Various alkaline, semichemical, organosolv and other methods have been developed for non-wood pulping but many of them are tested only in laboratory environments. Paper I reviews in more detail the recent developments in the chemical and chemi-mechanical non-wood pulping processes and the advantages and disadvantages of these systems. No remarkable breakthrough has occurred in recent decades in the field of non-wood pulping, excluding the Chempolis and CIMV process development.
