Abstract

The composition complexity and proven toxicity of olive oil mill wastewater (OOMW) poses a significant danger to all environmental components. A disposal of such water is very specific and complex, and regularly requires a combination of different treatment procedures, which results in significant financial costs. However, by implementing a suitable technology, OOMW can be converted into products with a high added value, thus making it less toxic and more easily treatable. The paper summarizes new insights into the OOMW evaluation, with over 95 references that can be used as a basis for further investigations in this field and a potential commercial application. Two main approaches to wastewater evaluation are presented: the isolation of biologically active compounds from OOMW and the processes of bioconversion of substances present in wastewater into highly valuable compounds. Recycling of “waste” substances from olive processing is in line with the global trends of environmental protection and transformation of waste into useful products that can be used in agriculture, chemical, textile, pharmaceutical and food industries.
