“…These cation exportations in leaves and bark can reduce soil fertility and would reduce the yields, as occurred in the annual crops in Uruguay in the last decade [20]. In the same trend, Bentancor et al [65] and Resquin et al [66] showed the need to find a tradeoff between nutrient removal and wood production for forest plantation developments for bioenergy in northeastern soils, where the plantation density is a second variable that must be considered [66][67][68][69].…”

The current global climate change, the 2030 Agenda, and the planetary boundaries have driven new development strategies, such as the circular economy, bioeconomy, and biorefineries. In this framework, this study analyzes the potential availability and sustainability of the wood supply chain for a small-scale biorefinery aiming at producing 280–300 L of bioethanol per ton of dry biomass, consuming 30,000 t of dry biomass per year harvested in a 50 km radius. This wood production goal was assessed from Eucalyptus grandis stands planted for solid wood in northeastern Uruguay. Moreover, to understand the environmental performance of this biomass supply chain, the energy return on investment (EROI), carbon footprint (CF), and potential soil erosion were also assessed. The results showed that the potential wood production would supply an average of 81,800 t of dry mass per year, maintaining the soil erosion below the upper threshold recommended, an EROI of 2.3, and annual CF of 1.22 kg CO2−eq m−3 (2.6 g CO2−eq MJ−1). Combined with the environmental performance of the bioethanol biorefinery facility, these results would show acceptable values of sustainability according to EU Directive 2009/28/ec because the bioethanol CF becomes 1.7% of this petrol’s CF.

“…2001). Eucalyptus had high variability and its anatomical, chemical, physical and mechanical properties were affected by climate, soil, variety, genetics, age, tree height and provenance (Resquin et al 2019;Teixeira et al 2021). Of these, anatomical, chemical, physical and mechanical properties encompass many more aspects.…”

In order to make full use of Eucalyptus resources in Yunnan and to realize the oriented cultivation of Eucalyptus plantations and high-value utilization of Eucalyptus for wood composites, this paper analyzed the change pattern of basic wood properties and characteristics including the wood anatomical features, chemical components, physical and mechanical properties, as well as X-ray diffraction of 6–9 years old E. urophylla×grandis 3229 and E. globulus. The results showed that the cellulose content, crystallinity and hot water extractives of Eucalyptus decreased with wood age, while the lignin and hemicellulose content showed the opposite trend; pH value was positively correlated with wood height and negatively correlated with wood age. The basic density of E. urophylla×grandis and E. globules was 0.46 ~ 0.54 g/cm3, belonging to medium-low density wood. The dimensional stability and bengding strength of E. globulus were higher than those of E. urophylla×grandis; the compressive strength of E. urophylla×grandis was grade 5 (95.45 ~ 113.54 MPa) and its hardness was grade 2–3(The end hardness of 9 year reaches 5357.97 MPa.). The study showed that E. urophylla×grandis over 7 to 8 years and E. globulus over 6 year had diameters and mechanical properties that meeting the requirement of Chinese industrial timber standards.
