“…Juvenile wood is a plant tissue formed by the immature cambial meristem, and compared to mature wood, juvenile wood has smaller cells, shorter fibres, thinner cell walls, and higher cellulose microfibrillar angle with lower density, strength, and stiffness (Balboni et al, 2020). The transition from juvenile to mature wood could take around 6 to 15 years or up to 20 years depending on the species, meaning that trees grown in short-rotation plantations contain a high percentage of juvenile wood.…”

Australia has significant wood resources in its native forest, but the resource available for harvest becomes lesser due to the conversion of native forest to conservation reserves. The natural occurrences of bushfires, droughts, and cyclones are highly destructive, making the situation worse. The shortage of wood resources is having a significant negative impact on Australia because wood is so scarce that they cannot meet domestic demands, especially durable wood. Australia cleared approximately 100 million hectares of its land to establish forest plantations, and two million trees were planted. However, most of these plantations are for pulpwood production; however, their application for high-value products is limited due to their undesirable properties. Wood modification is a process of improving unfavorable wood properties to be utilized for a wide range of applications. Australia has not adopted any of these modification processes; it still depends on the less toxic wood preservative to treat wood. This study focuses on the recent advancement in industrial wood modification worldwide and how it may be used to modify Eucalyptus wood for high-value applications. The opportunities and suggestions for Eucalyptus wood modification in Australia will be discussed. Before the study concludes, the future of commercial wood modification for Eucalyptus plantation in Australia will also be presented.

“…Juvenile wood, in turn, is a minor problem in hardwoods compared to softwoods, the usual raw material for engineered wood products (Zobel & Sprague, 1998). Balboni et al (2020) confirmed juvenile wood has lower strength than mature wood, but they share the same strength-to-density relationship. Products manufactured with juvenile wood from Eucalyptus plantations had returned adequate properties (Liao et al, 2017;Pagel et al, 2020), with a special reference to the roof trusses made with young E. grandis wood, which is already well established in the South African market (Wessels et al, 2020).…”
