Scientists have got to get inventive when it comes to creating sustainable construction materials that address carbon dioxide emissions because the world is so focused on combating climate change.
Scientists have now developed a new method of strengthening wood and capturing carbon dioxide from the atmosphere.
It is well acknowledged that carbon dioxide is a major cause of climate change. A strategy to indirectly combat climate change is to restrict the carbon dioxide emissions brought on by the manufacturing of structural elements like steel, metal, and cement.
Reducing atmospheric carbon dioxide by storing it in structural materials is a direct strategy.
Scientists That Made CO2 Emissions Capturing Wood
Researchers at Rice University in Texas have taken advantage of wood’s inherent qualities to improve its capacity to absorb carbon dioxide.
When the internal framework has been removed, the method entails adding highly porous microparticle metal-organic frameworks (MOFs) to the wood. Delignification is the process in question.
“Wood is made up of three essential components: cellulose, hemicellulose and lignin,” said Muhammad Rahman, corresponding author of the study. “Lignin is what gives the color, so when you take lignin out, the wood becomes colorless.”
The wood is prepared to accommodate the MOF once it has undergone delignification.
Soumyabrata Roy, a research scientist at Rice University and the study’s principal author, said of the MOF particles, “The MOF particles easily fit into the cellulose channels and get attached to them.” Then, the CO2 is absorbed by the MOFs.
MOFs are not well recognized for being stable in a variety of environmental circumstances. They frequently exhibit moisture sensitivity, which is something that should be avoided in a structural material.
Yet in their research, the Rice team discovered that the MOF they employed, created by Professor George Shimizu and his associates at the University of Calgary, outperformed others in terms of performance and adaptability under diverse circumstances.
The modified wood was shown to have greater resistance to environmental stressors like bending and stronger tensile properties than regular, untreated wood.
Additionally, they assert that the wood was produced using a potentially scalable and energy-efficient procedure.
Due to the fact that buildings account for more than 40% of all human-produced greenhouse gas emissions, this finding may lead to more environmentally friendly building practices. One that is renewable and sustainable.
The research was released in the journal Cell Reports Physical Science.
