Paper pulps were prepared from Gamar (Gmelina arborea, Roxb.) wood of four age groups by the Kraft process, Cooks were made with active alkali and sulfidity ranging from 14.94 percent to 21.05 percent and 14.12 percent to 20.12 percent respectively at 170 degrees Centigrade. The best pulp was obtained with 16 years old gamar wood at 14.94 percent active alkali and 14.57 percent sulfidity under optimum condition. Pulp yield varied from 40.86 percent to 49.35 percent at various ages. The physical strenght and other properties of Gamar Kraft pulp compared favourably with those of other hardwood pulp prepared in the Forest Research Institute, Chittagong.
