“…The growth observed in our study is comparable with data reported for E. urophylla in different parts of the world; the diameters and heights were similar to those reported by Oliveira et al [40] in clonal lines of E. urophylla in Brazil. These authors reported diameters from 9.5 cm to 20.8 cm and heights from 16.9 m to 29.4 m at 6 years of age.…”

“…The clonal lines studied achieved the MAIs [11.1 m³ ha⁻¹ year⁻¹ for F24 and 83.1 m³ ha⁻¹ year⁻¹ for F18], and they were similar to those reported by Oliveira et al [40] (11.03-94.99 m³ ha⁻¹ year⁻¹) in E. urophylla in Brazil. Sein and Mitlöhner [1] reported lower increments (60 m³ ha⁻¹ year⁻¹) in Vietnam, as did Xu et al [46] (29.8 m³ ha⁻¹ year⁻¹) in China and Manasa et al [47] (27.24-31.56 m³ ha⁻¹ year⁻¹) at six years of growth in India.…”

Eucalyptus urophylla is important for the establishment of commercial forest plantations in Mexico. Genetic improvement programs are currently being implemented to increase timber productivity. The objectives of this study were to evaluate the adaptability and growth stability of 26 clonal lines of E. urophylla in Acrisol and Fluvisol soils and to identify the most suitable genotypes for each soil type. Tree survival, diameter at breast height, and total height were measured annually for six years. These variables were used to estimate individual volume, volume per hectare, and mean annual (MAIv) and current annual (CAIv) volume increment. Survival ranged from 14 to 100% in the Acrisol soil and from 0 to 89% in the Fluvisol soil. Volume per hectare ranged from 65.3 to 488.7 m3, MAIv from 11.1 to 83.1 m3 ha−1 year−1, and CAIv from 2.4 to 134.7 m3 ha−1 year−1. Individual heritability (Hi2) was moderate (0.29–0.49) while the mean heritability of the cloned lines was high (0.73–0.90), indicating that growth is subject to high genetic control. Diameter, height, and volume presented no genotype × environment interaction effects, demonstrating stability in the growth of the clonal lines in both soil types.

“…A densidade básica da madeira é um importante fator que pode afetar a geração de energia a partir da queima de madeira (Oliveira et al, 2021). Em geral, madeiras com densidades mais altas tendem a ter um maior teor de energia por volume e a queimar mais lentamente do que madeiras com densidades mais baixas (Lima et al, 2022).…”

Objetivo: o objetivo desta pesquisa foi determinar as características físicas, químicas e energéticas da madeira e do carvão vegetal da espécie Prosopis juliflora, utilizada em indústrias de cerâmicas vermelhas da região semiárida. Métodos: Foi utilizada a madeira de algaroba (Prosopis juliflora), espécie exótica, presente na região semiárida e com elevado uso para fins energéticos nas cerâmicas da região. O material coletado foi obtido em uma cerâmica localizada no município de Santa Luzia, Paraíba, Brasil. Foi determinada a densidade básica, composição química (extrativos, lignina e holocelulose), química imediata (materiais voláteis, carbono fixo e cinzas) e poder calorífico da madeira. E após o processo de pirólise da madeira, foi determinada o rendimento gravimétrico, densidade aparente, química imediata e poder calorífico do carvão vegetal. Resultados: Tanto a madeira quanto o carvão vegetal da espécie de P. juliflora apresentam características favoráveis para fins energéticos. Com alta densidade energética e poder calorífico, maior percentual de materiais voláteis e ligninas, e baixo de cinzas na madeira, e maior rendimento gravimétrico em carvão vegetal. Conclusão: Assim, P. juliflora possuí potencial para industria de cerâmica vermelha, contudo, recomenda-se a utilização da espécie em forma de madeira (lenha), por ser um método economicamente mais viável.

“…The addition of sewage sludge increased the energy density of the briquettes, with the treatment using 100% sewage sludge showing an energy density exceeding 20 MJ/m 3 , while the use of 100% pine sawdust generated an energy density close to 10 MJ/m 3 (Figure 4). Energy density is given by the product of the material density and its higher heating value [38]. Although the higher heating value of wood is 20.3 MJ/m 3 and that of sewage sludge is 14.6 MJ/m 3 , sewage sludge has a higher density, allowing for a greater mass in briquette formation and, consequently, a higher energy density of the material.…”

The lack of adequate sanitation in Brazil overloads the health system and causes deaths. The utilization of sewage sludge hinders advancements in water treatment. This study aimed to assess the feasibility of producing briquettes by blending sewage sludge with Pinus sp. sawdust. The sewage sludge was sourced from a water treatment facility, while the Pinus sp. sawdust was obtained from a sawmill. Elemental analysis, proximate analysis, and calorific value were evaluated for both biomasses. Briquettes were manufactured using a hydraulic press, varying the proportion of sewage sludge from 0% to 95%, followed by thermogravimetric analysis. Pinus sp. sawdust exhibited higher carbon, oxygen, and hydrogen content, whereas sewage sludge contained more nitrogen and sulfur. The sawdust had greater fixed carbon content, volatile matter, and calorific value, while the sewage sludge had higher ash content. Samples with higher sewage sludge content showed better thermal resistance, with 100% sewage sludge retaining 63.3% mass after exposure to 950 °C. Briquettes with higher sewage sludge content had increased energy density. Considering the elevated nitrogen, sulfur, and ash content, sewage sludge should be limited to 5% in briquette production with Pinus sp. sawdust. This research underscores a significant avenue for sewage sludge utilization and sustainable bioenergy production.
