The presence of rare earth elements and critical metals in waste electric and electronic equipment: challenges for recovery
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
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...
The recovery of metals from WEEE: state of the art and future perspectives
CEST2017 - Electric and electronic waste
Metals are essential elements in the modern technology as they are widely used for several industrial applications such as the manufacturing of electronic devices. Besides common metals, such as copper, iron and aluminium, electronic appliances can contain precious metals as well as metals defined...
Biomining – Biotechnological Systems for the Extraction and Recovery of Metals from Secondary Sources
CEST2017 - Electric and electronic waste
Biomining is the common term used to define processes that utilize biological systems to facilitate the extraction of metals from ores. Nowadays, a biomining concept can be defined as a two stage combined biological systems (1st stage bioleaching and 2nd stage biosorption) in order to perform the...
Exploration of the material distribution of complex components in waste electrical and electronic equipment
CEST2017 - Electric and electronic waste
Technological development combined with a rapid and global market penetration has led to high volumes of Waste Electrical and Electronic Equipment (WEEE). Simultaneously, the use-phase has become shorter resulting in an annual growth rate of WEEE between 3-5%, which makes WEEE one of the fastest...
WEEE data management in Germany and Serbia
CEST2017 - Electric and electronic waste
In Jordan and as in many other Mediterranean countries olive oil production is one of the major agricultural production, it is estimated that the annual production of olive oil in Jordan approximately 21.5 thousand tons per year. O the other hand the process of olive oil extraction generates around...
The recovery of rare earth metals from WEEE leaching solution via liquid-liquid extraction
CEST2017 - Electric and electronic waste
The recovery of rare earth metals (REMs) from end-of-life products, such as Waste Electrical and Electronic Equipment (WEEE), is drawing great attention as an attractive strategy for promoting the sustainable development. The hydrometallurgical technique of solvent extraction has been reported to be...
Assessment of the Demand of Critical Materials for Fuel Cell Micro CHP for Households in Germany
CEST2017 - Electric and electronic waste
Due to the pressing necessity of switching to alternative sources of energy, fuel cells (FC) for household applications have emerged as an alternative for decentralized energy supply. Despite the advancement on technological developments, concerns on the availability of critical raw materials...
WEEE collection and CRM recovery trials: piloting a holistic approach for Scotland
CEST2017 - Electric and electronic waste
Re-Tek UK and its partners, Enscape Consulting and the University of West of Scotland commenced trials for the collection and recovery of critical raw materials from waste electrical and electronic (WEEE) products in July 2016. Sponsored by the EU LIFE funded project ‘Critical Raw Material Closed...
Applied WEEE pre-treatment methods: Opportunities to maximizing the recovery of critical metals
CEST2017 - Electric and electronic waste
WEEE is a fast-growing waste stream that includes potentially hazardous substances, but also valuable secondary raw materials, which can be recovered by adequate recycling and recovery treatment. In the last years, the research interest has moved from the conventional recycling (recovery of ferrous...
Conceptual design for data flow for a database management system for the sustainable recovery of critical metals from waste electrical and electronic equipment
CEST2017 - Electric and electronic waste
Sustainable recovery of critical metals (CM) from Waste Electrical and Electronic Equipment (WEEE) in the European Union (EU) requires information for detailed analysis, monitoring and decision-making. Related knowledge is currently insufficient or disseminated through the network of stakeholders...
Simulation and economic analysis of a hydrometallurgical approach developed for the treatment of waste printed circuit boards (WPCB)
CEST2017 - Electric and electronic waste
This paper presents the main achievements of a hydrometallurgical process to recover base and precious metals from waste printed circuit boards (WPCB). The technology comprises a first leaching process performed in a two-step counter current way with sulfuric acid and hydrogen peroxide for base...
Estimation of Waste Mobile Phones in the Philippines using Neural Networks
CEST2017 - Electric and electronic waste
Waste mobile phone is one of the subgroups of e-waste which is defined as discarded electronic products in the Philippine context. This study estimated current and projected quantities of waste mobile phones in the country using feed forward neural network. The neural network architecture used had...
