Abstract

This study seeks to compile data on the worldwide established technologies and systems for waste recycling. Waste recycling is currently seriously considered as an integral part of solid waste management in many parts of the world. A vast number of options ranging from small scale decentralized to larger scale centralized plants may be adopted. The identifiable waste reuse schemes worldwide have been critically analyzed in this paper. Peer-reviewed journal papers, conference papers and information gathered from the internet formed the basis of this review paper. The available cost data were also furnished. This paper, therefore, as a whole adds to both technological and economical aspects of the knowledge-base of waste recycling schemes. Besides the technical aspect, issues like public acceptance, economic and hygienic risks etc. should be taken into account to counter the obstacles facing implementation of waste recycling.
