University of Â鶹´«Ã½<\/span> at M\u0101noa researchers are working to determine whether Â鶹´«Ã½<\/span>-grown eucalyptus could become a reliable source of lumber for construction, helping reduce the state\u2019s reliance on imported building materials while supporting healthier forests.<\/p>\n

The project, led by Jun Wang, an assistant professor in the Department of Civil, Environmental and Construction Engineering<\/a>, received a $300,000 USDA<\/abbr> Forest Service Wood Innovation Grant to establish the engineering standards needed for eucalyptus to be used in structural applications.<\/p>\n

Although Â鶹´«Ã½<\/span> has more than 34,000 acres of managed eucalyptus plantations, the wood is rarely used in construction because engineers and builders lack the design data needed to certify it for structural use. If successful, the research could create new opportunities for Â鶹´«Ã½<\/span>\u2019s forestry and wood products industries while reducing shipping costs, supply chain risks and carbon emissions associated with importing lumber. Researchers also say putting more eucalyptus to use could encourage better forest management by reducing excess wood that can contribute to wildfire fuel.<\/p>\n

The research team will work with state agencies, forest landowners and industry partners to harvest trees, produce lumber and test its strength and durability. The findings will help establish engineering design values needed for commercial construction and could lay the groundwork for future engineered wood products made in Â鶹´«Ã½<\/span>.<\/p>\n

“Our goal is to determine whether a resource that\u2019s already growing in Â鶹´«Ã½<\/span> can safely be used to build the homes, schools and infrastructure our communities need,” Wang said. “If we can provide the engineering data the construction industry needs, we can help create a more resilient local building supply while giving our students the opportunity to solve real challenges facing Â鶹´«Ã½<\/span>.”<\/p>\n

The research also will benefit students. Wang\u2019s team received an $8,000 American Society for Engineering Education grant to incorporate Â鶹´«Ã½<\/span>-grown eucalyptus into civil engineering courses. The new curriculum will give students hands-on experience evaluating sustainable building materials by comparing locally grown eucalyptus with conventional construction materials.<\/p>\n

Students will examine factors such as structural performance, carbon emissions and local sourcing while participating in research that addresses Â鶹´«Ã½<\/span>\u2019s unique environmental and construction challenges. Many members of the research team are UH<\/abbr> students from Â鶹´«Ã½<\/span> who are helping develop solutions that could benefit the state\u2019s future infrastructure and economy.<\/p>\n","protected":false},"excerpt":{"rendered":"
