Abstract The processing of raw hides and skins generate large quantities of solid wastes, which are conjugates of protein with carbohydrate and fat. A survey was conducted from 1993 -1995 in 91 tanneries around Chennai to evaluate the availability of these solid wastes. The survey showed that 150 tons of limed fleshings and 2448 tons of chrome shavings were produced in 91 tanneries during 1994–95. An estimate suggests that 140 tons of fleshings, 60 tons of chrome shavings and 40 tons of trimmings are generated per day in Tamil Nadu. The utilization of these wastes have great significance in the environmental perspective. The limed fleshings can be converted into fleshing meal, trimmings into dog chews and chrome shavings into leather meal. Since the raw by-products of these meals are available in large quantities in tanneries, it is recommended that they may be incorporated as dietary source of animal protein in the poultry feeds.
