With the decline in the number of rendering operations due to industry consolidation and concern about Bovine Spongiform Encephalopathy (BSE) transmission, disposal of dairy and beef cattle mortalities by rendering either is not an option or is prohibitively expensive in many areas of the United States. On-site burial remains an alternative in many states, but impact on ground water quality is ...

A significant technological challenge is the search for appropriate disposal of hazardous waste, It is evident that technologies that are simple, practical and economical for use should be developed, and they should both safeguard public health and reduce environmental pollution. Temporal disposal on the ground surface is a common approach in many European countries, a technique that could cont...

To generate insights into how production of new items and remanufacturing and disposal of returned products can be effectively coordinated, we develop a model of a hybrid manufacturing–remanufacturing system. Formulating the model as a Markov decision process, we investigate the structure of the optimal policy that jointly controls production, remanufacturing, and disposal decisions. Considerin...

en c= m m — < m The Waste Isolation Pilot Plant (lVIPP) is the first operational repository designed for the safe disposal of transuranic(TRU) radioactive \vastefrom the defense programs of the U.S. Department of Energy (DOE). The U.S. Environmental Protection Agency (EPA) is responsible for certifications and regulation of the WIPP facility for the radioactive components of the waste. The EPA ...

The use of pharmaceuticals has led to considerable improvements in human and animal health. As a consequence of disposal also needs to be considered, making pharmaceuticals a waste management concern. While the disposal of waste pharmaceutical residues through the wastewater stream is widely studied, there are limited data on the disposal of unused pharmaceuticals. It is essential to ascertain ...

a study was carried out in a strip of a river and in a nearby well in the rainy and dry seasons to assess the impact of tobacco waste disposal on the roadsides. there were significant seasonal variations in the concentration of nicotine being higher (p

Solid Waste Management (SWM) system in Bhopal has deteriorated recently to the point that only limited waste collection is undertaken in certain urban areas and disposal is largely to uncontrolled dump sites. In this study, the technical, economical, and environmental aspects of three SWM scenarios were investigated aiming to compare the scenarios and select the most appropriate one for impleme...

Background Caffeine and chlorogenic acid are two compounds in green coffee beans that alter blood glucose disposal and insulin sensitivity. Caffeine has been shown to decrease glucose disposal and insulin sensitivity when taken 60 minutes prior to an oral glucose tolerance test in humans, whereas chlorogenic acid has been shown to increase glucose disposal and insulin sensitivity in humans. The...

This paper reviews documented environmental effects experience from the disposal of solid waste materials in the U.S. Selected case histories are discussed that illustrate waste migration and its actual or potential effects on human or environmental health. Principal conclusions resulting from this review were: solid waste materials do migrate beyond the geometric confines of the initial placem...
