The level of the environmental impact of olive oil production in Palestine was evaluated by measuring the parameters: pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), the concentration of fat; oil, and grease (FOG), phenols, electric conductivity (EC) total phosphorus (T-P), and total Kjeldahl nitrogen (TKN, and compared with the Jordanian standard values. The results show that the value of these parameters are too high. A local survey has also been conducted by designing a questionnaire that covers oil production yield, water consumptions in olive washing and in oil recovery, wastewater generation relative to olive processed and oil generated, and solid waste product: The data were collected from 92 local olive oil mills, which were analyzed and organized according to the investigated parameters, and categorized according to local selected areas in the West Bank such as Hebron (South), Nablus (Center) and Jenine (North). The results revealed local variations in oil yield and solid waste product due to variations in the type of olive produced. The olives from the South were found to contain larger solid content than those from the North, .resulting in lower oil yield. The overall results indicated that the average oil yield was 23.7%, the solid waste product was 40.0% while the remaining balance was. the water. content (36.7%) in the olive fruit. A representative value at 1.7 m3/ton for wastewater generation was found to be high compared to similar values in other places of the world. This requires a criterious review of the technology and operation of olive mills in Palestine. The characteristics of OMW were found to violate the standards for OMW and this requires the attention of authorities.

Olive pomace is a semisolid by-product of olive oil production and represents a valuable source of functional phytocompounds. The valorization of agro-food chain by-products represents a key factor in reducing production costs, providing benefits related to their reuse. On this ground, we herein investigate extraction methods with supercritical carbon dioxide (SC-CO2) of functional phytocompounds from olive pomace samples subjected to two different drying methods, i.e., freeze drying and hot-air drying. Olive pomace was produced using the two most common industrial olive oil production processes, one based on the two-phase (2P) decanter and one based on the three-phase (3P) decanter. Our results show that freeze drying more efficiently preserves phytocompounds such as α-tocopherol, carotenoids, chlorophylls, and polyphenols, whereas hot-air drying does not compromise the β-sitosterol content and the extraction of squalene is not dependent on the drying method used. Moreover, higher amounts of α-tocopherol and polyphenols were extracted from 2P olive pomace, while β-sitosterol, chlorophylls, and carotenoids were more concentrated in 3P olive pomace. Finally, tocopherol and pigment/polyphenol fractions exerted antioxidant activity in vitro and in accelerated oxidative conditions. These results highlight the potential of olive pomace to be upcycled by extracting from it, with green methods, functional phytocompounds for reuse in food and pharmaceutical industries.

The annual olive oil production in Cyprus is in the range of 2700–3100 t y−1, resulting in the generation of significant amount of waste. The cocomposting of the olive oil solid residue (OOSR) and the treated wastewaters (with Fenton) from the olive oil production process with the application of reed beds has been studied as an integrated method for the treatment of wastewater containing high organic and toxic pollutants under warm climate conditions. The experimental results indicated that the olive mill wastewater (OMW) is detoxified at the end of the Fenton process. Specifically, COD is reduced up to 65% (minimum 54.32%) by the application of Fenton and another 10–28% by the application of red beds as a third stage. The final cocomposted material of OOSR with the treated olive mile wastewater (TOMW) presents optimum characteristics and is suitable for agricultural purpose.
