CMP and CTMP of a fast-growing tropical wood: Acacia mangium

Pulping characteristics of young plan- tation-grown Acacia mangium were investigated using alkaline sulfite chemimechanical pulping (CMP) and chemithermomechanical pulping (CTMP). Results were compared with those obtained from Canadian aspen, birch, and maple pulped under simi- lar conditions. In general, A. mangium produced pulps that were compara- tively inferior in physical and optical properties compared to those made from Canadian hardwoods. It was found that the CMP effluent from A. mangium was particularly high in solids content, total organic carbon, chemical oxygen demand, and toxicity with respect to the Canadian hard- woods studied.
