Ozonolysis of Lignin: From Extensive Degradation to Selective Ring‐Opening Oxidation
Despite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.

Manufacturing process and mechanical testing of lignin polymer composites. ABSTRACT Lignin is a plant‐derived, the second most abundant natural polymer, and a waste byproduct of the pulp industry. Incorporation of lignin into plastic composites using scalable approaches is commercially favored and low carbon‐cost.

A wood‐form‐stable phase change composite featuring a tensile strength of 134.42 MPa, zero leakage under load, and a phase change enthalpy of 94.73 J g−1 is developed through a structural biomimicry and dual‐network reinforcement strategy. With its exceptional shape stability and remarkable phase change performance, this phase change composite is well ...

Mill experience of oxygen delignification.
The M-C oxygen delignification system for the eucalyptus line of our mill has started operation in January 1986.The Kappa number and viscosity reduction are around 49 % and 19% respectively.Also, the good results are shown in terms of brightness and dirt content.Whereas, the reduction of total effective chlorine consumption and COD in the bleaching ...
