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

Chemical properties of plant-based biochar to be used as soil fertiliser in Galicia (NW Spain)

Ferreiro-Domínguez N., Salman S., (Corresponding) Mosquera-Losada M.
Topic: 
Recycling of materials to new products
The excessive use of chemical fertilisers can cause soil acidification, depletion of soil quality, and biodiversity loss. Alternatively, biochar can improve crop productivity due to its ability to bind macronutrients and micronutrients and also adsorb various contaminants. However, the properties...Read more

Seasonal fluctuations of PM2.5 concentrations at six Greek islands

(Corresponding) Fameli K., Kotrikla A., Polydoropoulou A., Mihalopoulos N., Grivas G., Stavroulas I.
Topic: 
Air pollution
PM2.5 concentrations in urban areas vary significantly spatially and seasonally. Measurements can be affected by multiply parameters such as anthropogenic activities, meteorological conditions as well as land use. In the present study one-year PM2.5 measurements from the network of low-cost sensors...Read more

A study of the properties of alkali activated cement concrete with potassium carbonate activator.

(Corresponding) Mavroulidou M.
Topic: 
Net Zero emission transition
Alkali-activated cements (AAC) have recently attracted the vivid interest of the civil engineering industry as promising innovative alternatives to Portland Cement (PC) which is responsible for 8% of anthropogenic CO2 emissions. In this context, this paper studies concrete produced using potassium...Read more
