Recovery of critical and precious metals from E-Waste
Ippolito N., Birloaga I., Ferella F., Innocenzi V., De Michelis I., (Corresponding) Vegliò F.
Topic:
Electric and electronic waste
Waste of Electrical and Electronic Equipment (WEEE) is the fastest growing waste stream in Europe. This waste contains a high amount of critical and valuable metals as the rare earths defined critical materials from European Commission (2010) and the precious metals. Exhaust fluorescent lamps are...Read more
Influence of Varying Concentration of Toluene in a Soil Biofilter with Water Content Control
Badilla D.
Topic:
Air pollution
Contaminant concentration affects rate of removal of air contaminant in biofiltration. In this study, extent of degradation rate at varying concentrations of toluene (from 50 to 700 ppm) as the air contaminant in terms of elimination capacity (EC) was measured in a soil biofilter with water content...Read more

On the positive influence of Pd species on low-density polyethylene cracking
Pyra K., Tarach K., Majda D., Janiszewska E., Melián-Cabrera I., (Corresponding) Góra-Marek K.
Topic:
Solid waste management
Microporous 12-ring zeolite Beta was impregnated with palladium and evaluated in the cracking of low-density polyethylene (LDPE) cracking. In addition to the catalytic measurements the materials were characterized by X-ray diffraction, chemical analysis and nitrogen adsorption, electron microscopy...Read more

Bottom-up synthesized hierarchical Beta zeolites as the catalysts for low-density polyethylene cracking
(Corresponding) Pyra K., Janiszewska E., Tarach K., Majda D., Góra-Marek K.
Topic:
Solid waste management
Improving mass transport in zeolites Beta by bottom-up hierarchization was aimed at preserving their native microporous acidic characteristic and finally demonstrating their applicability in LDPE catalytic pyrolysis, in contrast to top-down modified analogues.
Keywords:
hierarchical zeolites Beta, LDPE cracking, IR spectroscopy
Market and Trade Network Analysis of EU Emission Trading System
Fotakis D., (Corresponding) Dimos S., Evangelatou E., Mantis A., Mathioudaki A.
Topic:
Environmental management and policies
The European Union Emission Trading System (EU ETS) is the world’s largest cap-and-trade system. The observed price instabilities and the oversupply of the allowances are two characteristics that affect the objectives and the efficiency of the policy.
In this article we investigate the impact of...Read more
Understanding the EU ETS Market Structure Using Transactions of Core Participants
(Corresponding) Dimos S., Evangelatou E., Fotakis D., Mantis A., Mathioudaki A.
Topic:
Environmental data analysis and modelling
European Union Emission Trading System (EU ETS) is a key instrument of EU’s climate policy and the largest international cap-and-trade system. Every allowance transaction is recorded in an electronic registry, called European Union Transaction Log (EUTL). Utilizing the vast amount of EUTL data, we...Read more
Microbial Biodiversity of Municipal Solid Waste (MSW) dumpsites of Cochin, Kerala, India.
Varier J., Kuttamassery N., (Corresponding) Chenichery S.
Topic:
Solid waste management
Cochin, the commercial and industrial centre of Kerala, lies on the south-west coast of Arabian sea. It covers an area of 94.88 Km2. There are two major dumpsites in the city, one at Brahmapuram and other at Kalamassery. The proper management of the waste has been a challenging task for the...Read more

Investigation of Shoreline Morphometry of Kızılırmak Delta’s Lagoons Using Fractal Dimension and Shoreline Development Index
(Corresponding) UYAR A., OZTURK D.
Topic:
Hydrology and water resources
In this study, shoreline morphometry of the Karabogaz, Balik, Uzun, Cernek, Liman, Gici and Tatli lagoons which are located in the Kızılırmak Delta, was investigated by using fractal dimension and shoreline development index. The shorelines of the lagoons were obtained from Landsat 8 OLI satellite...Read more

Application of Ni loaded FAU zeolites in catalytic conversion of 1,2-dichloroethane towards value added products
(Corresponding) Góra-Marek K., (Corresponding) Srębowata A., Kowalewski E., (Corresponding) Tarach K., Pyra K.
Topic:
Nanomaterials in the environmnents applications and effects
The catalytic performance of nickel loaded zeolite materials was found to be dependent on their acidic feature that influenced metal speciation and its dispersion. The selectivity to ethane and ethane of the Ni loaded catalysts increased when reducing both the number of acid sites and average...Read more
Keywords:

(Corresponding) Tarach K., Valencia S., Góra-Marek K., Rey F.
Topic:
Green chemistry
The effect of base leaching on pure silica ITQ-29 zeolite being the counterpart of LTA zeolite, was investigated. The extent of the desilication process over pure silica zeolite was controlled by partial detemplation followed by silicon extraction. The potential of hierarchically porous ITQ-29...Read more
