TL;DR: The present review aims to provide environmental managers and decision-makers with a thorough list of practical applications of the multi-criteria decision analysis techniques used to solve real-life waste management problems, as well as the criteria that are mostly employed in such applications according to the nature of the problem under study.

TL;DR: Large discrepancies were found in the selection of the environmental emissions to be included and how they were estimated in the analysis, and consolidation of the modelling approach in the following area are recommended: quantification of fugitive gas emissions and modelling of disposal practices.

TL;DR: The main objective of the present study was to determine indicators to estimate the amount of CDW generated on site both globally and by waste stream, and suggest that the average composition of waste generated onSite is mostly concrete and ceramic materials.

TL;DR: The preliminary estimate of the magnitude of food waste generation in South Africa is in the order of 9.04 million tonnes per annum, and on a per capita basis, overall food waste inSouth Africa in 2007 is estimated at 177 kg/capita/annum and consumption waste at 7 kg/Capita/Annum.

TL;DR: The result of field study showed that it is a supplementary, and necessary, step in finding the best candidate landfill site from land with high suitability in Mahshahr County, Iran.

TL;DR: This study represents the first systematic effort to map and analyse agricultural plastic waste generation and consolidation in Europe and focuses on areas of high concentration of agricultural plastics.

TL;DR: This assessment suggests the potential for filling the data gaps, and preliminary results demonstrate that the reduction of particle size and the increased surface area for the CPW will result in higher reaction rates and monosaccharide yields for the pretreated waste material.

TL;DR: The history of tailing disposal in China is reviewed, three cases of tailings dam failures are discussed and failure mechanisms are explored, and the procedures commonly used in China for planning, design, construction and management of Tailings impoundments are discussed.

TL;DR: An overview of the municipal solid waste (MSW) management in Beijing, a city with a resident population of about 19.61 million in 2010, is presented in the article.

TL;DR: The objective of this research was to generate a selective classification and quantification model of C&D waste based on the material resources consumed in the construction of residential buildings, either new or renovated, namely the Conventional Constructive Model (CCM).

TL;DR: It is concluded that swine manure larvae bioconversion technology with subsequent production of value-added bio-products can be a promising avenue when considering a programme to reduce waste products in an intensive animal production system.

TL;DR: The main objective of this study was to analyse the current status of healthcare waste management in Turkey, and to investigate the most appropriate treatment/disposal option by using different decision-making techniques.

TL;DR: This article assesses the available data and sets priorities for further research aimed at developing solutions to improve the recycling of seven critical metals or metal families (antimony, cobalt, gallium, germanium, indium, REE and tantalum), including the use of antimony as a flame retardant.

TL;DR: The potential of the earthworm Eisenia andrei to modify chemical and microbiological properties, with a special focus on the nutrient content of fresh organic matter, was evaluated during 16 weeks of vermicomposting of cattle manure and sewage sludge.

TL;DR: The present study aimed to explore the current status of medical waste management in western China and found that sufficient training programmes and protective measures should be provided by healthcare facilities to all relevant personnel and adequate financial support and effective administrative monitoring should be performed by local authorities.

TL;DR: Energy analysis showed that metal chlorides and sulfides were prone to volatilize or to be decomposed at elevated temperature compared with sulfates and phosphates owing to low binding energy in absolute value (VLFA), which led to the different volatILization behavior of metal compounds in a high temperature, oxygen-enriched atmosphere.

TL;DR: It was found that attitude toward the importance of recycling had a positive correlation and was the main determinant of recycling behaviour among these householders and a need to investigate the specific behaviour of multicultural householders regarding source-separated collection and the recycling of hazardous, electronic and bulky wastes.

TL;DR: The measurement results suggest that the waste incineration plant of Bozen is not a significant source of polychlorinated dibenzo-p-dioxin, or fine and ultra-fine particles, and that other monitoring systems confirmed these results.

TL;DR: Landfilling is the ultimate disposal technology which is relevant even when other advanced options are being used for recycling and/or volume reduction, and the move from landfill-based to resource recovery-based waste management is becoming increasingly important.

TL;DR: A new technique is presented, using System Dynamics modeling, to predict generated medical solid waste in a developing urban area, based on a set of limited samples from Jenin District hospitals, Palestine, to indicate that a new forecasting approach may cover a variety of possible causative models and track inevitable uncertainties when traditional statistical least-squared regression methods are unable to handle such issues.

TL;DR: A theoretical framework for integration based on a case study in Lahore, Pakistan, is presented and it is suggested that the municipal authority should draw up and agree on a formal work contract with the group of waste pickers already operating in the area.

TL;DR: The findings indicated that the selected Nigerian healthcare facilities were lacking in the adoption of sound MW management (MWM) practices, and suggests an urgent need for review to achieve vital reversals in the current trends.

TL;DR: Recommendations were made to design integrated waste management solutions that are optimal not only from the ecological and social points of view, but which are also realistic within the given economic situation.

TL;DR: The factors that should be considered to achieve net GHG reductions from incineration were analysed from a life cycle perspective and considerations were applied to the energy supply requirements in seven Japanese metropolises taking into account the energy demands of households.

TL;DR: The digestate obtained at the end of the run showed rather good features for being classified as an organic fertilizer according to Italian law, however, a residual phytotoxicity level was detected by a standardized test showing a germination index of about 50%.

TL;DR: The results showed that the current integrated waste management of Lombardia region is already characterised by good energy and environmental performances, but there is still room for further improvement and actions based on a series of technological modifications can be undertaken to improve the overall system.

TL;DR: Energy contribution from anaerobic digestion of food waste to the total energy requirement in Australia remains low, partially due to the high energy consumption of the country, however its appropriateness in low density regions, which are prevalent in Australia, may allow digesters to have a niche application in the country.

TL;DR: The RSM model was appropriate for optimizing CH4 production in the process of anaerobic co-digestion of multiple substrates and had significant effects on CH4 potentials.

TL;DR: The results of the toxicity characteristic leaching procedure indicated that, among the metals, the concentrations of lead (Pb) and copper (Cu) in fly ash leachate exceeded thresholds, while the concentrationsof studied heavy metals in bottom ash leachesate were all below the regulatory limit.

TL;DR: The debate on recycling is revisited, resorting to fundamental arguments, sometimes forgotten in a one-dimensional drive towards material cycles, does a high percentage of municipal solid waste (MSW) fractions collected for potential recycling translate into maximum sustainable resource efficiency?
