Inedible tallow

Colourless liquid. B.p. 286 C/100 mm., insoluble in water. Oleic acid occurs naturally in larger quantities than any other fatty acid, being present as glycerides in most fats and oils. It forms one third of the total fatty acids of cow s milk. A crude grade from inedible tallow is used in the production of lubricants, detergents, resins and other products.

Rendered beef, pork, poultry, and other animal fats are not well reported internationally, and global statistics are unreliable. Total production of fats in the United States by the rendering industry for 2000 is estimated at 4.18 million metric tons.68 Outputs of all rendering facilities captive to integrated broiler operations might not be included. Of the amount reported, 76 percent is inedible tallows and greases, 18 percent is edible beef or mutton tallows, and 6 percent is edible pork lard. 

Rendering produced an estimated 4.18 million metric tons of animal fats was produced in the United States in 2000 by rendering.87 Of this amount, approximately 18 percent and 6 percent were edible tallow and lard, respectively, and 41 percent and 35 percent were inedible tallow and grease. Approximately 15 percent and 34 percent of the edible tallow and lard, respectively, and 37 percent of the inedible tallow and grease were exported. Of the inedible tallow and grease used in the United States, an estimated 75 percent was used as animal feed, 16 percent was converted to fatty acids by the oleochemicals industry, 4 percent was used in soaps, and 3 percent in lubricants. Inedible animal fats are the lowest cost domestic fat sources. Their market price per pound sometimes is less than fuel oil, and rendering plants have chosen to bum them as fuels. In 2001, animal fats were included with vegetable oils for federally supported trials of biodiesel fuel.

For tallow, although industry identifies and trades in many grades of raw material, cumulative production and use data are listed in terms of only edible vs. nonedible tallow, at best. The United States accounts for approximately half of the annual world production of tallow, with the balance coming primarily from Australia, Canada, New Zealand, Argentina, and Brazil. In the United States, the production of inedible tallow typically is slightly more than double that of edible tallow. Thus, in the year 2000, the U.S. inedible tallow production was 1.7 million metric tons, and edible tallow production was estimated at 0.76 million metric tons (59). In the year 2000, estimated lard production, for use mostly in cooking, was estimated at... 

Grease production data are often lumped with that for inedible tallow. Greases constitute about 45% of this total and are used exclusively in nonedible applications. In the United States, the use of yellow grease in animal feeds is increasing yearly and in 2000 accounted for 36% of total feed fat usage (62).

Use of Domestically Produced Tallows. Currently, approximately 35% of domestically produced inedible tallow is exported, leaving about 2.7 million MT available for domestic use (1). Rouse (29) reported that domestic use of inedible tallow increased by 63%, from 0.81 million MT in 1950 to 1.3 milhon MT in 1991. In 1950, about 72% of the available domestic inedible tallow (0.58 million MT) was used in making soap and hardly any in animal feeds. With the development of synthetic detergents, the use of edible tallows in soap making dropped to 0.15 million MT or 12% of the total in 1991, and animal feeds rose to using about 62% of the domestic supply. 

Most deliveries of feeding fats are made by insulated tank truck, which allows users without raihoad sidings to be serviced, just-in-time deliveries, reduced numbers of local storage tanks, and rapid delivery while the fat remains hot. The industry and its contract haulers take pride in their equipment, and an inedible tallow tank truck looks little different from other milk or liquid ingredients trucks if kept clean.
