1916 United States Department of Agriculture (USDA) chief scientists Jason L. Merrill and Lyster H. Dewey created paper made from hemp pulp, which they concluded was "favorable in comparison with those used with pulp wood" in USDA Bulletin No. 404. From the book "The Emperor Wears No Clothes" by Jack Herer the USDA Bulletin N. 404 reported that one acre of hemp, in annual rotation over a 20-year period, would produce as much pulp for paper as 4.1 acres (17,000 m2) of trees being cut down over the same 20-year period. This process would use only 1/7 to 1/4 as much polluting sulfur-based acid chemicals to break down the glue-like lignin that binds the fibers of the pulp, or even none at all using soda ash. The problem of dioxin contamination of rivers is avoided in the hemp paper making process, which does not need to use chlorine bleach (as the wood pulp paper making process requires) but instead safely substitutes hydrogen peroxide in the bleaching process. ... If the new (1916) hemp pulp paper process were legal today, it would soon replace about 70% of all wood pulp paper, including computer printout paper, corrugated boxes and paper bags. However, mass production of cheap news print from hemp had not developed in any country, and hemp was a relatively easy target because factories already had made large investments in equipment to handle cotton, wool, and linen, but there were relatively small investments in hemp production.
