In a conventional chemical bleaching process in the pulp and paper industry, a large volume of chemicals is used, releasing pollution into the environment. The new biobleaching process using enzymes leads to a significant reduction of chlorine and chlorine-based compounds. The xylanase attacks hemicellulose and alters the interface between the cellulose and lignin, thereby facilitating the chemical extraction of lignin from pulp.
ENZbleach has been developed and optimized for pulp biobleaching without the need of pH adjustment of the pulp, which will make the large-scale operations more simple and cost effective. Moreover, ENZbleach is a cellulose-free xylanase, thus does not destroy the structure of cellulose and diminish pulp quality.
