ABSTRACT &#x2013; Faced with the transition in the global energy structure with the shift in consumption of fossil fuels to renewable and clean sources, there has been an increase in the demand for forest biomass for energy purposes, especially wood pellets, and imports have grown in recent years. Therefore, this study analyzed the world concentration of pellet imports from 2012 to 2018. Data on pellet imports were obtained from the Food and Agriculture Organization of the United Nations (FAO), and the following indicators were used to measure the concentration: Concentration Ratio [CR(k)], Hirschman-Herfi ndal Index (HHI), Theil Entropy Index (E), Gini Inequality Coeffi cient (G) and the Hall-Tideman Index (HTI). The results showed a growth of 16.67% p.a. of global pellet imports, from 8.76 million tons (t) in 2012 to 22.15 million tons in 2018. The CR(k) indicated very high concentration for countries and high in the subcontinents. The HHI showed a high concentration for continents and subcontinents and a moderate concentration for countries. Entropy and HTI corroborated the analyzes found in the HHI. The G pointed out strong inequality for all territorial levels and showed trends towards a reduction in inequality as of 2015. The reduction in the concentration in the fi nal years of study is related to the expansion and technological diff usion of energy conversion of the densifi ed biomass, which makes this fuel more aff ordable.

RESUMO &#x2013; Diante da transi&#xE7;&#xE3;o na estrutura energ&#xE9;tica mundial, com o deslocamento do consumo dos combust&#xED;veis f&#xF3;sseis para fonte renov&#xE1;veis e limpas, registra-se um aumento da demanda por biomassa florestal para fins energ&#xE9;ticos, em especial os pellets de madeira, e as importa&#xE7;&#xF5;es t&#xEA;m crescido nos &#xFA;ltimos anos. Logo, este artigo analisou a concentra&#xE7;&#xE3;o mundial das importa&#xE7;&#xF5;es de pellets, de 2012 a 2018. Os dados de importa&#xE7;&#xF5;es de pellets foram obtidos da Food and Agriculture Organization of the United Nations &#x2013; FAO e para mensurar a concentra&#xE7;&#xE3;o foram utilizados os indicadores: Raz&#xE3;o de Concentra&#xE7;&#xE3;o [CR(k)], &#xCD;ndice de Hirschman-Herfi ndal (HHI) &#xCD;ndice de Entropia de Theil (E), Coefi ciente de desigualdade de Gini (G) e o &#xCD;ndice de Hall-Tideman (HTI). Os resultados apontaram um crescimento de 16,67% a.a. da importa&#xE7;&#xE3;o mundial de pellets, saindo de 8,76 milh&#xF5;es toneladas (t), em 2012, para 22,15 milh&#xF5;es de t em 2018. Quanto aos &#xED;ndices de concentra&#xE7;&#xE3;o, o CR(k) indicou concentra&#xE7;&#xE3;o muito alta para os pa&#xED;ses e alta nos subcontinentes. O HHI apresentou concentra&#xE7;&#xE3;o alta para os continentes e subcontinentes e uma concentra&#xE7;&#xE3;o moderada para os pa&#xED;ses. A Entropia e o HTI corroboraram as an&#xE1;lises encontradas no HHI. O G apontou forte desigualdade para todos os n&#xED;veis territoriais e apresentou tend&#xEA;ncias de redu&#xE7;&#xE3;o na desigualdade a partir de 2015. A redu&#xE7;&#xE3;o da concentra&#xE7;&#xE3;o, nos &#xFA;ltimos anos de estudo, encontra rela&#xE7;&#xE3;o com a expans&#xE3;o e a difus&#xE3;o tecnol&#xF3;gica de convers&#xE3;o energ&#xE9;tica da biomassa densificada, o que torna o combust&#xED;vel mais acess&#xED;vel.
