Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The widespread presence of microplastics (MPs) and nanoplastics (NPs) in aquatic systems has become one of the most challenging environmental issues nowadays. Although advanced oxidation processes (AOPs) have been widely studied for the treatment of persistent contaminants in water, their...Read more

PFAS removal performance of novel technologies for treatment of firefighting water and groundwater
(Corresponding) Hjort M., Dalmijn J., Roest K., ter Laak T., Vaiopoulou E.
Topic:
Soil and groundwater contamination and remediation
Per- and polyfluoroalkyl substances (PFAS) are a group of widely used man-made organic chemical substances. PFAS have been used because of their particular physicochemical properties: most are stable at high temperatures, recalcitrant to chemical oxidation and biological degradation, and act as a...Read more
Properties of dry hydraulic road binder mixture with additional component of cement bypass dust
(Corresponding) Stevulova N., Junak J., Strigac J., Terpakova E.
Topic:
Solid waste management
This paper is aimed at properties characterization of a designed binder mixture containing cement, fine natural limestone, cement bypass dust (BPD), and ground granulated blast furnace slag (GGBS) with an emphasis on a potential utilization of BPD into a normal hardening hydraulic road binder in...Read more
Energy recovery from urea in decentralised wastewater streams
Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.
Topic:
Water, energy and/or food nexus
This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen.
Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more

Wastewater valorisation, energy recovery, urea, adsorption, circular economy.
Investigating the impact of landfill leachates in groundwater quality through the monitoring of multiclass emerging contaminants by LC-HRMS
(Corresponding) Nika M., Gkotsis G., Vasilatos K., Gkogkou A., Stasinakis A., Thomaidis N.
Topic:
Emerging pollutants
Due to their economic advantages, landfills are the primary repository of municipal solid wastes, receiving everyday by-products such as food wastes, plastic containers and product packaging materials, unused pharmaceuticals, textile and other products. As a result of the higher demand and better...Read more

Low temperature conversion of methanol to higher hydrocarbons and hydrogen using a non-thermal plasma
(Corresponding) Dahiru U., Zhang K., Harvey A.
Topic:
Environmental odour, monitoring and control
In recent years, the emission of volatile organic compounds (VOCs) from chemical manufacturing plants, agricultural practises, and indoor sources has attracted public concern, as these emissions have a negative effect on both human health and the environment. VOCs are precursor for the formation of...Read more
Detection of Aflatoxin M1 in milk using Mach-Zehnder optoelectronic immunosensors
(Corresponding) Angelopoulou M., Kourti D., Misiakos K., Economou A., Petrou P., Kakabakos S.
Topic:
Emerging pollutants
Aflatoxin M1 (AFM1) is excreted in milk of animals after ingestion of food contaminated with Aflatoxin B1 (AFB1). AFM1 has been considered as group I carcinogen since 2002, so the consumption of even low concentrations of AFM1 pose a major threat for human health. In this work, a silicon-based...Read more
Alternatives for removing fluoride from water for human consumption and water for reuse
(Corresponding) Nigri E., Santos A., (Corresponding) Rocha S.
Topic:
Water and wastewater reuse
This compilation aims to describe the studies carried out focusing on the treatment of 100-127 mg/L of wastewaters involving different fluoride removal alternatives which demonstrated efficacy. Adsorption by bone char, both in batch as in continuous systems, including chemical and thermal...Read more

Hydrogen and organic acids production from mesophilic and thermophilic dark fermentation of sugarcane vinasse without buffers
(Corresponding) Ribeiro J., Mota T., Oliveira V., Zaiat M.
Topic:
Wastewater treatment
The main objective of this study was to evaluate the valorization of vinasse dark fermentation (DF) through bioH2 and value-added metabolites production without buffers in two similar Upflow Anaerobic Sludge Blanket (UASB) reactors under mesophilic (U30) and thermophilic (U55) conditions. An...Read more

Methane distribution over Greece as derived from Sentinel-5P TROPOMI data
EVANGELOU I., GIALESAKIS N., DASKALAKIS N., (Corresponding) KANAKIDOU M.
Topic:
Climpact: national network for climate change and its impacts
Global warming, induced mainly by greenhouse gases emitted by human activities, is an environmental issue of crucial importance for society. Greenhouse gases, such as methane (CH4), need to be monitored and their anthropogenic emissions quantified in order to be reduced. We here present, the first...Read more
