MILP, addresses sustainability issues such as the use of food crops, land requirements of second generation crops and competition for biomass with other sectors. Grisi et al [20] present a MILP formulation to solve the short term operation of biorefineries from sugarcane industry. Cucchiella and D'Adamo [21] analyze the specific characteristics of SC of renewable energies, considering the relationships among environmental, economic and social aspects.…”

“…Consequently, several studies have aimed to analyze the techno-economic viability of future options, such as the combined cycles of biomass gasification (JIN et al, 2009) and the insertion of straw as a fuel in technological routes on a commercial scale (GRISI et al, 2011). Furthermore, external analysis on political and environmental factors seeks to boost the biomass to electricity as an important alternative to diversify energy matrix in many countries (JÄGER-WALDAU et al, 2011).…”

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.
