Unused material

The results of the tests to determine the calorific power show satisfactory values for coprocessing, be it for mixed materials, otherwise unusable material from separation or plastics in general. As observed by [6], the level of chlorides is closely related to the quantity of plastics in the mixture, and also depends on the type of plastic. 

At close-out of the Trial Site following termination or expiration of this Agreement the NHS Trust shall immediately deliver to the Sponsor all Confidential Information and any other unused materials provided to the NHS Trust pursuant to this Agreement. 

Low utilization means that at the breakpoint, i.e. when the operation of the bed is stopped, the portion of the solid material in the bed used during the service time is low, which is undesirable. Especially, if the material cannot be regenerated, low utilization means that the unused material is lost. 

In addition to features similar to those for conventional materials, SUDICRETE products are remeltable without degradation or change in properties and thus waste and unused materials can be recycled by crushing and feeding back to the mix cycle. 

Data for some filter media are shown in Table 11.6. Although these porosities and permeabilities are of unused materials, the relative values may be useful for comparing behaviors under filtration conditions. Permeability Kp normally is the property... 

For instance, urea, the product of protein digestion from which the term urine is derived, must be removed. Other waste products of metabolism must be removed. Any toxins produced by bacteria must be removed. Any drug residue or other unusable material must be removed. Any excess hormone must be removed. Glucose, on the other hand, should not be eliminated and proteins should not be secreted. Vitamins need to be saved, as does calcium and a certain amount of sodium and other minerals. However, water must be regulated. Too much water in the blood would be bad because if blood were too dilute, then not enough nutrients would be transported to the cell. If blood had too little water, then the physical process of pumping the blood around would be... 

Unused material must never be returned to the stock bottle but thrown away into the crock or sink. 

The custom processor has therefore got to achieve a higher standard than the in-house recoverer as far as a solvent s smeU is concerned. If a smell is imavoidable, as it is in most cases, the standard to be reached is that of the virgin unused material, a sample of which is sure to be in the possession of the potential commercial buyer. 

A related issue is decreased quality of some streams of recycled materials. Manufacturers of recycled paper seem to have the most problems, reporting that the additional contamination causes economic harm to their operations. Not only must the receiving facilities pay for unusable material, they also have to do more processing and use more chemicals to remove the contaminants. It has been estimated that mUl operation costs increase by about 8 per ton when fiber from single-stream rather than dual-stream MRFs is used. ... 

Economics. For high volume low cost materials such as plasterboard it is more economically viable to dispose of unused material at the end of the construction project, and re-order for the next project, than to store and carry unused materials over. 

The amount of combustible materials to hand at a worksite should be kept as low as is reasonably practicable. Limit materials to half a day s supply or a single shift and return unused materials to the stores. Always choose the least flammable materials and keep site stocks down as far as possible. 

Stores should keep up-to-date records of all disbursements and should actively pursue the recovery of tools, equipment, and unused materials. 

In underground operations, powder chests or day boxes often are used to transport explosives from the magazine to the blasting area. These boxes should always be locked or attended by authorized personnel. At the end of each shift, all unused materials in the day box must be returned to the storage magazine.
