Abstract Bioelectricity generation from sugarcane is significant across Brazil and related to regional market structure characteristics where the mills are located. To understand distribution conjuncture of this sector, study analyzes pattern location, concentration clustering bioelectricity supply bagasse in Brazil, for 2017 2022. The data were obtained Brazilian National Electric Energy Agency, methodology was based on indices scan statistics. results showed that Southeast region presented...
With increasing discussions about energy security and sustainable electricity generation, the supply of biomass resources, such as sugarcane energy, has become increasingly important for regional development. In this study, impact spatial dependence distribution sugar-energy bioelectricity in Brazil was examined using a econometric model. Data from ANEEL’s Generation Information System were utilized to represent Brazilian territory. Exploratory Spatial Analysis (ESDA) employed method, with...
In Northeast Brazil, the use of biomass for energy generation is settled on traditional productive arrangements, such as a sugarcane production system in humid Atlantic coastal area and firewood extraction from native tropical dry forests west. parallel, substantial amounts other sources, residues agricultural or urban processes, are still little used wholly wasted, fudging opportunity to generate new value chains based these sources. We hypothesize that using non-traditional sources produce...
This study analyzed the evolution and degree of global concentration pulp exports from 1961 to 2014. In order measure analyze concentration, following indicators were used: Concentration Ratio [CR(k)]; Herfindahl-Hirschman Index (HHI); Theil Entropy (E); Hall Tideman (HTI); Comprehensive (CCI); Gini Coefficient (G). We concluded that there was a tendency growth in during period due an increase demand driven by population per capita consumption, enhancing number exporting countries. The CR(k)...
This study analyzed the regional concentration of gross production value (GPV) firewood in Paraíba from 1994 to 2014. It measured by means Concentration Ratio [CR(k)] Herfindahl-Hirschman Index (HHI), Theil's Entropy (E), Hall-Tindelman (HTI), and Gini (G). From analyses performed, it was concluded that there growth GPV R$ 2.59 million 10.39 (in current terms). The CR(4) CR(8) municipalities indicated low concentration; microregions presented a moderately concentration, had high...
This study aimed to investigate how Industrial Symbiosis (IS) built around thermoelectric power plants (TPPs) located in forest-based clusters the southern plateau region of state Santa Catarina, Brazil, can stimulate adoption circular economy (CE) practices. Data were collected identify presence and purchase sale logs, processed wood, forest residues from companies within clusters, CE practices using ReSOLVE framework adopted two TPPs, which used black liquor as fuel. The results indicate...
Este trabalho analisou a concentração mundial das exportações de pellets entre 2012 e 2018. Utilizou-se os dados da Food and Agriculture Organization Of The United Nations – FAO foram empregados indicadores: Razão Concentração[CR(k)], Índice Hirschman-Herfindal (HHI), Entropia Theil (E), Coeficiente desigualdade Gini (G) o Hall-Tideman (HTI). Dos resultados notou-se que houve crescimento na quantidade madeira, com aumento 9,71 x106 t, em 2012, para 23,67 2018 . Observou-se domínio do...
Introducción: Los recursos forestales nativos, principalmente en el bioma caatinga brasileño, son importantes para la subsistencia de población rural como industria local cerámica roja y yeso.Objetivo: Analizar disparidad municipal valor bruto producción productos madereros nativos Paraíba, Brasil.Materiales métodos: Se utilizaron datos sobre (VBP) (leña, carbón madera rollo) los municipios Brasil, 1994 a 2017. Esta información está disponible Instituto Geografía Estadística Brasileñas...
Este artigo analisou a concentração regional da produção lenha nativa Paraíba, no período de 1994 2014. Os dados quantidade produzida foram extraídos extração vegetal e silvicultura disponíveis Instituto Brasileiro Geografia Estatística. A foi determinada por meio dos indicadores: Razão Concentração [CR(k)], Índice Herfindahl-Hirschman (HHI), Entropia Theil (E), Hall-Tindelman (HTI) o coeficiente Gini (G). partir das análises realizadas neste estudo, conclui-se que estudado houve uma redução...
Forest based power plants are alternatives in the diversification of domestic energy supply Brazil, given growing demand for electricity recent decades. Evidences space-time clusters contribute to understanding regional development associated with correlated activity. Therefore, this paper analyzed conglomerates Brazilian forest-based plants, from 2000 2019. The data used were Generation Information System National Electric Energy Agency (ANEEL)-SIGA. It detected existence by means scan...
This study analyzes the concentration and conglomerate spatial distribution of forest-based thermoelectric plants in Brazil, 2018. Herein, we spatially identified different Brazilian regions states, measured state concentrations (levels 1 2 forest) using various indicators, including ratio ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CR</i> <inline-formula xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$k$...
This paper analyzed the concentration and conglomerates of black liquor thermoelectric plants in Brazil, 2018. Data from generation information system National Electric Energy Agency (ANEEL) were used. Concentration was measured using Ratio CR(k), Herfindahl-Hirschman Index (HHI), Theil Entropy (E) Gini Coefficient (G) with scan statistics. The results showed southern region largest number installed power. state power for CR(k) moderately high to very high, inferring an oligopolistic market...
Este trabalho dimensionou o desenvolvimento brasileiro das florestas plantadas para fins energeticos. A analise foi realizada por meio de contextos historicos e bibliograficos. analises realizadas, permitiu concluir que: a tecnica selecao especies potenciais no inicio do seculo XX primeiro passo rapido crescimento; os incentivos fiscais proporcionaram retomada crescimento economico alavancou plantios florestais energeticos; precos carvao vegetal foram influenciados pelos planos economicos,...
This study was to present a methodology for analyzing the distribution and spatial-time dependence of supply forest bioelectricity in Brazil, from 2000 2019. The data granting biomass thermoelectric plants were obtained National Electric Energy Agency (in Portuguese Agência Nacional de Energia Elétrica –ANEEL). It used exploratory analysis spatial data, as neighborhood criteria weighting matrices k-neighbors closest based on distance, well global local Moran indices detect presence...
The increasing demand for natural resources human needs promotes growing conflicts due to the demands from different activities. For this reason, there has also been an interest in developing technologies based on Water–Energy–Food (WEF) nexus perspective. In semi-arid region of northeastern (NE) Brazil, implementing biodigesters small farmers is initiative that appears be aligned with global agendas and WEF concept. This research aimed evaluate integration a small-scale biodigester...
ABSTRACT Charcoal has an economic, social and environmental importance, because in addition to being a source of energy, it generates employment income the rural environment. Therefore, knowing your market is fundamental for decision-making those segments that depend on this raw material. This work analyzed regional concentration charcoal production state Paraíba, Brazil, from 1994 2016. The data used measure (in tons) native Paraíba were obtained Brazilian Institute Geography Statistics...
