Two new approaches to management of solid tannery waste
Disposal of huge amounts of solid tannery waste is a formidable problem. In Bangladesh, the solid tannery waste has been
traditionally disposed off through landfills. Animal feed manufacturers somehow discovered the potential of these wastes
to be used in feeds because of their protein content. However, the possible transfer of the toxicity of this waste to common food
items like chicken, eggs and fish gave a scare after the publication of some research articles by a number of local scientists. This
created a hue and cry and eventually led to the ban on the use of tannery waste in poultry feed. The tannery industries will now
have to dump these wastes in properly-constructed expensive landfills. It is unfortunate that such a protein-rich resource is
being dumped rather than being utilized. This has prompted a group of scientists of the University of Northampton, England to
come forward with an elaborate procedure of removing chromium altogether from the solid waste before using it in the poultry
feed. We are proposing an alternative idea in which the formation of highly toxic Cr(VI) will be prevented by taking proper
steps at different stages of production of leather and feed. It is estimated that the amount of Cr(III) that enters chicken, eggs and
fish through the feed would cause no health risk to consumers. The second approach may be appropriate for Bangladesh. The
dumping of solid waste in landfills is not practicable and not in conformity with the present-day idea of industrial symbiosis.
