OZONE APPLICATION IN THE LEATHER INDUSTRY

Abstract

Purpose. To generalize and systematize the information provided in the literature on the use of ozone
technologies in the production of natural leather, paying special attention to such key issues as more
rational use of material resources and reduction of harmful emissions into the environment.
Methodology. Analysis of scientific and technical literature, synthesis, comparison, generalization and
systematization of the obtained results.
Results. Based on the analysis and organization of information available in the scientific and technical literature, it has been established that ozone technology is one of the promising technologies that
can not only treat complex compounds present in industrial tannery wastewater, but also impart the
necessary properties to chemical and leather materials, thereby contributing to a more rational use
of material resources.
Scientific novelty. For the first time, information on the possibilities of ozone technologies in the leather
industry has been generalized and systematized, with the main areas of their application identified
for more efficient use of material resources while respecting the environment.
Practical value. The results of the study of developments in the use of ozone technologies in leather
production will contribute to the expansion of knowledge on improving methods for the production of
natural leather, as well as reducing the pollution of household and industrial wastewater.
