Abstract


The exploitation of industrial waste oils and fats, along with the influence of physical, thermal, chemical and biological factors, is the reason for their transformation and formation of waste emulsions that pose a potential risk of environmental pollution. This paper provides an overview of reference technological processes which are considered as the sources of environmental pollutants. In addition, this study presents the qualitative and quantitative characteristics of aqueous emulsions of waste fats and oils from metal processing and thus proposes a system for treatment that would minimize the risk of environmental pollution.
