Natural resources methods

Yet, the development of processing and modification methods is not finished. Further improvements need to be expected so that it might be possible to substitute technical fibers in composites even more widely. Natural fibers are reusing raw materials and they are recyclable. When recognizing the need for recycling and preserving natural resources, such a substitution is very important. 

As crude oil resources decrease, the oil industry demands more sophisticated methods for the exploitation of natural resources. As a result, the use of oil field chemicals is becoming increasingly important.

In order to determine chemical elements in soil, samples of the soil must undergo a solid-liquid extraction. Sometimes the extracts resulting from this procedure have analyte concentrations that are too high to be measured accurately by the chosen method. Therefore, they must be diluted. At the Natural Resources Conservation Service (NRCS) Soil Survey Laboratory in Lincoln, Nebraska, an automated diluting device is used. Using this device, the analyst accurately transfers aliquots of the extract and a certain volume of extraction solution to the same container. This dilutor may also be used to pipet standards and prepare serial dilutions.

Morphine is presently the standard analgesic by which all the others are compared, and whose alternative methods of synthesis are still being developed [3-6], Nevertheless, synthesis of morphine is not economically practical, since it is much cheaper to obtain from natural resources. 

Bionolle is a typical biodegradable plastic. Currently, each raw material is made from petroleum, but we are developing more environmentally friendly green plastics. The first approach is to produce plastics from monomers such as succinic acid by biological methods. The second approach is to make hybrid compounds of Bionolle and natural resources like starch. The typical chain of materials for Bionolle is shown in Fig. 1.

Important to note is the asymptotic behavior of Equation 13.14, which is clearly seen in Figure 13.17. This nonlinearity causes the abundance factor Oi to be more sensitive at small depletion times and less sensitive at large depletion times, which is in accordance with our intuitive judgment. When comparing two different natural resources, the difference between 100 and 1000 years of depletion time is much more important than the difference between 1 billion and 10 billion years. The latter time scales are both so large that it is almost equally unlikely that the depletion of either one of these resources will cause a process using them to become unsustainable. Hence, the nonlinear behavior of Equation 13.14 brings some common sense to the quantification method.

On November 8, 1978, it was reported in the Wall Street Journal that "The only active commercial coal gasification project has been halted by American Natural Resources Co. and four gas-pipeline concerns. The suspension of design and engineering work on the 1.4 billion project in North Dakota followed the failure of attempts to settle a controversy over the method of financing the project which had delayed federal approval required before work could proceed."...

Another aspect of concern is the limit of resources in the world. Some decades ago, the term recycling was almost unknown. At the present time recycling is a household term and recycling of metal products, paper and plastics has been recognized for the important role it plays in conserving our resources. We have reached a level of maturity to be able to recognize that our natural resources are limited and finite in our world, and that methods to conserve these resources by recycling and other methods have a prominent role to play. 

Which effect assessment method should be applied in a particular situation depends on the nature of the mixture problem at hand. Because the diversity in assessment methods is large, it is important to clearly describe the problem. For example, derivation of a safe level for a proposed industrial mixture emission requires a different approach than the prioritization of a number of sites contaminated with mixtures. The former problem requires the assessment of realistic risks, for example, by the application of a suite of fate, exposure, and effect models, whereas the application of a simple consistent method suffices to address the latter problem, for example, a toxic unit approach. A successful and efficient assessment procedure thus starts with an unambiguous definition of the mixture problem at hand. The problem definition consists of the assessment motive, the regulatory context, the aim of the assessment, and a structured or stepwise approach to realize the aim. Elaboration of the problem definition is an iterative process (Figure 5.1) that strongly depends on factors such as resources, methods, data availability, desired level of accuracy, and results of previous studies. 

The straight-line method may be applied on the basis of units of production or predicted amount of service output, instead of life years. The depreciation may be based on miles, gallons, tons, number of unit pieces produced, or other measures of service output. This so-called unit-of-production or service-output method is particularly applicable when depletion occurs, as in the exploitation of natural resources. It should also be considered for properties having useful lives that are more dependent on the number of operations performed than on calendar time.
