In this study, alkali silica reaction (ASR) expansion and strength characteristics of mortar containing waste glasses are analyzed in terms of waste glass content and glass color. Three different colors of waste glasses (white, green and brown) are replaced with sand at ratios of 10%, 30% and 100% by weight. The mixtures used in this study did not show a considerable ASR expansion. All batches ...

This article aims to design an increasing block pricing model to estimate the waste fee with the consideration of the goals and principles of municipal household solid waste pricing. The increasing block pricing model is based on the main consideration of the per capita disposable income of urban residents, household consumption expenditure, production rate of waste disposal industry, and infla...

We assessed the economic impact to the United States payer of recombinant human growth hormone (rhGH) utilization, comparing the relative dosage efficiency of marketed pen-based and vial-based products in a pediatric and in an adult population. A budgetary impact model calculated drug costs based on product waste and cost. Waste was the difference between prescribed dose, based on patient weigh...

The excessive wastage of materials, improper management on site and low awareness of the need for waste reduction are common in the local construction sites in India. Today, in most European countries, it is economically feasible to recycle up to 80–90% of the total amount of construction waste and most demolition and recycling technologies are generally easy to implement and control (Lauritzen...

This study proposed a novel way for global greenhouse gas reduction through reusing China's waste oil to produce biofuels. Life cycle greenhouse gas mitigation potential of aviation bio-kerosene and biodiesel derived from China's waste oil in 2010 was equivalent to approximately 28.8% and 14.7% of mitigation achievements on fossil-based CO2 emissions by Annex B countries of the Kyoto Protocol i...

This paper describes a strategic level simulation model developed to help stakeholders understand the Los Angeles solid waste system. The model structure is based on a “recycling loop” incorporating five interconnected sectors: consumption, collection, processing, disposal, and production. The user interface includes eight strategic decision levers (product durability, waste in products and pac...

This research deals with the study and modification of the initial process used by the General Electric Silicones plant to produce a useful material from the hazardous waste it generates. The generation and treatment of the waste is given in a brief overview. Samples taken at various stages in the industrial process were characterized by chemical and physical analyses. Results showed that amorp...

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...
