“…This is due to the direct relationship between volumetric production and greater density of plants per area, which reflects on a greater amount of dry matter. These results are supported by , Caron et al (2015), and Saraiva et. (2017), who studied different species of Eucalyptus and planting spacings.…”

Background:The objective of this study was to evaluate the quality indicators for wood and charcoal from the Eucalyptus urophylla x Eucalyptus grandis hybrid (Clone GG 100) in different planting spacings. The study was conducted with the hybrid using the spacings of 2×1, 2×2, 3×2, and 3×3 m. The chemical properties of wood and charcoal were analyzed, and dry wood mass and energy per hectare were estimated. The data were subjected to the t test for comparison of means. Moreover, principal component analysis was conducted to assess the relationships between wood and charcoal indicators as a function of spacing. Results:The 2×2 m spacing showed the highest values for dry wood mass, lignin mass, mass of charcoal, and energy. The wider spacings of 3×2 and 3×3 m resulted in wood and charcoal of increased quality by showing wood of greater resistance to thermal degradation and charcoal of higher yield. Conclusion:Spacing between trees influenced wood quality indicators. The 2×2 m spacing showed higher estimates of mass and energy per hectare. However, wide spacings with an area greater than 6 m 2 are more suitable for charcoal production due to their superior wood properties, especially basic density and total lignin, which influence gravimetric yields and bulk density.

“…The practices of feedstock (i.e., sugarcane, eucalyptus, and macauba) cultivation and their related emissions are highly dependent on the locations and technologies available. Thus, data on emissions for feedstocks production were obtained from the most recent context-specific LCA/LCI studies of sugarcane production in Sao Paulo [44], average eucalyptus production (forest production subsystem) in Brazil [45,46], and macauba cultivation in Minas Gerais [47].…”

Human Health Impacts of Aviation Biofuel Production: Exploring the Application of Different Life Cycle Impact Assessment (LCIA) Methods for Biofuel Supply Chains

2020

The life cycle human health (HH) impacts related to aviation biofuels have been understood in a limited way. Life cycle impact assessment (LCIA) methods for assessing HH are often associated with a high level of uncertainty and a low level of consensus. As a result, it remains challenging to perform a robust assessment of HH impacts with a suitable LCIA method. This study aims to systematically compare six commonly used LCIA methods for quantifying HH impacts, in order to empirically understand the potential impacts of aviation biofuel production on HH and how the results are affected by the choice of methods. Three aviation biofuel production pathways based on different feedstocks (sugarcane, eucalyptus, and macauba) were analyzed and compared to fossil aviation biofuels, on the basis of a functional unit of 1 MJ aviation fuel. The majority of the LCIA methods suggest that, in respect to midpoint impacts, macauba-based biofuel is associated with the lowest impacts and eucalyptus-based biofuel the highest; whereas at endpoint level, the results are more scattered. The LCIA methods agree that biomass conversion into aviation biofuel, H2 production, and feedstock cultivation are major contributors to life cycle HH impacts. Additionally, we provide a guideline for determining an appropriate method for assessing HH impacts.

“…Os plantios florestais com fins energéticos começaram a surgir no Brasil a partir da década de 1970, quando apareceu o conceito de florestas energéticas, a partir da necessidade de se produzir biomassa florestal em maior escala para atender a indústria de carvão vegetal (Brito, 2013). Em Minas Gerais, diversos projetos e experimentos de florestas energéticas foram desenvolvidos, através de monocultivos adensados de espécies do gênero Eucalyptus em rotações curtas, isto é, ciclos de cortes de 2 a 3 anos, e espaçamentos de 1,0 x 1,5 m; 2,0 x 1,0 m (Couto & Muller, 2013;Bernstad Saraiva et al, 2017).…”

O objetivo dessa revisão foi avaliar o potencial da produção de biomassa florestal com fins energéticos em Sistemas Agroflorestais (SAFs). O uso da madeira e de resíduos florestais para energia tem sido bastante estimulado no Brasil e no mundo nas últimas décadas, em razão de questões ambientais e da sua viabilidade técnica e econômica. No entanto, seu desenvolvimento em SAFs ainda necessita de mais estudos. Foram analisadas as principais características técnicas e econômicas para a produção de madeira para energia em SAFs, destacando espécies arbóreas, qualidade de sítio, características socioeconômicas e práticas agrossilviculturais. Os principais estudos encontrados são oriundos da Europa, Estados Unidos, Ásia e África, enquanto que no Brasil ainda existe escassez de trabalhos nesse tema, embora o país seja grande consumidor de biomassa florestal para energia. Todos os trabalhos encontrados indicaram que existe potencial técnico e econômico para a geração de energia de biomassa em SAFs, tanto para o abastecimento do produtor rural, quanto para a comercialização da madeira com qualidade para uso energético. Contudo, essa relação depende fundamentalmente de: maior estruturação do mercado para biomassa florestal, características socioeconômicas regionais e condições ambientais.
