Sound waste management and optimisation of resource recovery require reliable data on solid waste generation and composition. In the absence of standardised and commonly accepted waste characterisation methodologies, various approaches have been reported in literature. This limits both comparability and applicability of the results. In this study, a waste sampling and sorting methodology for ef...

Zirconium tungstate as an inorganic ion exchange material has been synthesized at different conditions. The materials were characterized by means infrared spectroscopy, thermo gravimetric analysis, and X-ray diffraction techniques. The stability of the ion exchangers was investigated in acidic and alkaline media. Ion exchange properties of synthesized materials were studied by measuring the dis...

Bhutan lacks the solid waste data which are essential parameters for planning and scheduling of municipal solid waste management (MSWM) systems. The first ever large-scale research survey on solid waste generation and characterization in the urban areas of Bhutan was conducted between November 2007 and January 2008 using the method of waste sampling at source. The MSW generation rates in the ur...

7 Abstract 8 An existing materials flow model is adapted (using ExcelTM and AMBERTM model platforms) 9 to account for waste and hidden material flows within a domestic environment. Supported by 10 national waste data, the implications of legislative change, domestic resource depletion and 11 waste technology advances are explored. The revised methodology offers additional 12 functionality for e...

Waste management practices can impact greenhouse gas (GHG) emissions by affecting energy consumption, methane generation, carbon sequestration, and non-energy-related manufacturing emissions. This paper examines GHG emissions and sinks, from a life-cycle perspective, for selected paper, glass, metal, and plastic materials comprising about one-third of municipal solid waste (MSW) generated in th...

The total production of plastics is currently more than 230 million tonnes/year, which will increase to 400 million tonnes in 2020, based on a very conservative growth rate of about 5% per year [1, 2]. The increasing consumption of polymer products, in various fields, generates a large quantity of waste materials, which equates to more than 12% of the urban solid waste stream [3]. Therefore, th...

Electronic waste (e-waste) is the fastest growing type of solid waste because of the continual improvement of electrical and electronic equipment. The e-waste recycling business is a large and rapidly consolidating business in all areas of the developed world (US Environmental Protection Agency 2011). The recovery of precious metals, such as copper, gold, silver, and palladium, is the incentive...
