Current Landscape: Use of Supercritical CO ₂ in the Wood Industry

Wood has long been applied as a component in the development of housing, as well as providing useful compounds which are used in pharmaceuticals, agrifoods, and cosmetics. In recent times, its applicability in various industries continues to increase as more building takes place, along with the continual search for greener and more natural therapies. Currently, energy‐intensive processes are the driving force in the preparation of these wood samples. This review summarizes our current understanding of wood processing and its various applications. Additionally, this review focuses on the substitution of these energy‐intensive approaches with greener and more efficient techniques, which include the usage of supercritical fluids such as supercritical carbon dioxide (scCO 2 ). The use of scCO 2 has been documented to successfully dewater as well as perform resin extraction of various species of wood, more specifically, pine.
