The enormous difficulties emerging with the management of the increasing amounts of municipal wastes in the municipal city of Kumasi, Ghana’s second largest city with a population of 1,2 million people have underscored the need to explore the possibility of source sorting the wastes from the households and develop a decision support system for the planning and management of the wastes.

The study is a pilot project in the sub-metropolitan area of Asokwa with selected households of first, second and third class residential areas that have been supplied with three separate identifiable waste bins in which to sort organic, plastic and rest wastes. An environmental education was undertaken to sensitize the households of the need and benefits of source separation. Collection of the wastes is undertaken four times a week.

 The wastes are analyzed to determine quantity, generation rate as well as the efficiency of separation. The organic wastes are composted while the plastic wastes are sold to a waste plastic recycling company. The benefits derived from these exercises are to be made available to the respective households as proof of the benefits and to further motivate them.

On a broader scale, the study will develop a decision support system that will enable the metropolitan municipal assembly of Kumasi to take informed decisions with regard to the introduction, integrated and cost efficient management of the household wastes and serve as a reference for other municipalities in Ghana.
