On the Fenton oxidation of polystyrene microplastics
(Corresponding) Munoz M., Ortiz D., Nieto-Sandoval J., Romera-Castillo C., de Pedro Z., Casas J.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
This work aims at evaluating the fate of polystyrene (PS) microplastics along Fenton oxidation. Experiments were carried out under relatively severe operating conditions (80 ºC) given the high persistence of these solids to oxidation. Slight mass losses (up to 10%) were found after the Fenton...Read more

Continuous flow hydrodechlorination for micropollutants removal using an innovative Pd-based Catalytic Membrane Reactor
(Corresponding) Nieto-Sandoval J., Gomez-Herrero E., Munoz M., de Pedro Z., Casas J.
Topic:
Water treatment
The aim of this work is to develop a Pd-based Catalytic Membrane Reactor (Pd/CMR) for its application in organochlorinated micropollutants removal by hydrodechlorination (HDC). The external surface of a Al2O3 membrane was homogeneously decorated by Pd nanoparticles (0.2% wt.). The Pd/CMR developed...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
Application of catalytic hydrodehalogenation for the removal of brominated flame retardants
Nieto-Sandoval J., (Corresponding) Benito del Olmo R., Munoz M., De Pedro Z., Casas J.
Topic:
Water treatment
The aim of this work is to evaluate the feasibility of aqueous-phase catalytic hydrodehalogenation (HDH) for the fast and environmentally-friendly degradation of the flame retardant tetrabromobisphenol A (TBBPA). TBBPA is a pollutant of emerging concern characterized by a strong persistence that...Read more
Magnetite-decorated catalytic membrane reactor for the continuous-flow CWPO of micropollutants
(Corresponding) López-Aragó N., Nieto-Sandoval J., Munoz M., de Pedro Z., Casas J.
Topic:
Advanced oxidation processes
This work aims at developing a contactor type Catalytic Membrane Reactor (CMR) for its application in the continuous removal of micropollutants by Catalytic Wet Peroxide Oxidation (CWPO). For such goal, a porous alumina membrane tube was homogeneously decorated with magnetite nanoparticles...Read more

CO2 Utilization for Preparation of Carbon Nanostructures
(Corresponding) Giannakopoulou T., Plakantonaki N., Vagenas M., Papailias I., Boukos N., Todorova N., Trapalis C.
Topic:
Gas emissions control and utilization
The CO2 conversion to valuable materials is a challenging way to manage pollution problems. In the present work, CO2 was used as a feedstock to synthesize solid carbon nanostructures by employing a simple magnesiothermic reduction reaction under constant gas flow in a tube furnace. It was shown...Read more

Nanoplastics mineralization by the intensified photo-Fenton process
(Corresponding) Ortiz D., Munoz M., Carbajo J., M. de Pedro Z., Casas J.
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

Assessing the risks of climate change for cultural heritage – The CLIMASCAPE project
(Corresponding) Cartalis C., Polydoros A., Mavrakou T., Philippopoulos K., Asprogerakas E., Pantazis P., Samarina A., Zoumpaki S., Karambinis M.
Topic:
Environmental management and policies
The protection of cultural heritage sites from the climate change effects is a central priority for protecting the cultural capital of Greece, and the sustainability of the related touristic flows. This paper describes the conceptual framework of the CLIMASCAPE project which aims to develop a...Read more

Optimized use of biogenic waste streams through the combined production of bio-based products and bio-hydrogen
(Corresponding) Küppers M., Brunstermann R., Widmann R.
Topic:
Biowaste
Since 2015, there has been a legal obligation in Germany for the districts and cities to collect biowastes separately, which are then treated in a composting plant or fermentation plant. However, in both aerobic and anaerobic biowaste treatment, a large part of the carbon contained in the waste is...Read more
