industries generate wastewater containing high concentrations of sulfur. Most
of wastes are liquid (effluent). The river section and tanning are the source
of most tannery waste. Dehairing is a process of separation of hair and
epidermis. Lime and sulfides are used for this process. Thus, sulfur in
wastewater dehairing occurs as sulfide. Today, catalysis is at the centre of
major societal concerns about energy, environment and sustainable development.
The discovery of new catalytic processes and the improvement of existing ones
are also critically important for improving the quality of life while
simultaneously reducing the adverse impact of human activities on the
environment. With a substitution approach of a catalyst MnSO4 by
multiple wastes from tannery and the metallurgical sector, this study
investigated the recycle of waste from dehairing process and waste from
metallurgical industry. The results indicated 32% of oxidized sulfur for the
first waste derived from process of depilation and 30% for the second waste
from metallurgical process industry. A preliminary cost analysis demonstrated
that the proposed solution is much cheaper than the discharging of waste and
wastewater in a WWTP; however, the sustainability of the proposed solution
provided a second alternative, to alleviate the operational costs of
installations wastewater from tanneries, without significantly impacting the
