With the booming economy and increasing population, the accumulation of waste has become an
increasingly arduous issue and has aroused the attention from all sectors of society. Hong Kong which
has a relative high daily per capita domestic waste generation rate in Asia has not yet established a comprehensive
waste management system. This paper conducts a review of waste management approaches
and models. Researchers highlight that mathematical models provide useful information for decisionmakers
to select appropriate choices and save cost. It is suggested to consider municipal solid waste
management in a holistic view and improve the utilization of waste management infrastructures. A
mathematical model which adopts integer linear programming and mixed integer programming has been
developed for Hong Kong municipal solid waste management. A sensitivity analysis was carried out to
simulate different scenarios which provide decision-makers important information for establishing
Hong Kong waste management system.
