Bleaching is one of the most chemical-intensive steps in pulp production, traditionally relying on chlorine-based chemicals that impact both cost and the environment. GEPZYMES PULPZ is a high-performance xylanase enzyme designed for the EOP stage (Extraction with Oxygen and Peroxide) in pulp bleaching. It selectively hydrolyzes hemicellulose-bound xylan, improving bleach chemical penetration and enhancing overall brightness, while reducing the need for chlorine-based chemicals.
