UBC Researchers Revolutionize Wood Durability with Plastination

URGENT UPDATE: Researchers at UBC Okanagan have just unveiled a groundbreaking method to enhance the strength and durability of Western red cedar using a technique traditionally employed for preserving human remains. This innovative application of plastination promises to significantly improve wood’s resistance to moisture damage and decay, addressing a critical challenge in sustainable construction.

In a study published in the journal Materials, the team successfully demonstrated that plastination can effectively replace water in the wood’s cellular structure with a silicone compound, creating a robust, hydrophobic barrier. This process not only enhances durability but also reduces water absorption by nearly 60 percent and increases surface hydrophobicity by more than 45 percent. The implications for construction materials are enormous, especially in North America where moisture resistance is vital.

Doctoral student Olivia Margoto, part of the research team, emphasized the importance of this technique: “By applying plastination, we’re preserving the wood’s structure from the inside out, maintaining its strength while dramatically improving its resistance to water.” This innovation could revolutionize how building materials are treated, moving away from conventional methods that often involve toxic chemicals.

The process begins with dehydrating the wood using acetone, followed by infusing it with a compatible polymer. This unique approach preserves the anatomical architecture of the wood while enhancing its flexibility and strength. Study supervisor Dr. Abbas Milani noted that plastination offers a significant advantage over traditional wood preservatives that rely on short-lived coatings.

Supporting this research is NetZero Enterprises Inc., a Penticton-based company that holds patents for the plastination technique in Canada and the U.S. The collaboration aims to further explore the scalability of this method and investigate the use of bio-based polymers to further reduce environmental impacts. CEO Grant Bogyo of NetZero commented on the potential of this technology to extend the lifespan of natural wood products without compromising environmental performance.

The application of plastination to Western red cedar is particularly promising due to its unique microstructure, which is significantly different from the bamboo previously studied. This advancement not only highlights the versatility of plastination but also opens new avenues for sustainable development in construction.

Future research will delve into optimizing the method and recovering solvents used in the process. The team is committed to ensuring that the natural materials provided by nature are utilized in a safe, sustainable, and economical manner.

As the world continues to seek innovative solutions to climate change and sustainability challenges, UBC Okanagan’s research stands at the forefront of a potential revolution in material science. The findings not only represent a significant leap for building materials but also embody the spirit of innovation and environmental stewardship.
