Potential of Using real-time OiW monitoring for control of produced water treatment in offshore oil & gas production
(Corresponding) Zhenyu Y.
Topic:
Water treatment
The produced water has been the largest produced fluid stream at most of the current offshore oil & gas production in North-sea. It is not uncommon that the water cut can reach 90% in many matured production fields. No matter the produced water will be eventually discharged to the ocean, or...Read more

Production of activated carbon from oil palm shells via physical activation with H2O and its characterization for use in aqueous phase
(Corresponding) Rincon S., Alvarez D.
Topic:
Energy technologies and sustainability
Oil palm shells (OPS) are a solid residue of the extraction of palm oil having excellent characteristics for production of activated carbon. OPS worldwide production amounts to 17.214 ton (2018) from which Colombia participates with 364 ton. Oil palm shells were first carbonized in a horizontal...Read more
Extraction of Oil from Spent Grounds Coffee using Ultrasound as Pre-Extraction Method
(Corresponding) Cubas A., Hermmann K., Bianchet R., Moecke E.
Topic:
Food waste
The treatment and processing of coffee annually produces a large volume of biological waste, which contributes to environmental pollution, it is estimated that coffee production generates approx. 6 million tonnes of spent coffee grounds per year in the world (GETACHEW and CHUN, 2017). Thus, the...Read more

Environmental genotoxicity and risk assessment in herring (Clupea harengus), Atlantic cod (Gadus morhua) and flounder (Platichthys flesus) caught in the Gotland Basins from the Baltic Sea (2010-2017)
(Corresponding) Pažusienė J., Valskienė R., Stankevičiūtė M., Butrimavičienė L., Baršienė J.
Topic:
Biomonitoring
The Gotland Basins are mostly polluted by anthracene, benz(a)anthracene, benzo(k)fluoranthene, cesium-137, DDE, dioxins, mercury and TBT. These chemicals have toxic, carcinogenic and immunotoxic effect to marine animals. After the World War II chemical weapons (CW) were transported from Germany and...Read more

Lipid production by Rhodosporidium toruloides growing on media presenting composition similarities with the spent sulfite liquor in batch and fed-batch cultures
Michou S., Vastarouchaa E., Sarris D., Kalantzi O., (Corresponding) Papanikolaou S.
Topic:
Environmental biotechnology and bioenergy
Aim of this study is to explore the effect of sodium lignosulfonate (SL), a paper industry by-product, on cell growth and lipid production by the yeast Rhodosporidium toruloides, cultivated on xylose-based media, that mimic the principal waste-stream originated from paper production facilities (viz...Read more

Evaluation of a new millifluidic device for the consistent determination of oil droplet biodegradation kinetics
(Corresponding) Kapellos G., Nagarajan M., Kalogerakis N., Doyle P.
Topic:
Process understanding through innovative sensors and remote sensing
Natural seeps and accidental releases of crude oil in the sea result in swarms of droplets that are carried away by underwater sea currents. The droplets may be created either at the sea surface during the breakup of an oil slick by sea waves, or at the seafloor during the extrusion of crude oil...Read more
Anaerobic digestion of long-chain fatty acids (oleic, palmitic, stearic) with whey protein as the emulsifier
(Corresponding) Eftaxias A., Michailidis C., Diamantis V., Aivasidis A.
Topic:
Environmental biotechnology and bioenergy
Long chain fatty acids are suitable for biogas production, however, they are often responsible for process inhibition, due to their high toxicity even at low concentrations. In this study, anaerobic co-digestion of whey protein emulsified with oleic, palmitic or stearic acid were examined in...Read more

The Agia Zoni II oil spill: Short-term fate and imprint on the marine ecosystem of the Saronikos Gulf, Greece
(Corresponding) Parinos C., Hatzianestis I., Chourdaki S., Plakidi E., Gogou A.
Topic:
Environmental impact of maritime transport
Herein we examine the spatial and temporal imprint of the September 2017 Agia Zoni II tanker heavy fuel oil spill on the marine ecosystem of the Saronikos Gulf, Greece. Based on the chemical fingerprinting approach, by means of gas chromatography - flame ionization detector and gas chromatography–...Read more

Anaerobic co-digestion of poultry manure and used cooking oil for enhanced biogas production
(Corresponding) Eftaxias A., Gkalimanis P., Koskinari M., Koumara A., Diamantis V., (Corresponding) Aivasidis A.
Topic:
Biowaste
Aim of this study was to evaluate the anaerobic co-digestion of diluted poultry manure (DPM) and used cooking oil (UCO). Mixtures of DPM with different UCO dosages (1 to 6% v/v) were prepared using a high-shear emulsifier and digested in batch anaerobic reactors. Increasing the UCO dosage resulted...Read more
