Valorisation of polyolefins into magnetic carbon nanotubes: application as catalysts in wet peroxide oxidation of paracetamol
Sanches L., (Corresponding) dos Santos Silva A., Fontana Roman F., Diaz de Tuesta Triviño J., Alves da Silva F., Gomes H.
Topic:
Advanced oxidation processes
This work deals with the application of magnetic carbon nanotubes (MCNTs) in the catalytic wet peroxide oxidation (CWPO) of paracetamol (PCM), a pharmaceutical compound selected as model contaminant of emerging concern (CEC). MCNTs were synthetized by catalytic chemical vapor deposition (CCVD) at...Read more
Phytoextraction of cadmium contaminated soils by ornamental plant: growth response, tolerance index and accumulation
(Corresponding) Gul I., Manzoor M., Zaheer M., Ahmad I., Shah G., Kallerhoff J., Arshad M.
Topic:
Soil and groundwater contamination and remediation
Cadmium (Cd) contaminated soil is a global concern and restoration of contaminated soil is challenging due to its persistence and non-biodegradability. In this study the phytoextraction capability of ornamental plant (Pelargonium zonale) for remediating Cd contaminated soil was assessed. For this...Read more

Gravity-driven oil/water separation using PVDF-HFP electrospun nanofiber membranes
Mavukkandy M., Ibrahim Y., Almarzooqi F., Naddeo V., Alhseinat E., Karanikolos G., Banat F., (Corresponding) Hasan S.
Topic:
Wastewater treatment
With increasing industrialization and lenient waste disposal practices, oil-contaminated wastewater has become a significant environmental concern. Oil spills associated with oil exploration and transportation will continue to pose an ecological threat as long as we depend on oil for energy needs...Read more

Transferring the Carbonation of Biomass Bottom Ash from Batch to Continuous Operation
(Corresponding) Schnabel K., Brück F., Pohl S., Weigand H.
Topic:
Mineral carbonation of alkaline waste materials
Biomass incineration residues may be used for CO2 capture and storage by carbonation of waste-borne metal hydroxides. Moist carbonation of these ashes can be performed under mild conditions (ambient pressure and temperature) and accelerated by using a CO2-rich gas. The process requires the wetting...Read more

Carbon nanotubes synthesized from LDPE for application in wet peroxide oxidation of paracetamol
(Corresponding) Roman F., Marim Lopes J., Diaz de Tuesta J., Lenzi G., Tavares da Silva A., Faria J., Gomes H.
Topic:
Advanced oxidation processes
Carbon nanotubes (CNTs) were produced by chemical vapor deposition (CVD) considering low-density polyethylene (LDPE) as a carbon source and as an alternative to upcycle plastic solid waste. The CNTs were synthesized over bimetallic catalysts (Ni and Fe) supported on Al2O3 and purified with H2SO4 to...Read more
How does presence of microplastics impact biogas production?
Resnik N., (Corresponding) Žgajnar Gotvajn A., Griessler Bulc T.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The aim of this study was to evaluate the inhibition on the biogas production caused by microplastics (MPs). Wastewater treatment plants (WWTPs) are receptors of MP. After wastewater treating, more than 90% of MP could be retained in the sludge. Anaerobic digestion of the excess sludge can help...Read more
Introducing UWAB 2.0. and exploring next steps for agent based modelling in domestic water demand.
(Corresponding) Koutiva I., Eftaxias K., Makropoulos C.
Topic:
Estimation and prediction under past and future conditions (climate, population, land use change)
Domestic water consumption projections are needed to manage the urban water supply system in different spatiotemporal resolutions depending on the type of the supported decision. For instance, operational decisions require predictions of fine resolution (hourly or lower), while tactical and...Read more
Efficiency of Arsenic Removal from Water Using Fe-Modified Biochar from Date-Palm-Leaves Combined with Spectral Induced Polarization (SIP) Monitoring
Siddiq O., (Corresponding) Tawabini B., Kirmizakis P., Kalderis D., Ntarlagiannis D., Soupios P.
Topic:
Water treatment
In this study, lab-scale column batch adsorption experiments were conducted to demonstrate the efficiency of Iron-modified Biochar (Fe-BC) produced from date-palm leaves at 500oC to remove arsenic (As) from contaminated water. The As removal capacity were monitored by both chemical analysis and...Read more

Effects of nitrogen fertilizer on photosynthetic light energy transfer and use in hybrid fescue under drought stress
(Corresponding) Januškaitienė I., Dikšaitytė A., Sujetovienė G., Žaltauskaitė J., Kacienė G., Miškelytė D., Juknys R.
Topic:
Ecology, environmental change and management
The aim of this study was to investigate the response of chlorophyll a fluorescence parameters of hybrid fescue (× Festulolium loliaceum (Huds.) P. Fourn.) under partly regulated environment and drought stress effect. The results showed that the increasing nitrogen content increased the values of...Read more
Integrating Seaport Infrastructure Monitoring Approaches to Improve Smartness and Climate Adaptive Capacity
(Corresponding) Tsaimou C., Chalastani V., Sartampakos P., Tsoukala V.
Topic:
Climate change mitigation and adaptation
Seaport infrastructure monitoring promotes the development of an effective management system that ensures functionality, structural capacity and safety. Monitoring approaches are considered to be a useful tool in an attempt to deal with growing global trends, such as seaport “smartness”, or with...Read more
