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...
Thermally treated aluminium waste-filings, a low cost and efficient adsorbent for phosphorus removal from water
Water and Wastewater Treatment
A facile strategy toward modification of aluminium filings (AF), a waste material from aluminium manufacturing industry, into a highly efficient adsorbent was examined. AF was simply treated with thermal modification to form a cheap adsorbent for Phosphorus (P) removal from aqueous solutions. The...
Universal Thermal Climate Index (UTCI) and synoptic circulation patterns over the metropolitan city of Athens, Greece
Global Environmental Change
The present study aims to investigate the human thermal stress with respect to the synoptic scale circulation over the metropolitan city of Athens in Greece. The Universal Thermal Climate Index (UTCI) was applied in order to assess the levels of thermal stress employing three-hour meteorological...
The Right of Thirst: Water as a Human Right and as a Commons
General
Water is not only a vital natural resource but is also a social symbol that makes it a ‘total social fact’. ‘Hydroschizophrenia’ is a term that characterizes the present condition of the status of water and reflects a disconnection between water and society. Liberal environmentalism considers the...
Scavenging of atmospheric particulates by snow in Changji, China
Air Quality
Changji is an arid city in the north west of China which suffers from severe air pollution due to increasing vehicle use and heating with coal. Samples (TSP, PM10, PM5, PM2.5) were collected before and after several snow events, for revealing the snow scavenging effect and influencing mechanisms...
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...
Assessment of the biodegradation capacity of Azolla on polycyclic aromatic hydrocarbons in crude oil
Environmental Sciences
In this study, the potential use of Azolla filiculoides Lam. for the bioremediative solution to polycyclic aromatic hydrocarbon (PAH) pollution due to crude oil spills in freshwater was investigated. The plants were grown in nitrogen-free Hoagland nutrient solution media containing 0.05%, 0.1%, 0.2%...
Uncertainty analysis in sizing rainwater harvesting tanks in an isolated island with limited water resources
Hydrology and water resources
This research work focuses on the analysis of the involved uncertainty and the corresponding reliability in the sizing of rainwater harvesting systems. For this reason, an uncertainty analysis was carried out, based on 23 years of historic daily record of a station in Kimolos Island (Aegean, Greece)...
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...
