Current state and challenges in WEEE recycling industry in Serbia - case study

(Corresponding) Berežni I., Batinić B., Stanisavljević N., Marinković T.
Topic: 
Electric and electronic waste
Waste from electrical and electronic equipment (WEEE) is defined as a special waste flow due to the fact that it contains hazardous materials and should not be mixed and treat with other waste streams. In order to ensure adequate environmental protection and proper management of this waste flow,...Read more

Recovery of rare earth elements from luminophores using the red alga Galdieria

Čížková M., Bišová K., Zachleder V., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic: 
Electric and electronic waste
The red alga Galdieria phlegrea was used as an experimental organism to test bioaccumulation of rare earth elements (REEs) from luminophores. Algal cells were cultured mixotrophically in a liquid medium with addition of glycerol as a source of carbon. Luminophores from two different sources (...Read more

Improving the quality and quantity of source-separated household food waste in areas of different socio-economic characteristics: A case study from Lübeck, Germany

(Corresponding) Koerner I., Walk S., Deegener S., Wardle D.
Topic: 
Food waste
A method aiming at improving source-separation performance of household food waste (FW) was investigated in two areas with different socio-economic characteristics in Lübeck, Germany. This included the test of a new FW collection system including the distribution of small collection buckets to each...Read more

Biosolids as soil-amendment: evaluation of nutrient leaching in loamy-silty soil

(Corresponding) Venegas M., Fernandez G., Vidal G.
Topic: 
Biowaste
Municipal sewage sludge is a by-product of wastewater treatment. The amount of sewage sludge has increased with the construction and expansion of wastewater treatment plants, while stricter policies have limited its disposal. Anaerobic digestion is a worldwide technology used in sewage sludge...Read more

A novel types of compound for surface treatment of carbon nanotubes for more effective application in polymers

(Corresponding) Hangyási K., Varga C., Nagy R., Simon-Stőger L.
Topic: 
Green chemistry
Nowadays, beneficial management of plastic and rubber waste from different sources and environmentally friendly ways of recycling is becoming an increasing challenge. A possible solution for that issue could be to produce plastic composites usually consisting of heterogeneous phases. That fact and...Read more

Analysis of the content of germanium, tellurium and thallium in the grounded waste of electronic equipment

(Corresponding) Fornalczyk A., Willner J., Jablonska-Czapla M., Rachwal M.
Topic: 
Hazardous waste management
The article draws attention to the problem of the presence in waste electrical, electronic equipment (WEEE) of selected metals from the group of critical metals (germanium), strategic metals (tellurium) and highly toxic elements (thallium). Due to low content of these metals in e-waste, they are...Read more

A study of alkali-activated concrete mixes in seawater environments

Mengasini L., (Corresponding) Mavroulidou M., Gunn M.
Topic: 
Marine environment and coastal management
This paper assesses the performance in seawater environment of concrete mixes based on alkali-activated (AA) cements; these are proposed as an alternative to Ordinary Portland Cement (OPC) to address environmental footprint of cement production and to find new uses for waste materials. The proposed...Read more

Coal fly ash zeolites as adsorbents for effective removal of heavy metals and dyes from contaminated waters

Zgureva D., (Corresponding) Boycheva S., Behunová D., Václavíková M.
Topic: 
Wastewater treatment
Recently, the purification of enormous amounts contaminated industrial, agricultural and municipal waters increases the demands of low-cost and technologically feasible techniques. The application of natural zeolites in wastewater treatment is known from many years. A feasible approach for...Read more

Magnetite nanoparticles activated coal fly ash zeolites with application in waste water remediation

(Corresponding) Boycheva S., Miteva S., Trendafilova I., Zgureva D., Václavíková M., Popova M.
Topic: 
Wastewater treatment
The application of zeolites in wastewater treatment is studied long ago but still many unexploited opportunities exist. Recent investigations on natural and synthetic zeolites in water decontamination are focused on the improvement of their adsorption and ion-exchange properties modifying them by...Read more
