A joint research effort is being conducted on ways to produce cost-effective pulping catalysts from lignin. This project addresses improving selectivities and reducing the levels of sulfur chemicals used in pulping. Improved selectivity means an increase in pulping rate and yields, which translates to less energy required per ton of product. Less sulfur means a simplified process, lower odor emissions, and a decrease requirement for bleaching chemicals, meaning less organics being discharged to rivers
