Solid Waste Management for Environmental Protection. A Case Study of Accra (Ghana)

Abstract

For many years now, the general sanitation of Accra has posed many challenges to the Accra Metropolitan Authority (AMA). With the growing population- of Accra now standing at about 20% of the' population of Ghana, one of the most demanding aspects of the problem of the growth of Accra has been with its solid waste management. What has brought this particular problem into sharp focus is the need to develop a tourism industry in Ghana. One way to meet this challenge is to map in a cost-effective privatization policy for the daily collection and disposal of all the solid waste. Protected economic trends in Ghana indicate that tourism as an industry has a good potential and pour sanitation can impede the growth of tourism, 11 is mandatory that no effort be spared to Meet the challenge posed by the solid waste disposal problem in Accra. Further to this, such a politer have been proposed, the heart of which is a mathematical model of the Accra solid waste collodion tend disposal system. The model was redenied and solved as a transportation optimization problem.

To further exploit the economic potential of the huge amounts of solid waste generated in and around Accra (which presently stands in the order 4800 tons a day). Its Lc proposed that the waste he recyclized. A mathematical model of the recycling process is presented as a linear programming problem. A discussion to the solution of the model has been presented.
