Radiation Processing Of Waste Polymers

,

Management of solid waste is an important problem, which is becoming progressively worse as a by product of continuing economic growth and development. Development of technologies for reducing polymeric waste, which are acceptable from the environmental standpoint, and which are cost effective has proven to be a difficult challenge due to complexities inherent in the reuse of polymers The ability of ionizing radiation to alter the structure and properties of bulk polymeric materials, and the fact that it is applicable to essentially all polymer types, irradiation holds promise for impacting the polymer waste problem. Radiation Processing is the large-scale use of such ionizing radiation for modifying and synthesizing materials. In view of recycling of polymers, the main possibilities for use of radiation include enhancement of the mechanical properties and performance of recovered materials or polymer blends, principally through cross linking, or through surface modification of different phases being combined; treatment causing or enhancing the decomposition of polymers, particularly through chain scission, leading to recovery of either low molecular weight mixtures, or powders, for use as chemical feedstock’s or additives and production of advanced polymeric materials designed for environmental compatibility. Radiation processing represents a minor yet significant technology in recycling of waste polymers applications. This paper provides an overview of radiation processing of waste polymers with emphasis on current advancement in radiation modification of waste polymers. The recent developments on radiation modification of Ethylene Vinyl Acetate(EVA) /waste arylonitile-butadiene rubber (w-NBR) will be discussed in detail.
