Excerpts from the report Preface: This report represents the first comprehensive study of wool grease recovery and use in the United States. The Wool Advisory Committee, one of the industry advisory groups established under the Research and Marketing Act of 1946 to advise the Department on its research program, recommended in 1947 that one phase of the Department's wool research program be devoted to an economic appraisal of the scouring, recovery, refining, and distribution of wool grease and other byproducts of the wool manufacturing industry. This report is an outgrowth of the above recommendation and deals with the economic aspects of the production, distribution, and consumption of wool grease. In this report, the marketing channels and functions as well as the structure and characteristics of the wool grease industry are described and analyzed in some detail. Grease production by the wool scouring industry and the competitive situation of the product relative to other fats and oils made it necessary to discuss the economic and technical aspects of its production and consumption.
