11. With almost twice the yield as chemical pulping , mechanical pulps is often cheaper. 12. Silica is problematic as it consumes pulping chemicals and produces fly ash when burned. 13. Organosolv has several advantages when compared to other popular methods such as sulfite pulping . 14. Caustic soda is added to increase the pH in the pulping process of fibers. 15. Acidic pulping processes shorten the cellulose chains. 16. These hybrid methods include thermomechanical pulping ( TMP ) and chemithermomechanical pulping ( CTMP ). 17. These hybrid methods include thermomechanical pulping ( TMP ) and chemithermomechanical pulping ( CTMP ). 18. Recycling of water in the de-pulping process can drastically reduce the amount needed. 19. The main component is organic matter, stemming from de-pulping and mucilage removal. 20. To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres.
