Reclamation of a mine contaminated soil using biologically reactive organic matrices
Organic residues such as sewage sludge, biowastes and composts are increasingly used in land rehabilitation because they can improve the physical, chemical and biochemical properties of soil, and reduce the need for inorganic fertilization. ...

A laboratory-scale comparison of compost and sand—compost—perlite as methane-oxidizing biofilter media
Municipal solid waste landfills produce methane, a potent greenhouse gas. A treatment approach is to passively vent landfill gas through a methane-oxidizing biofilter medium, a porous substrate that facilitates the growth of methanotrophic bacteria. ...

Indicators to assess the recovery of natural resources contained in demolition waste
Demolition waste materials are one of the major industrial waste deposits in many countries and represent an important quantity of potential resources that are not exploited, because the major part of these wastes go to landfill. Indeed, recycling ...
-
On the prevailing construction waste recycling practices
Waste generated from construction and building demolition work constitutes about 68% of all solid waste generated each year in South East Queensland. Consequently, it has created a serious waste management problem. The State Governments of Victoria ...

Recycling of plastic waste by density separation: Prospects for optimization
A review of existing industrial processing and results of alternative processing investigations for separating solid mixtures and specifically recycling plastic waste by density separation is presented. Media density separation is shown to be ...
-
Incentive regulation and performance measurement of the Portuguese solid waste management services
Measuring the performance of solid waste management services usually uncovers very high potential for gains in efficiency and productivity. This circumstance occurs, naturally, due to the fact that these services are outside the market and because ...

Use of stratified cluster sampling for efficient estimation of solid waste generation at household level
Relatively few studies have been performed to characterize municipal solid waste (MSW) at household level. This is due in part to the difficulties involved with collecting the data and selecting an appropriate statistical sample size. The previous ...

Impact of heavy metals on the oil products biodegradation process
Oil products continue to be used as a principal source of energy. Wide-scale production, transport, global use and disposal of petroleum have made them major contaminants in prevalence and quantity in the environment. In accidental spills, actions ...

Unit pricing of household garbage in Melbourne: improving welfare, reducing garbage, or neither?
Charging for household garbage collection per unit of waste is becoming more popular. Discussions in the practical literature focus on unit pricing as a way to encourage diversion to recycling and reduction in waste, but the economics literature ...

Immobilization of organic pollutants in cement pastes admixed with organophilic materials
The results of 2-chloroaniline (2-CA) immobilization experiments in cement matrices, using an organophilic clay modified with phenolic resins as pre-sorbent, are shown. The 2-CA suspended in water was kept in contact with the organoclay for 24 h, ...

Wind erosion of waste impoundments in arid climates and mitigation of dust pollution
Wind can erode and disperse fine-grained material from an impoundment of mining, industrial or municipal waste that stands above the level of its surroundings. Such dust dispersion can be a serious nuisance as well as a health hazard to inhabitants ...
-
Emission of volatile organic compounds from solid waste disposal sites
The emission of volatile organic compounds (VOCs) from a solid waste disposal site for municipal solid wastes was quantified. The VOCs contained in the landfill gas taken at the site were benzene, toluene, xylenes, ethyl benzenes, and trimethyl ...

The effectiveness of Hong Kong`s Construction Waste Disposal Charging Scheme
The Hong Kong Government introduced the Construction Waste Disposal Charging Scheme in December 2005 to ensure that disposal of construction and demolition (C&D) waste is properly priced to reduce such waste. The charging scheme is not only ...
-
A laboratory study on stabilization criteria of semi-aerobic landfill
The semi-aerobic landfill has been widely used as a sustainable landfill technology. However, the stabilization indicator system and stabilization criteria of semi-aerobic landfill have not been developed yet. In this study, the stabilization ...

Immobilization of copper flotation waste using red mud and clinoptilolite
The flash smelting process has been used in the copper industry for a number of years and has replaced most of the reverberatory applications, known as conventional copper smelting processes. Copper smelters produce large amounts of copper slag or ...

Radon Levels in Dwellings of New Mirpur Azad Kashmir, Sub-Himalayas, Pakistan
Radon concentrations were measured in kucha, semi-kucha and pucka houses located on the sedimentary rocks of Early Pleistocene-Pliocene Soan Formation, Pleistocene Mirpur conglomerate and recent deposits. The radon concentration was measured using ...

Sources and levels of potentially toxic elements in the biodegradable fraction of autoclaved non-segregated household waste and its compost/digestate
Waste that reflected the average UK composition of household waste was treated by autoclaving at the three set pressure/temperature levels of 2.7 bar/130 °C, 6.2 bar/160 °C and 15.5 bar/200 °C. The biodegradable fraction of the autoclaved household ...

Application of magnetic separation technology for the recovery of colemanite from plant tailings
In this study, colemanite was recovered from tailings produced by the Kestelek (Turkey) Processing Plant by magnetic separation. Magnetic susceptibility measurements revealed that colemanite is diamagnetic in character whereas gangue minerals are ...

Site selection of sanitary landfills on the small island of Mauritius using the analytical hierarchy process multi-criteria method
This paper focuses on the application of a multi-criteria analysis methodology — the analytical hierarchy process — for the locating of a sanitary landfill on the small island of Mauritius. Four candidate sites were assessed using three main ...

Slope failures in municipal solid waste dumps and landfills: a review
Between 1977 and 2005 six large-scale failures of municipal solid waste dumps and landfills have been recorded in the technical literature. The volumes of waste mobilized in the failures varied from 10—12 000 m3 in a failure that killed nearly 300 ...
