Olive mill wastewaters decontamination based on organo-nano-clay composites

2019

Abstract Green composites for environmental applications were successfully prepared by intercalation of the biosurfactant Quillaja saponin onto montmorillonite mineral clay on varying pH and surfactant/clay ratio. Equilibrium adsorption isotherms were constructed and the system was characterized by performing TGA and XRD analyses. The efficiency of the surfactant-modified clay in the removal of the organic content present in olive mill wastewaters (OMW) was evaluated by means of spectrophotometric measurements. The interest for this cogent issue comes from the consideration that, despite their high pollutant content, OMW can be considered as a potential resource of several organic compounds…

Plants for Environmental Protection

2023

Plants for environmental protection are Anaerobic Digestion plants for converting biomass as Renewable Energy Source (RES), i.e. biowaste, agricultural feedstock, livestock effluents (manure and slurry) and food industry by-products, into biogas, i.e. bioenergy, as well as digestate, i.e. biofertiliser. In turn, biogas can be converted into electrical and thermal energy or can be used for extracting biomethane, i.e. biofuel, or can be injected in the natural gas grid. Moreover, digestate can be divided into solid and liquid fractions, that can be used for fertilisation or fertirrigation, respectively, sometimes after aerobic composting.
