The disposal of clinical wastes is often poorly conducted and inadequately supervised despite the publication of clear and definitive working guidelines and the introduction of increasingly stringent legislative control. The move away from landfill disposal of clinical wastes, and the further development of high temperature incinerators able to meet increasingly tight emission limits, is to be ...
firehouse, technical assistance could be solicited. For example, the county supervisor of the Farmers Home Administration might be called in to discuss that agency's requirements regarding financing for public water and waste disposal facilities. Farmers Home is authorized to provide financial assistance to rural "associations" for the purpose of installing community domestic water and waste sy...
In the recent past, household hazardous waste has become an issue to more and more communities. In an effort to control the pollution generated within a household, various methods have been set forth in col lecting and disposing of these wastes. Unfortunately, all too often the hazardous waste collection days are poorly attended, and the costs become prohibitive when measured against the amoun...
used pet bottles disposal is an unsolved environmental problem, and there are many efforts for finding an applicable solution for it. many researches have showed that the degradation rate of the polymers increase with the smaller size of fibers. this work was carried out to convert used pet bottles into nanofibers by melt-electrospinning method. uncolored, washed and chipped pet bottles and the...
Sewage sludge was used as fertilizer in agriculture in Switzerland since the begin ning of modern waste water treatment. During the last 40 years several difficulties arose with the agricultural use. The problems with pathogenic germs could be solved with a prepasteurisation. The contamination with heavy metals was reduced during the years but remained a cause for concern. The fear of mad cow d...
Swiss Legislation requires for all types of radioactive waste the safe and permanent disposal in deep geological repositories within Switzerland by stipulating a step-by-step procedure for site selection and licensing of the disposal facilities. Each step requires safety considerations or safety analyses which are reviewed by the Swiss Federal Nuclear Safety Inspectorate. The principle steps of...
In recent years, geological disposal of radioactive waste has focused on placement of highand intermediate-level wastes in mined underground caverns at depths of 500–800 m. Notwithstanding the billions of dollars spent to date on this approach, the difficulty of finding suitable sites and demonstrating to the public and regulators that a robust safety case can be developed has frustrated attemp...
In this study, we analyze an inventory system facing stochastic external demands and an autonomous supply (independent return flow) in the presence of fixed disposal costs and positive lead times under a continuous review replenishment– disposal policy. We derive the analytical expressions of the operating characteristics of the system; and, construct the objective function to minimize the tota...
Since the world's first disposal of radioactive waste in Oak Ridge, Tennessee, in 1944, considerable experience has been acquired in the field. The first disposal site — intended for "actively contaminated broken glassware or materials not sufficiently clean to be used in other work" — was a simple trench filled with unconditioned waste located on the Oak Ridge site. Similar approaches were ado...
Carcass disposal: lessons from Great Britain following the foot and mouth disease outbreaks of 2001.
The foot and mouth disease (FMD) outbreak that occurred in the United Kingdom in 2001 was of an unprecedented scale and severity and presented a massive logistical challenge to Government. Over 6.5 million animals were slaughtered and disposed of, over 4 million as a direct result of disease and a further 2.5 million on welfare grounds. On-farm burial and on-farm burning were the principal rout...
