Obtaining new tanning compounds based on titanium recovered from solid waste

The leather industry has to cope nowadays with major environmental problems because of the polluting technological processes. Therefore, increasing the environmental efficiency in the leather sector is the major aim of leather, auxiliary materials and equipment manufacturers. This new concept is trying to unify new processing rules leading to the harmonization of economic performance of the manufacturing units with the human and environmental protection criteria. An environmentally efficient technological process has to minimize the raw materials used meet the user' requirements, and minimize emissions. This study proposed the implementation of eco-friendly technologies for the processing of natural leathers, having as starting point a series of new tanning auxiliary materials, cheap and effective, obtained by means of processing solid waste titanium that cannot be recycled in the industry that produced them.
