Catalytic Pulping of Wood
Snapshot: The kraft pulping process has been around for more than 100 years. It is cost effective and efficient but provides a low fiber yield and a complex and expensive chemical recovery process. Using oxygen activated by a transition metal catalyst has the potential to raise fiber yield significantly while decreasing chemical costs and environmental concerns.
