Coal ash zeolite as a self-catalytic-chemisorption system for conversion of carbon dioxide to hydrocarbons
(Corresponding) Boycheva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
At present, the developments of sustainable carbon capture technologies are of the main scientific and technological priority required to mitigate the over generation of greenhouse gases. Three CO2 clean energy production approaches have been outlined: pre-combustion capture, oxy-fuel combustion...Read more

Durability of cement mortars and concretes exposed to biological attack as one of the sustainability parameter – a correlation analysis
(Corresponding) Ondrejka Harbulakova V., Estokova A., Smolakova M., Luptakova A.
Topic:
Energy technologies and sustainability
Among the pillars of the sustainability, the aspect of prolongation of life of constructions has to be involved. Focus on sustainability of construction leads to study of durability of building materials. Phenomenon called biocorrosion, existing mainly in concrete sewer systems, agricultural...Read more
Estimation of Soil Organic Carbon for Sustainable Agriculture using Deep Learning
(Corresponding) Singh S., Kasana S.
Topic:
Agroforestry, forest and agricultural sustainability
The organic carbon percentage is concomitant indicating the mineralization of nutrients and the ability of the soil to hold nutrients cations, structural stability, and water holding capacity. It is necessary to know the quantity of carbon for healthy soil and avoid the production related problems...Read more

Environmental, economic and socio-economic life cycle assessment of the Spanish electricity system
Cerrato M., (Corresponding) San Miguel G.
Topic:
Life cycle analysis (lca)
This paper investigates the sustainability of the Spanish electricity system under four different scenarios for 2030 and 2050 published by a reputable think tank assessing the Spanish Government. The analysis was performed using a life cycle approach and evaluates five sustainability indicators:...Read more
Heterotrophic growth of Chlorella vulgaris on crude glycerol
Gougoulias N., Metsoviti M., Grigoriou M., Lamprakopoulos S., Besios A., (Corresponding) Papapolymerou G.
Topic:
Environmental biotechnology and bioenergy
The heterotrophic growth of C. vulgaris using crude glycerol as the sole carbon source was studied in five 5L flasks. Air in each flask was provided at a rate of 300 L/hr and the contents were continuously stirred with a magnetic bar. Temperature, pH and initial inorganic nutrients (nitrogen,...Read more

(Corresponding) Mondal S., Majumder S.
Topic:
Water treatment
Preparation of an efficient activated carbon for the removal of metal pollutants is a challenging research today. The characteristic features of an efficient phosphate functionalized activated carbon, synthesized by following chemical activation process followed by subsequent functionalization from...Read more
Adsorptive Removal of Marbofloxacin from Milk using Activated Carbons.
GE X., WU Z., KUNZ W., Barge A., (Corresponding) Giancarlo C.
Topic:
Water and wastewater treatment and reuse
The present study aims to remove the residual marbofloxacin (MBX) from milk with activated carbons (ACs) in batch and flow systems to meet the maximum residue limits (MRLs, 0.075 µg mL-1). Different types (granular and powder) and amounts of ACs were studied. In batch mode, 50 mg of commercial...Read more
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
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
