Generally, such refuse is regarded as useless material that is unwanted and therefore discarded. The New Edition Concise English-Dictionary [15] explains that “waste” is “anything or anyone rejected as useless, worthless, or in excess of what is required”. But Byrne [16] was more comprehensive with his description of waste, when he stated that waste is material, which has no direct value to the producer and so must be disposed of. This could be why Bailie et al. [17] insist that “for practical purposes, the term waste includes any material that enters the waste-management system”. A waste-management process and pertinent system are an organized programmes and central facility respectively established, not only, for the final disposal of waste but also for recycling, reuse, composting and incineration. From the foregoing, it is apparent that materials enter a waste-management system when no one who has the opportunity to retain them wishes to do so.
