Sources and Streams of Electronic Waste

investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

The characteristics of plastics - rich waste streams FROM END - OF - LIFE ELECTRICAL AND ELECTRONIC EQUIPMENT

The results from numerous studies on the plastics fractions obtained from waste electrical and electronic equipment have been analysed and an assessment made of their suitability for recycling or other forms of recovery. In view of the challenge to ensure the suitability for mechanical recycling by removal of various substances, it is concluded that it is prudent to explore the benefits or othe...

Bacteriophage Disinfection of Engineered Waste Streams BACTERIOPHAGE DISINFECTION OF ENGINEERED WASTE STREAMS

The threat of bacterial contaminants in water distribution systems and in the environment is of unremitting concern for environmental engineers. This problem is compounded by the overuse of antibiotics and the resulting increased prevalence of antibiotic resistant pathogens in engineered waste streams and hospital wastewater effluents. Through defects in sewer systems these pathogens are furthe...

Membrane Condenser for Particulate Abatement from Waste-Gaseous Streams

Membrane Condenser (MC) is a novel membrane contactor operation recently investigated for the valorization of industrial waste gaseous streams. In particular, until now, it was applied for water recovery from flue gas, cooling tower plumes, etc. More recently, its effectiveness and flexibility in contaminants (such as, NH3 , HF, SO2 ) removal and control from waste gaseous streams was also prov...
