“…Furthermore, olive mill wastewater (OMW) is usually produced during the processing of olives and is considered the most pollutant containing wastewater constituted by up to 100,000 mg/L COD. This type of wastewater is characterized by a strong, intensive black color, acidic pH, a strong odor, and toxicant concentration in the range of 200-800 mg/L in the form of polyphenols [89] while possessing differentiated values of electro-conductivity [90].…”

In recent years, there has been a significant accumulation of waste in the environment, and it is expected that this accumulation may increase in the years to come. Waste disposal has massive effects on the environment and can cause serious environmental problems. Thus, the development of a waste treatment system is of major importance. Agro-industrial wastewater and waste residues are mainly rich in organic substances, lignocellulose, hemicellulose, lignin, and they have a relatively high amount of energy. As a result, an effective agro-waste treatment system has several benefits, including energy recovery and waste stabilization. To reduce the impact of the consumption of fossil energy sources on our planet, the exploitation of renewable sources has been relaunched. All over the world, efforts have been made to recover energy from agricultural waste, considering global energy security as the final goal. To attain this objective, several technologies and recovery methods have been developed in recent years. The microbial fuel cell (MFC) is one of them. This review describes the power generation using various types of agro-industrial wastewaters and agricultural residues utilizing MFC. It also highlights the techno-economics and lifecycle assessment of MFC, its commercialization, along with challenges.

“…36 In this case, use of membrane module is a good technique for recovering the phenols due to their low cost and low consumption of energy. 37 Furthermore, this technique not only recovers the phenols but also produces them with the required degree of purity. 38 From the industrial point of view, there is another interesting technique to recover phenols, the adsorption technique or the chromatographic technique.…”

“…These types of techniques can be classified into pressurized liquid extraction, high-pressure high-temperature, subcritical water extraction or superheated water extraction, supercritical fluid extraction, molecular distillation or short-path distillation, ultrasound-assisted extraction, microwave-assisted extraction, chromatographic methods or membrane 36 . In this case, membranes are a good technology to perform the recovery of the phenols due to its low cost and low consumption of energy 37 . Furthermore, this technology does not only recover the phenols but produces them with the proper degree of purity 38 .…”

A multi-stage multilayer systematic procedure has been developed for the selection of the optimal product portfolio from waste biomass as feedstock for systems involving water-energy-food nexus. It consists of a hybrid heuristic, metric based, and optimization methodology that evaluates the economic and environmental performance of added value products from a particular raw material. The first stage preselects the promising products. Next, a superstructure optimization problem is formulated to valorize or transform waste into the optimal set of products. The methodology has been applied within the waste to power and chemicals initiative to evaluate the best use of the biomass residue from the olive oil industry towards food, chemicals and energy. The heuristic stage is based on literature review to analyze the feasible products and technologies. Next, simple metrics have been developed and used to preselect products that are promising. Finally, a superstructure optimization approach is used to design the facility that processes leaves, wood chips and olives into final products. The best technology to recover phenols from "alperujo", a wet solid waste/byproduct of the process, consists of the use of membranes, while for the recovery of phenols from olive leaves and branches adsorption is the selected one. The investment required to process waste adds up to 110.2 million € for a 100 kt/yr of olives production facility while the profit depends on the level of integration. If the facility is attached to an olive oil production installation, the generated profit ranges between 14.5 MM €/yr (when the waste is purchased at prices of 249 € per tonne of alperujo and 6 € per tonne of olive leaves and branches) and 34.3 MM €/yr, when the waste material is acquired for free.
