Abstract
ABSTRACT
The opportunities for recovery of chromium(III) in cattlehide tanneries were investigated by reviewing the recent literature on chromium recovery techniques, performing an intensive sampling and analysis program in such a plant, and conducting a series of laboratory treatability studies. It was concluded that direct reuse of spent tanning liquours provided the most cost-effective means of recovering soluble chromium from this source. Recovery from solid waste streams, such as shavings and trimmings waste, is feasible using incineration. The cost-effectiveness of this approach will depend upon numerous external factors, however.
