The commercial Gold Soda Process for wood is relatively new pulping process developed at the United States Forest Products Laboratory in Madison, Wisconsin, for high-yield pulping for hardwoods.
The development of this process has been due to the increasing shortage of softwood fibers has made necessary the need for a suitable process for pulping hardwoods. The Gold Soda process is thought to meet some of the economic and strength requirements of this need.
Most of the research done on this subject has been done in the 65 to 95 yield range at the Forest Products Laboratory. This naturally follows from the fact the the Gold Soda process is a high-yield process and almost all interest to date has been in this range.
It should be noted that the few articles published have been concerned almost wholly with strength and economic characteristics, which are of primary concern to industry. Only one article has shown the effect of the process on chemical composition of the pulp.
