NextFin news, On October 14, 2025, InventWood, a US-based startup headquartered in Frederick, Maryland, officially launched Superwood, a revolutionary engineered wood product designed to transform the construction industry. Developed over more than a decade by materials scientist Liangbing Hu, now a Yale professor, Superwood is chemically treated and densified wood that achieves a strength-to-weight ratio up to 10 times greater than steel, while being up to six times lighter. This breakthrough was achieved by enhancing cellulose—the most abundant biopolymer on Earth—through a patented process involving lignin removal and hot-pressing, resulting in a wood material that is up to 20 times stronger and 10 times more dent-resistant than conventional wood.
InventWood CEO Alex Lau, who joined the company in 2021, emphasized that Superwood maintains the natural look and feel of wood but significantly outperforms traditional timber in strength, durability, and resistance to fire, insects, and fungi. The company currently manufactures Superwood in Maryland, with production times reduced from days to hours, and plans to initially target exterior applications such as decking and cladding, expanding to interior uses like flooring and furniture by 2026. While Superwood currently carries a higher cost and carbon footprint than regular wood, its manufacturing emissions are approximately 90% lower than steel production, aligning with growing sustainability demands in construction.
The development of Superwood traces back to Hu’s research at the University of Maryland’s Center for Materials Innovation, where he pioneered methods to chemically treat and densify wood at the molecular level. Published in the journal Nature in 2017, this research demonstrated that treated wood could surpass many structural metals in strength-to-weight ratio, opening new possibilities for timber in high-performance construction.
Superwood’s emergence comes amid a resurgence in timber construction, with cities like Milwaukee pushing the boundaries by planning skyscrapers up to 600 feet tall using engineered wood. Concrete remains the dominant construction material globally, responsible for approximately 7% of worldwide carbon emissions, but innovations like Superwood offer a pathway to reduce this environmental impact by substituting steel and concrete with sustainable, high-strength timber alternatives.
From an industry perspective, Superwood addresses critical challenges in construction materials: reducing structural weight, enhancing earthquake resistance, and improving durability without compromising aesthetics. Its superior strength-to-weight ratio could enable architects and engineers to design larger spans and lighter foundations, potentially lowering construction costs and timelines. Moreover, its resistance to fire and biological degradation enhances building safety and longevity.
However, widespread adoption faces hurdles including higher initial costs, scaling manufacturing capacity, and overcoming the construction sector’s inherent risk aversion and regulatory inertia. Lau notes that education, pilot projects, and updated building codes will be essential to accelerate market penetration. As production scales and processes optimize, InventWood aims to price Superwood competitively with steel, targeting markets where performance and sustainability justify premium materials.
Looking forward, Superwood exemplifies a broader trend toward bioengineered materials that combine natural resources with advanced processing to meet modern infrastructure demands. Its success could catalyze further investment in cellulose-based composites and sustainable construction technologies, aligning with President Donald Trump’s administration’s infrastructure modernization goals and environmental policies emphasizing innovation.
In conclusion, InventWood’s Superwood represents a paradigm shift in construction materials, merging the ecological advantages of wood with performance metrics that rival steel. This innovation not only promises to reduce the carbon footprint of buildings but also to redefine structural engineering possibilities, signaling a transformative era for the global construction industry.
According to GreekReporter.com, InventWood’s Superwood is poised to become a cornerstone material in future sustainable construction, with its unique combination of strength, lightness, and environmental benefits setting new industry standards.
