Imagine a future where buildings are lighter, more resilient, and built with a material stronger than steel yet derived from wood. InventWood’s Superwood is making this vision a reality, offering an unprecedented blend of strength, durability, and sustainability that could fundamentally transform how we build and furnish our world.
For decades, the quest for superior building materials has centered on metal alloys and composites. Yet, a breakthrough from Maryland-based InventWood is challenging these norms, leveraging one of nature’s oldest materials: wood. Introducing Superwood, a revolutionary material that promises to be up to 10 times stronger than steel by weight and an impressive six times lighter, fundamentally redefining the possibilities of construction and design.
The Genesis of a Game-Changer: Liangbing Hu’s Decade-Long Quest
The journey to Superwood began over a decade ago with material scientist Liangbing Hu. While working at the University of Maryland, Hu embarked on a mission to reinvent wood. His early experiments were nothing short of visionary, even including making wood transparent by removing parts of its lignin, the component responsible for its color and some of its strength.
However, Hu’s ultimate goal was to significantly enhance wood’s strength. The true breakthrough arrived in 2017. His method involved chemically treating regular wood to strengthen its natural cellulose – the most abundant biopolymer on Earth. This treated wood was then hot-pressed, collapsing its cellular structure and making it significantly denser. This intensive process resulted in a material with a strength-to-weight ratio surpassing that of most structural metals and alloys, a finding detailed in a landmark study published in the journal Nature.
After years of refinement and securing over 140 patents, Hu’s vision has culminated in InventWood’s commercial launch of Superwood from its plant in Frederick, Maryland.
Beyond Ordinary Timber: What Makes Superwood So “Super”?
What sets Superwood apart from traditional wood and other engineered timber products is its fundamental alteration at the molecular level. Unlike engineered woods that rely on adhesives to combine wood pieces, Superwood’s internal structure is reimagined. InventWood CEO Alex Lau emphasizes, “From a chemical and a practical standpoint, it’s wood… except it’s much stronger and better than wood in pretty much every aspect that we’ve tested,” as reported by CNN.
The practical benefits are staggering:
- Unmatched Strength: Up to 20 times stronger than regular wood.
- Enhanced Durability: 10 times more resistant to dents.
- Resilience: Impervious to fungi and insects, thanks to its collapsed and toughened porous structure.
- Fire Resistance: Scores the highest ratings in standard fire resistance tests.
- Versatility: The process has been successfully applied to 19 different wood species, including bamboo, showcasing its broad applicability.
Transforming Construction, Furniture, and Beyond
The implications of Superwood for the construction and design industries are profound. Alex Lau highlights the potential for buildings to be up to four times lighter, translating into structures that are more earthquake-resistant, easier on foundations, and faster to construct. This isn’t just about strength; it’s about reimagining the entire building process.
Initially, InventWood is targeting external applications like decking and cladding. However, plans for next year include expanding into internal uses such as wall paneling, flooring, and home furniture. Lau points out a common frustration addressed by Superwood: “People always complain that furniture breaks down over time… often because it sags or breaks down at the joints, which are currently made of metal because wood isn’t strong enough.” Superwood offers a viable, stronger, and lighter alternative to metal components like screws, nails, and joints in furniture, promising greater longevity and design freedom.
Ultimately, the vision extends to entire buildings constructed from Superwood, though this ambitious goal will require further extensive testing and regulatory adoption.
Sustainability at Its Core: A Greener Future for Materials
In an era demanding sustainable solutions, Superwood emerges as a compelling alternative to carbon-intensive materials like steel and concrete. While its manufacturing has a larger carbon footprint than regular wood, InventWood proudly states that its emissions are 90% lower than steel production. The company’s strategic goal isn’t to undercut the price of regular wood but to be cost-competitive with steel, emphasizing its long-term environmental value over immediate cost savings for basic timber.
The global construction industry is a significant contributor to carbon emissions, with concrete production alone generating 7% of the world’s global carbon emissions, according to Our World in Data. Timber construction has seen a resurgence, with wooden skyscrapers already rising in cities like Milwaukee. As Philip Oldfield, an architecture professor at the University of New South Wales, notes, timber stores CO2 in its woody biomass, acting as a long-term carbon storage system. This makes materials like Superwood vital in the push for green buildings.
Navigating the Future: Industry Adoption and Community Impact
While the technical prowess of Superwood is undeniable, its widespread adoption hinges on overcoming inherent industry challenges. Professor Oldfield highlights that the construction industry is notoriously risk-averse and slow to change. He suggests that fostering greater timber uptake will require significant investments in better education, extensive pilot projects, and robust regulatory support.
For our community, this innovation represents more than just a material; it’s a paradigm shift. Imagine the possibilities for DIY enthusiasts to build furniture that truly lasts generations, or for architects to design breathtaking structures with previously unimaginable spans and finishes. Superwood doesn’t just offer stronger wood; it offers a pathway to a more sustainable, resilient, and innovatively constructed future.
As InventWood scales up production, the real test will be how quickly the market embraces this “super” alternative. But one thing is clear: the era of wood competing directly with—and even outperforming—traditional metals is here.
