Canada created lab-grown wood that grows in sheets without cutting a single tree
In cutting-edge laboratories nestled in British Columbia, Canadian scientists have achieved a transformative breakthrough in sustainable materials science: wood grown entirely in lab conditions without requiring trees to be felled. This biofabrication process produces sheets of wood with customizable shapes, grain patterns, and mechanical properties, all grown from live plant cells cultured in controlled environments, effectively decoupling wood production from deforestation.
The process begins with isolating cambium cells—the vital growth tissue from tree trunks responsible for wood formation. These cells are embedded within nutrient-rich hydrogel matrices and stimulated with carefully timed pulses of growth hormones that replicate the natural signals trees receive during their development. Over a period of weeks, the cells proliferate and differentiate, synthesizing lignocellulose fibers that self-organize into dense, sheet-like structures mimicking the natural grain and texture of wood.
What sets this innovation apart is its ability to guide the wood growth spatially through 3D-printed scaffolds. This means wood can be “grown” into pre-designed shapes—planks, curved beams, or ornamental patterns—eliminating traditional cutting and machining steps that generate massive waste. One growth chamber can yield enough wood sheets to assemble entire furniture pieces or architectural panels within two months, offering a scalable alternative to conventional timber.
This lab-grown wood is not only sustainable but superior in several ways: it is fire-resistant, termite-proof, and exhibits carbon-negative properties by sequestering CO₂ throughout its growth cycle. It requires dramatically less water—up to 95% less—and no pesticides or fertilizers, making it environmentally friendly at every stage. Early pilot projects are already underway, incorporating this material into modular homes, public structures, and artisanal products like musical instruments.
The implications for global forestry are profound. By removing the need to cut living trees, this technology could drastically reduce habitat loss, protect biodiversity, and slow climate change. It signals a future where humanity harnesses the building blocks of nature directly, growing materials with precision and care rather than extracting and destroying.
