Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of wa...

With the introduction of producer responsibility legislation within the UK (i.e., waste electrical and electronic equipment directive and end-of-life vehicles directive), specific recycling and recovery targets have been imposed to improve the sustainability of end-of-life products. With the introduction of these targets, and the increased investment in post-fragmentation facilities, automated ...

Toluidine Blue O (TBO) is a cationic dye which is extensively used in the industries. In the present paper a simple and efficient wet chemical method was introduced for removal of TBO from waste aqueous solution. Magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...

background: recently, the rapid increase in quantity and type of waste has resulted to environmental pollution and health hazards which serve as a major challenge to humans. the level of this waste can be so high that dangerous chemicals and biological contaminants can be found in ordinary household waste. major sources of waste in every city are mostly from care/health centers. hence, this stu...

Material separation technology is critical to the success of the material recycling industry. End-of-life products, post-consumer waste, industrial excess, or otherwise collected materials for reuse are typically mixed with other incompatible materials. These materials must be segregated using material separation processes. This thesis investigates the performance and design of material separat...

Some present and possibly future waste disposal methods involving substantial immediate volume reduction of waste processed. 'This paper discusses data on solid waste disposal methods used in the plastics industry as obtained in a recent questionnaire survey of the polymer produc­ tion and plastics fabrication sections of this industry. Regional facilities for collective'inCineration are descri...

Membrane assisted liquid extraction(MALE) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. The present contribution outlines the classification of membrane assisted ...

Urine is the waste fraction from households which contains the largest amounts of nutrients. In Sweden it contains approximately 70% of the nitrogen and 50% of the phosphorous and potassium in all household waste and wastewater fractions. During the 1990-ies, urine separation has been thoroughly investigated in waterborne systems in Sweden. Measurements have shown that between 50% and 85% of th...
