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...

The analysis of solid waste or incinerated residue for information regarding the chemical constituents involved the development and adoption of analytical methods. Methods were developed for the determination of nitro­ gen, carbon, hydrogen, protein, chemically decomposable organic and calorific values. The chemical composition of two types of residue and unburned solid waste was de­ termined u...

This paper presents an overview of current solid waste management practices in Kohima, Nagaland, India and suggests solutions to some of the major problems. The levels of socio-economic development determine the quantity and composition of solid waste. Higher the level of economic development, greater the proportion of waste composition. The total population of the city is 1,32,836, among those...

How Much Waste is Wasteful? Although medical and infectious wastes are often highlighted in evaluations of Hospital Solid Waste Composition a hospital’s waste stream, these hazardous wastes constitute only 15% of a hospital’s total waste generation. The remaining 85% of a hospital’s waste, which is Other 10% Wood 3% Glass 7% Plastics 15% Food 10% Metals 10% Paper 45% considered to be nonhazardo...

Ma’an city faces serious administrative challenges in managing their municipal solid waste (MSW) due to the lack of adequate information of the composition and quantities of generated solid waste. The overall objective of this research is to gain more reliable information about quantities and composition of MSW stream in Ma’an city. In this work, field survey along with a separation study at wa...

the construction industry is a major consumer of new materials. given that material production for construction work accounts for a significant percentage of all energy consumed nationally in newly developing countries, it becomes vital that the construction industry strives to reduce waste at all stages of construction. however, the importance of these construction wastes in terms of types and...

Vine-shoots are an important waste in all viticulture areas that should be re-used with innovative applications. The aim of this work was to produce Airén waste vine-shoot aqueous extracts by four solid-liquid extraction techniques such as conventional solid-liquid extraction (CSLE), solid-liquid dynamic extraction (SLDE-Naviglio), microwave extraction (ME), and pressurized solvent extraction (...

The study examined the problem of waste disposal and management in Ughelli. A field survey was undertaken to determine the types, volume, effects and methods of managing solid waste in the Ughelli. The volume of waste was measured at dumpsites in the four existing quarters and from household bins. Appropriate waste characterization methods were employed in classifying the waste into various com...

the aim of the present paper was to assess the maximum biochemical methane potential (bmp) of municipal solid waste. a fresh stock of the biodegradable fraction of municipal solid waste was composed based on the typical composition of biodegradable waste disposed at the landfill. bmp tests were performed under controlled conditions. the cumulative methane generation profile was corrected for me...

An interface to ADM1 was developed to estimate the solid waste composition from its practical characteristics. The interface was based on COD, elemental, charge and covalent bond balances to conceal any error in collected characteristics from different sources. The interface was validated by reported characteristics of manure and food wastes and determined with relevant accuracy the wastes’ com...
