Researchers at the University of Maryland have developed genetically modified poplar trees that can produce high-performance structural wood without the need for chemicals or energy-intensive processing. This engineered wood, known as Engineered wood, is considered a renewable alternative to traditional building materials like steel, cement, glass, and plastic. It has the added benefit of potentially storing carbon for longer periods due to its resistance to deterioration.

The traditional method of producing engineered wood involves using volatile chemicals and a significant amount of energy, leading to waste production. However, by editing one gene in live poplar trees, the researchers were able to grow wood that is ready for engineering without the need for processing.

Published in the Journal Matter, this innovative approach combines genetic engineering and wood engineering to create a sustainable form of super wood that can sequester and store carbon efficiently. This has significant implications for combating climate change and can have various uses in the bioeconomy.

The genetically modified poplar trees have a lower lignin content, similar to chemically treated trees used in engineered wood production. These trees showed no difference in growth rates or structure compared to unmodified trees, demonstrating their viability.

By producing compressed wood samples using the genetically modified poplar, the researchers found that it performed as well as chemically processed natural wood. The compressed wood had increased density and strength, comparable to aluminum alloy 6061. This research offers a cost-effective and environmentally sustainable method of producing building products that can contribute to the fight against climate change.
