Figure 7.5 Relationship between nonrenewable and recyclable resources.

The degree of availability of recyclable resources such as scrap and wastes is a widely varying parameter. By way of illustration, scrap can be classified as new scrap (or in-process scrap) and old scrap (or post-consumer scrap). The former, which constitutes the majority of scrap processed at present, is derived mainly from the wastes generated during metal production and fabrication, and can be reclaimed and recycled with relative ease. 

Heterogeneous composite materials made from waste or recycled components such as polyolefin polymers and wood fibers were shown to be made compatible by T. Czvikovszky through the use of small amounts of monomers that graft onto the two normally incompatible phases of said mixtures. These compositions demonstrated sufficient material properties to be used in the construction of truck and automotive components, such as door and side panels. To exploit the use of such recycled resources, process techniques in mixing and compounding had to be developed.

ABSTRACT How to exploit and utilize abolished mine has become a new issue of recycling resources in the world today. The explosion-proof design for coal robots which is used to detect the environment must be adopted. Based on a study of the necessity of the abandoned mine reuse, the wheel mine detection robot which designs for detecting the environment of abandoned mine is introduced. This paper is focus that the explosion-proof designs of the mine detection robots. The reference for the mine detection robots design will be provided in the future.

Reusables have an additional impact on the environment due to the laundering process. Water needs to be available for this process. After washing, water effluent is generated and needs to be treated so that the local municipality can re-use it. As such, water effluent is not waste bnt a recyclable resource. This is, in part, due to advances in lanndry chemistry that have virtnally eliminated concerns at water treatment facilities for handling this efflnent. ... 

In recent years, strenuous efforts have been made to conserve and recycle resources. Of major concern has been water due to its rising consumption and resultant shortage. Any discussion of water must include its domestic and industrial use. The treatment of waste sewage is the concern of sanitation engineers and will not be considered here.

As the resources and energy reserve of the earth are becoming scarce, Science/Technology must first minimize their consumption. Science/Technology must be employed to recover resources already consumed and released into the ocean and atmosphere, to recycle resources, and further to create new resources and energy supply. Also, technology to repair the damaged natural environment or to prevent its further devastation must be developed. 

Global wanning has become a major issue, and there is a move away from fossil resources toward recyclable resources, not only as energy sources but also as chemical feedstocks. Polyamines are used as intermediate materials in the production of synthetic fibers and fabrics. At present, they are mainly produced from petroleum by industrial chemical processes, but putrescine, spermidine, and cadaverine can all be synthesized biologically from arginine, ornithine, and lysine. These amino acids are produced industrially by fermentation. To obtain a higher polyamine yield and industrialize the process, we await a more detailed understanding of polyamine metabolism in bacteria. 

As such wood flour, used as a filler in thermoplastic composites, offers only modest, if any, reinforcement, but wood fibers can lead to superior composite properties and act more as reinforcing filler. Commercial wood flour is a by-product of the wood industry, often mechanically processed from waste materials such as planer shavings, chips, and sawdust, which are reduced to fine powders, with various grades available depending upon the particle size and the wood species. Wood (cellulose) fibers are produced through more or less complex defibrillation techniques, using raw materials from both virgin and recycled resources, and are different from natural fibers, such as jute, hemp, or sisal.
