How Palm Oil Is Extracted
The usual plant oil extraction and separation process (e.g. olive or palm oil, tea seed oil, etc.) involves the extraction of oil-bearing plant parts (seeds, fruits, skins) that are squeezed and milled. The vegetable oils contained therein are collected and purified by centrifugal separation technology. The palm oil production process is divided into three main parts: pressing, refining and ...

Valorising Agri-Waste – Agriculture produces an unsustainable amount of waste, so how does the bioeconomy let us derive value from it?
For every kilogram of “usable” crop produced in agriculture, between 1 and 2.5 kilograms of residue is also produced. Of course, some of this residue must remain in the field or be used elsewhere on the farm in order to maintain a healthy ecosystem, but that which isn’t used thus is an unavoidable waste. Minimising waste is one of the central tenets of sustainability: the waste ...

The History of Bottle and Containers – Amphorae and barrels
Amphorae and barrels From ancient times, amphoras and barrels are the most comonly used containers for transporting water, wine and olive oil. The amphora being porous, has the disadvantage of losing some of its liquids by evaporation. The barrels, meanwhile, give a woody taste to the wine. This taste is certainly appreciated by winemakers, oenologists and sommeliers, on the other hand, they ...

Efficiency concept under stochastic consideration of water value in irrigated agricultural land in Crete, Greece
Water is an increasingly scarce and valuable resource. It is generally accepted that there is a finite supply of water. As economies grow there is an increasing demand for water. The application of water to agricultural lands for irrigation is one of the essential uses of this natural resource in many areas. There is competition among agriculture, industry, and human consumption for the ...

Fabrication and application of boron doped diamond BDD electrode in olive mill wastewater treatment in Jordan
A boron doped diamond (BDD) electrode was employed in an electrochemical reactor to oxidize the phenolic content of Jordanian olive mill wastewater. The BDD anode was fabricated using hot filament chemical vapor deposition on niobium and the morphology of the BDD electrode was characterized using an atomic force microscope. Then, electrolysis batch runs were carried out at laboratory scale to ...

Innovative method for recovery and valorization of hydroxytyrosol from olive mill wastewaters
The nutritional properties of olive oil can be attributed to its oleic acid and phenolic compounds content, acting as natural oxidants to prevent human diseases. In particular, hydroxytyrosol has an anti-inflammatory action similar to omega 3 fatty acids from fish oil. The olive oil production was conducted by two extraction procedures: first, a two-phase extraction giving extra-virgin olive ...

Comparative study of isotherm parameters of lead biosorption by two wastes of olive-oil production
Batch isotherm studies were carried out on a laboratory scale: (i) to investigate the effectiveness to remove lead of two wastes (olive stone (OS) and olive tree pruning (OTP)), untreated and chemically treated; and (ii) to examine the applicability of various adsorption isotherms to fit the experimental data. Results from tests were analyzed using seven equilibrium isotherm correlations ...

Treatment of olive mill wastewater by chemical processes: effect of acid cracking pretreatment
The effect of acid cracking (pH 2.0; T 70 °C) and filtration as a pretreatment step on the chemical treatability of olive mill wastewater (chemical oxygen demand (COD) 150,000 m/L; total organic carbon (TOC) 36,000 mg/L; oil–grease 8,200 mg/L; total phenols 3,800 mg/L) was investigated. FeCl3 coagulation, Ca(OH)2 precipitation, electrocoagulation using stainless steel electrodes ...

Assessment of toxicity of the untreated and Pleurotus ostreatus treated olive mill wastewater by using microbiotests
Toxicity of raw and biotreated olive mill wastewater (OMW) was tested using three organisms, Daphnia pulex , Thamnocephalus platyurus and zebrafish ( Danio rerio ). Untreated samples demonstrated LC 50 values of 1.27%, 0.96% and 0.48% v/v against the aforementioned organisms respectively. After treatment with the white rot fungi Pleurotus ostreatus , 50% and 56% reduction in ...

Case study - Olive mill waste water treatment
The production of olive oil generates two kind of waste waters: RINSING WATERS: the quantity is subject to change. It can be re-circulated, after the settling to remove the solids, or discharged directly. SLUDGE: vegetation water with additional water, whose quantity is subject to change. In case of traditional oil mills, the hot additional water flows to the inlet of the centrifuge. Part of ...

Olive Processing
Problem: The aerated ponds were producing a foul odor & the chloride content of the aquifer was increasing to a level endangering the water quality. Solution: A Hydrocal CAF system is installed to treat the pit water only. This stream, which aligns the olives to be pitted, is highly contaminated with oil, grease, and ruptured olive tissue. The separate treatment of this stream alleviates ...

Fertilizer NPK from human urine and olive oil mill wastewaters
The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

Olive oil Mill Wastewater properties change during infiltration through clay soils
Olive oil Mill Wastewaters (OMW), are stored in clay basins in the region of Sfax (Tunisia). Field permeability measurements showed that the clay is not completely impermeable and its structure can be modified by the infiltration of OMW. Analysis of chemical composition of soil revealed the presence of phenolic compounds resulting from the percolation of OMW. An infiltration filled with clay and ...

Statistical modelling of the impact of some polyphenols on the efficiency of anaerobic digestion and the co-digestion of the wine distillery wastewater with dairy cattle manure and cheese whey
The objective of this study was to determine the effectiveness of anaerobic digestion in the treatment of polyphenols (PP) present in olive mill wastewater (OMW) and wine distillery wastewater (WDW). Anaerobic Toxicity Assay (ATA) was conducted to assess the impact of the most representative phenolic compounds present in OMW and WDW: catechol, tannins and p-Coumaric acid, on biogas production. ...

Potential role of
Bacillus endospores in soil amended by olive mill wastewaterThe main aim of this work was to know how spread is laccase activity in spores of Bacillus species isolated from a soil where Italian law allows olive mill wastewater (OMW) spreading, and to investigate the potential role of such autochthonous soil microorganisms in degradation of OMW phenols, and prevention of groundwater pollution. Laccase activity was detected for the first time in spores of ...
