Application

• The WoodZymes project develops extremophilic enzymes to improve kraft pulping, reducing chemical use and enhancing pulp brightness. It also valorizes lignin and hemicellulose to create sustainable products like polyurethane foams and phenolic resins, reducing environmental impact.

Description

The WoodZymes project focuses on developing novel biocatalytic technologies to reduce the environmental footprint of the pulp and paper industry. European researchers engineered extremophilic enzymes, such as xylanases and laccases, to break down lignin and hemicellulose under the harsh conditions of kraft pulping. These enzymes help valorize underused wood components, reducing the need for harmful chemicals like chlorine dioxide, and improving pulp quality and energy efficiency.

Pathway Description:

The WoodZymes project uses biocatalytic technology by developing and optimizing extremophilic enzymes that can operate under the harsh conditions of the kraft pulping process (high temperature and alkalinity). These enzymes, such as xylanases and laccases, break down hemicellulose and lignin in wood biomass, allowing for more efficient use of the wood components. The process improves pulp bleaching, reduces chemical usage
