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...

The carbonization of coal to produce metallurgical coke is an alternative route for the feedstock recycling of plastic wastes of different structures and origins. Individual plastics or mixed plastics of domestic origin can be incorporated into typical coking blends as secondary raw materials. The effects of the composition of the plastic wastes on the thermoplastic properties of coal, coking p...

Lactic acid can be produced by fermentation of organic matters present in various wastes with the addition of various carbon and nitrogen sources using Lactobacillus species. Organic wastes form kitchen garbage and foodprocessing industries are especially rich in carbon and moisture content. The present study investigates the treatment of the organic wastes using microbiological process for eff...

I n common with most industrial processing industries, the fermentation industries are concerned with waste disposal situations that often become critical. Fermentation wastes usually occur in liquid or solid forms, although some gaseous wastes are also produced. It is worthy of note that, in addition to the problems involved, the disposal of these wastes is particularly interesting to fermenta...

Inconsistencies are present in the management options for healthcare wastes in Mongolia. One of the first critical steps in the process of developing a reliable waste management plan requires the performance of a waste characterization analysis. The objectives of this study were an assessment of the current situation of healthcare waste management (HCWM) and characterization of healthcare waste...

The production of waste has increased over the years and, lacking a recycle or recovery solution, it is forwarded to landfill. The incorporation of wastes in cement-based materials is a solution to reduce waste deposition. In this regard, some researchers have been studying the incorporation of wastes with different functions: aggregate, binder and addition. The incorporation of wastes should t...

The Toxicity Leaching Characteristic Procedure (TCLP) is used by some to estimate the potential hazard that chemicals in solid wastes represent to public health and the environment. This use is done mechanically without understanding the origin of this procedure and the severe limitations and unreliability of this procedure in estimating public health and environmental hazards of the potentiall...
