Sustainable water resources governance developments: cross-sectorial policies and societal practice

(Corresponding) Ernsteins R., Skute A., Konkovs K., Lagzdina E., Ozolins M.
Topic: 
Water policy, management and society
The governance process of surface water resources in Latvia, particularly, in small river catchment areas and lake lands, also being Natura 2000 territories, was the main foci for two studies described. Previous traditional research done in related fields in Latvia has been focusing on water...Read more

Polyhydroxyalkanoates (PHAs) Production from the Liquid Fraction of dried/shredded Food Waste

Filippou K., Bouzani E., Kora E., Ntaikou I., (Corresponding) Papadopoulou K., Lyberatos G.
Topic: 
Bioplastics
An enriched culture of Polyhydroxyalkanoates (PHAs)-forming bacteria was developed using the liquid fraction (condensate) which is generated during drying and shredding of food waste. A mixed enriched culture was used for the production of PHAs, in two Draw-Fill Reactors (DFRs). The culture was...Read more

Season Dynamics of Pollution and Changes in Enzymatic Activity in Agricultural Soil near an Industrial Area

(Corresponding) Sukiasyan A., Kirakosyan A.
Topic: 
Agroforestry, forest and agricultural sustainability
The aim of the study was to assess the ecological condition of soils in three regions in Armenia - Hrazdan, Gavar, and Martuni. It was shown that the soil samples from the three regions had low humus content in winter. However, in spring and summer, a significant increase in humus content was...Read more

Nutrients recovery from liquid anaerobic digestate by combining nanofiltration and struvite precipitation - The case of dairy effluents valorization

Tsaridou C., (Corresponding) Karanasiou A., Sioutopoulos D., Plakas K., Tzioumaklis C., Patsikas N., Gliaos P., Karabelas A.
Topic: 
Sustainable supply of raw materials
Results are reported herein of a study aiming to develop an integrated process for valorizing liquid digestate (LD) from an industrial anaerobic digestion (AD) plant treating dairy-processing effluents. The investigated approach involves LD treatment by nanofiltration (NF) membranes, at pilot-scale...Read more

Tolerance mechanisms and adaptive strategies of Moringa oleifera (L) during growth and vegetative development under water stress in hydroponics

Boumenjel A., Papadopoulos A., (Corresponding) Pantera A.
Topic: 
Agroforestry, forest and agricultural sustainability
In order to highlight the potential tolerance and/or resistance of Moringa oleifera (L), to drought during two weeks of germination in vitro. Osmotic water stress was induced under semi-controlled conditions. The water potential of the culture medium was lowered by the addition of...Read more

Solar parks effect on soil properties: Initial results

Du Hamel A., Papadopoulos A., (Corresponding) Pantera A.
Topic: 
Agroforestry, forest and agricultural sustainability
Solar power generation in Greece has only been increasing since the 1980s to become the main source of renewable energy. Today, around 4.1 million m2 of Greek land is covered by solar parks. This article starts with a literature review on how the photovoltaic panels impact their environment and on...Read more

Monitoring soil water content using IoT Time and Frequency Domain Reflectometry Sensors

(Corresponding) Chrysanthopoulos E., (Corresponding) Floros E., Pouliaris C., Tsirogiannis I., Kofakis P., Kallioras A.
Topic: 
IoT-based environmental monitoring
Soil moisture is considered a crucial climatic parameter. Understanding and predicting variations in surface temperature, precipitation, drought, flood and the effects of future climate change need a thorough knowledge of soil moisture fluctuations. Furthermore, quantification of soil water content...Read more

Pilot scale investigation of an advanced photo-electro-chemical oxidation process for treatment of effluents from pesticides manufacturing plants

(Corresponding) Sarasidis V., Petsi P., Plakas K., Karabelas A.
Topic: 
Advanced oxidation processes
This paper reports on the effectiveness of an innovative hybrid advanced oxidation process-scheme aiming to degrade recalcitrant organic compounds in industrial effluents. Following targeted experimental work, a pilot unit was developed/built combining two advanced oxidation processes, based on in-...Read more

Potential contaminants and risk assessment in the Meriç-Ergene Basin under the EU Water Framework Directive

(Corresponding) EKER S., ÇOKAY E.
Topic: 
Emerging pollutants
The European Union's Water Framework Directive (WFD) 2000/60/EC provides a strategic solution to deal with chemical pollution in rivers. The directive encompasses monitoring and detection of 45 priority pollutants and specific contaminants found in surface waters. An increase in the number of...Read more

Treatment of Leachate Wastewater with Fenton Process

(Corresponding) Çokay E., Eker S.
Topic: 
Wastewater treatment
Leachate wastewater produced from landfill areas contains high organic contents and heavy metals. Because of high concentration of organic materials and heavy metals, it can cause toxic effects on the environment. In addition, there is a possibility that leachate can reach to surface and ground...Read more
