“…The majority of the recorded papers concern olive oil production in Spain (32 papers; 28.8%), Italy (26 papers; 23.4%) and Greece (22 papers; 19.8%) (Fig. b), which is based on the fact that the aforementioned countries are the largest olive oil producers …”

The production of olive oil is considered to be one of the largest agricultural business sectors in the Mediterranean area. Apart from its significant impact on the economies of countries in Southern Europe, Northern Africa and Middle East, olive oil production also involves considerable social and environmental considerations. However, despite such importance, the environmental effects of olive oil production have not been studied as much other agricultural productions and farming systems, which are more characteristic of central and northern Europe. We present a thorough and systematic literature review of scientific publications with respect to the use of environmental tools in the life cycle of olive oil. The analysis takes into consideration the farming of olive trees, the manufacture of olive oil, packaging, transportation and reverse logistics. To that end, journal publications up to 2015 in this specific field are recorded and, at the same time, the most important environmental impacts are revealed and a gap analysis is carried out. The analysis conducted reveals that farming of olive trees (with pesticide use and waste/by-product production being the 'hottest' topics) and the manufacturing of olive oil (concentrating mostly on waste/by-product production and management) are the phases with the highest environmental focus from the scientific community. Moreover, gaps in the literature are detected mostly with respect to fuel consumption and the use and promotion of renewable energy sources in olive oil production. © 2016 Society of Chemical Industry.

“…The chemical composition of OMW is highly variable depending on various factors, such as the olive type, the geographical and climatic conditions, the tree age, the cultivation system, the degree of maturity of the fruit, the type of oil extraction process applied, the use of pesticides and fertilizers, etc. (Kallel et al, 2009;Yay et al, 2012). More specifically, OMW contain significant amounts of suspended, dissolved and colloidal matter were also relatively high as compared with most industrial effluents.…”

Olive oil extraction processes generate three phases: Olive oil, solid residue (pomace) and aqueous liquor Olive Mill Wastewater (OMW). OMW causes serious environmental deteriorations such as coloring of natural waters, alteration of soil quality, phytotoxicity and odor nuisance. The direct discharge of this effluent into the soil bring various negative effects on the environment, due to its high load of organic matter and phenolic compounds. Coagulation, flocculation and their combination processes are among the most applied processes for wastewater treatment. The application of coagulation technique using mineral and inorganic polymeric coagulants and acid cracking is not always effective to reduce COD and phenolic compounds from OMW except lime. Although direct flocculation is a low treatment cost, use less chemical and produce less sludge, the efficiency of COD and phenolic compounds removal remain very low. Coagulationflocculation process is developed in order to enhance the removal efficiency of organic matter from OMW by optimizing the operating conditions. However, many studies showed that the combination of various cationic organic coagulant and flocculant agents did not show any significant decrease of COD and phenolic compounds except for lime combination. In the present review, recent research studies dealing with the application of coagulation/flocculation for removal of phenolic compounds and COD from OMW are presented and compared. Furthermore, the main factors that influence the selection between coagulation, direct flocculation and coagulation-flocculation are presented and the principal removal mechanisms are discussed.

“…The industrialization of agricultural products produced thousands of tons of waste, taking a special interest the vegetable materials, due to their many potential uses, including the production of composite materials in structural applications Matos et al (2010). This is the case of waste from olive industry which also has the characteristic of being highly polluting and difficult to treat for disposal Caputo et al (2003), Suna Erses Yay et al (2012, Inan et. al.…”
