The presence of rare earth elements and critical metals in waste electric and electronic equipment: challenges for recovery


Sikander A. et al. View all

CEST2017 - Electric and electronic waste

The fastest growing waste stream of waste electric and electronic equipment (WEEE) is not only a threat to our environment, but is also creating a supply risk of certain rare earth metals (REMs) and critical metals (CMs). Despite the fact that Directive 2012/19/EU encourages the prevention of WEEE...

WEEE management in a circular economy perspective: an overview


Alessandra Cesaro et al. View all

CEST2017 - Electric and electronic waste

The circular economy approach represents a strategy to optimize product lifecycles, thus improving the sustainability of consumption patterns. In the European Union a recent legislative proposal has addressed this concept by promoting waste prevention and re-use as well as extensive recovery of...

Impact of bioaugmentation of soil with n-hexadecane-degrading bacteria and phosphorus source on the rate of biodegradation in a soil-slurry system


Mansooreh Dehghani et al. View all

Solid Waste Management

In recent years, n-hexadecane, a component of diesel petroleum hydrocarbons, is frequently detected as the contaminant in many soils and water resources. The main aims of this study were focused on the feasibility of using the biodegradation for the removal of n-hexadecane from the soil-slurry...

Abatement of odour emissions by UV/Ozone oxidation process


Giuseppina Oliva et al. View all

CEST2017- Environmental odour, monitoring and control

The growing expectations of the population and the increasingly stringent regulations about air pollution have resulted in the need to minimize and conveniently treat the waste gas from different emission sources. The emissions from a large variety of plants, including waste and wastewater treatment...

CO2 Sequestration by Mineral Carbonation: A Review


Shashikant Yadav et al. View all

Global Environmental Change

The mineral sequestration, one of the methods of CO2 sequestration, is considered advantageous, as it not only facilitates permanent and leakage free storage of CO2 but also obviates the need for regular monitoring. Mineral sequestration involves the dissolution of minerals and subsequently...
