In this research article, an Integrated Solid Waste Management Model is developed using Integer
Linear Programming (ILP). Integrated into the current solid waste management programme (of waste collection
and dumping) are compost and recycling plants. An objective function consisting of fixed and variable costs,
transportation cost and environmental cost/credit is developed subject to capacity, mass balance and
environmental constraints. Two case studies were carried out using the model. In the first case study, the model
was tested with waste collection from three sources/zones in Accra Metropolitan Assembly (AMA) and
dumping of waste at current three landfill sites. In the second case study, a new landfill site and a compost plant
acquired by Zoom Lion Ghana Ltd., were integrated into the model. The results show that the operational cost
for the Integrated Solid Waste Management model is close to that of the ‘’collection and dumping’’ programme
initially. With increased revenue per tonne of compost and/or increased proportion of waste converted to
compost, the overall operation cost reduces considerably in the case of the integrated solid waste management
model making it more efficient with reduced environmental pollution. This finding is significant because it
emphasizes the need to adopt integrated approach to solid waste management in the metropolis.
