Trash is a waste that is made in the process of production and transportation or is junked by becoming extinct of their economic value after using several products in the routine life. However, of the population more than 2 / 3 live in urban by increasing urban concentration because of the rapid industrialization. Also, as the economy grows a lot and a rich economic

Management challenge in Contracting
Challenges for public agencies
Loss of control
Reliance on contracting may put the government in a vulnerable position where essential services are concerned and lead to some loss of control over the services they purchase.
Excessive costs
Experienced service providers may have an information advantage over the government when new services are contract

Who is interested in the process?
Alongside traditional methods of processing and preserving food, the technology of food irradiation is gaining more and more attention around the world. Although regarded as a new technology by some individuals, research on food irradiation dates back to the turn of the century with the first USA and British patents being issued in 1905 for the use of ionizing
