In response to a growing societal mandate, land disposal of hazardous wastes is gradually being replaced by treatment technologies. This shift to “alternative technologies” is the result of the impacts of past land disposd practices on other environmental media (groundwater, surface water, and air). A prime motivation for pdopting alternatives to land disposal is to eliminate these cross-media ...

Machine-learning algorithms have recently been applied to electrical power problems due to their potential to reduce waste and improve electrical grid reliability, but deployment of existing research is hampered by unrealistic assumptions. My thesis focuses on overcoming these assumptions. Autonomous agents have enormous potential to reduce electrical waste and improve reliability of the power ...

Customers everywhere demand better products or services quicker with improved cost control and responsiveness. Concurrently, they demand continuity of supply and more involvement with suppliers and others to provide unexpected results. The key concept making this all possible is to significantly reduce waste and its costs. This presentation shows how managing the seven types of waste holds grea...

The present study was undertaken to determine the bacterial agents present in various clinical solid wastes, general waste and clinical sharp waste. The waste was collected from different wards/units in a healthcare facility in Penang Island, Malaysia. The presence of bacterial agents in clinical and general waste was determined using the conventional bacteria identification methods. Several p...

One of the most efficient water conservation mechanisms in mammals is the ability of the kidneys to produce concentrated urine for the elimination of waste products while losing a minimum of water. Depending on the food supply of differing animals, components of the glomerular ultrafiltrate are concentrated in the final urine to different extents. For example, carnivorous animals preferentially...

To eliminate hazardous hexavalent chromium from a brass wire-mill waste, hydrogen peroxide was examined In place of chromic acid for pickling, first in bench-scale tests and then in plant tests. Nthough the elimination of chromic acid requires more rigid control of the ~ wastewater treatment operation and increases the zinc content of the waste-treatment effluent, the economic benefit of substi...

Waste material from the fishing industry disposed off-shore exceeds 250 billion tons/year, and it is considered hazardous due to its high perishability and polluting effect, both on land and sea. Considering the actual production of chitin, chitosan and oligosaccharides from crustaceons, it is understandable how difficult it is to eliminate all the waste material obtained from food industry, th...

Studies over the last two decades have shown that mammalian nonmacrophagic liver endothelial cells clear the blood from numerous physiological and foreign waste macromolecules, such as polysaccharides and proteins released during extracellular matrix turnover, intracellular macromolecules, modified serum proteins, and bacterial and fungal proteins [Smedsrød, B., Pertoft, H., Gustafson, S. & Lau...

Many healthcare organizations are building or renovating patient care facilities. Using Lean Six Sigma methods, nurse leaders can eliminate unnecessary waste and improve work and patient care environments. Starting with a key department like the post-anesthesia care unit is a good way to expose staff and leaders to the potential of Lean.

This paper examines the links between solid urban waste management and peri-urban agriculture in Bamako and Ouagadougou. Staple crop farmers in the vicinity of both cities value urban waste as a source of organic matter and are prepared to pay for it. Cultivation on degraded soils has even been revived in some cases thanks to this readily available resource. However, uncertain land tenure means...
