The Revolution In Civil Construction Has Already Begun! Superwood, The Ultra-Resistant Wood That Promises To Replace Steel And Concrete And Help Reduce Up To 2 Gigatons Of CO₂.
Imagine a wood so strong that it can compete with steel, but with a much smaller carbon footprint. Sounds like science fiction? Well, this material already exists and is about to hit the market. Its name is Superwood and it has everything to change the future of civil construction.
The “Wood Of The Future” Is Coming Out Of The Laboratory
It all started with a challenge: how to make wood an ultra-resistant and sustainable material for large-scale structural use? The answer came from the research of scientist Liangbing Hu from The University Of Maryland, who has been developing innovative processes for years to enhance the natural properties of wood.
The secret of Superwood lies in its extreme densification. After partial removal of lignin with products such as sodium hydroxide and sulfite, the cellulose fibers are aligned and compacted under high pressure and temperature. The result is a material that is up to ten times more impact-resistant than original wood and has a tensile strength 50% greater than that of steel, according to a study published in Nature journal.

Additionally, Superwood exhibits excellent resistance to fire, decomposition, and pests—a major improvement over conventional wood, which requires chemical treatments to achieve these properties.
Startup Bets On The Global Market And Promises To Revolutionize Civil Construction
Behind the large-scale commercial production is the startup InventWood, licensed to explore the technology. The company has already raised over US$ 50 million in investments from funds such as Grantham Foundation and Builders Vision, and plans to start its first commercial shipments in the third quarter of 2025, as revealed by CEO Alex Lau in an interview with Fast Company.
The initial focus will be on exterior and interior cladding for residential and commercial buildings. The material offers not only high mechanical performance but also a sophisticated visual finish: during the compression process, the natural pigments of the wood intensify, creating an appearance similar to precious tropical woods like ipe and walnut, without the need for artificial staining.
“We believe this material can replace up to 80% of the steel used globally in certain structural applications, which would result in an estimated reduction of up to 2 gigatons of CO₂,” said Lau. The company emphasizes that all raw materials used will come from sustainably managed American forests, reinforcing commitment to a reduced carbon footprint.
Path To Replace Steel And Concrete
The team’s major goal is to go beyond cladding and develop a complete line of structural products—including beams, columns, and supporting elements—capable of directly competing with steel and concrete in civil construction.
According to Paul Hawken, author of the book Drawdown on climate solutions, “Materials like Superwood offer a concrete opportunity to transform the way we build entire cities, drastically reducing emissions associated with the construction sector.”
For now, InventWood’s production capacity is in a scaling phase, with a pilot plant located in Frederick, Maryland. But the potential is huge: it is estimated that the global low-carbon construction materials market could exceed US$ 1 trillion in the coming years, driven by new regulations and demand from architects and engineers committed to sustainability.
Stronger, Lighter, Greener
The numbers are impressive:
- 10x more impact-resistant than regular wood;
- 50% more tensile strength than steel;
- High durability against fire, decomposition, and pests;
- Premium visual without the need for painting;
- Renewable raw material and sustainable management;
- Drastic reduction in carbon footprint compared to steel and concrete.
Superwood is an example of how materials science is revolutionizing traditional industries. If InventWood’s plans materialize, we could see entire buildings erected in the coming years with this new type of wood—stronger than steel and much friendlier to the planet.
