Enzymatic hydrolysis to produce nanocellulose in an integrated forest biorefinery strategy. A reviewIntroduction. In a world that seeks to break free from petrochemicals, the concept of forest biomass biorefinery is increasingly being studied as a way to maximize the value of the components of this biomass. Due to the high added value expected when transforming cellulose fibers into nanocellulose, this technology is highly attractive to the pulp and paper industrial world.Literature. The concept of integrated forest biorefinery is to adapt existing pulp mills so as to maximize the value of the co-products. Through the use of various methods, two types of nanocellulose may be obtained from the cellulose in the pulp. Due to its production of valuable byproducts, enzymatic hydrolysis is an interesting method to use for this purpose, but it must be combined with mechanical post-treatments. The production of nanocellulose from chemical pulp takes place in the final step of pulp production, and could be implemented without modifying the existing mills. The economic viability of this mode of production and the potential market size are the subject of recent studies that appear encouraging.Conclusions. Nanocellulose is a promising biomaterial whose field of application continues to grow. Cellulose in wood pulp can be used as a raw material for the production of nanocellulose using enzymatic pre-treatments that generate valuable co-products. This process can be integrated into a conventional chemical pulp mill and constitutes a broadening of the products available to the pulp and paper industry.
