Shelter is an issue that indirectly affects many of the problems we experience in our age. The two basic materials we use to build the houses we live in today are cement and steel. While cement production causes global warming by causing high carbon dioxide emissions, there is a problem in the steel industry such as limited resources. Once the houses are built, the heating and cooling of the houses consumes a lot of energy and cannot be carried out efficiently enough.
Studies on these issues are underway. These studies include a variety of initiatives, from passive cooling to changing the chemical formula of cement. Now a sizable team of researchers in the US has developed a sustainable material that both reflects sunlight and sheds excess heat. An alternative solution has been produced with this material, which is produced by deactivating one of the two basic components of wood.
Wood is usually a combination of two polymers. One of them is the cellulose we know. Cellulose, like almost all structures ending in the name oz, is a sugar structure, a long sugar chain. The other polymer is lignin. Lignin is not essentially a single polymer, its chemical formula can vary widely.
Lignin is extracted from wood in a new chemical structure. Although the process is not fully specified, according to the contents of the article, wood is thrown into hydrogen peroxide and boiled. Although hydrogen peroxide is not the safest chemical in the world, it is a fairly simple substance to control and work with.
The resulting wood is then compressed and the sugar structures are put together in such a way that they can be bonded with each other. Thus, a tree that is stronger than any other tree structure emerges.
On the other hand, this newly released material has the strength to be used in places where wood cannot normally be used, thanks to its durability. Even though it’s not very good at catching sunlight, that doesn’t mean that the structures in which the newly discovered wood will be used will always be cold. This structure, which reflects the excess of the incoming heat back during the day, helps to preserve the heat inside at night.
Structures made of this material were used in simulations with historical weather data from various states of the USA. As a result, while 35% less energy was consumed in cooling the houses, this rate exceeded 50% in densely populated areas.
Although trees seem to be endangered for the production of this material, with the right planning, the production of this material will become very sustainable.
