ABSTRACT

Solid waste management is becoming increasingly difficult as traditional land­ fills are becoming scarce and, more importantly, environmentally undesirable. Among the problems is the ever-increasing volume of polymer wastes [1-4]. Most of the solid polymers (plastics) are used as protective coatings, structures, and

packagings. They are designed and manufactured to resist environmental degrada­ tions, including biodegradations. Since plastics are more economical than metals, woods, and glasses in terms of manufacturing costs, weight-to-strength ratio, and the amounts of energy and water required, as well as in most cases causing less environmental harm, the use of plastics is likely to increase. This makes polymer waste management an urgent problem, needing environmentally compatible and friendly solutions, both short and long term, as soon as possible [ 1-3].
