Biopulping process
WebPulping and Bleaching Processes Pulp is produced from wood by either chemical delignification, mechanical separation of the cells (fibers), or combinations of chemical and mechanical methods. Mechanical pulping methods give much higher yields (80–95% based on the wood) than the chemical methods (40–50% yields).
