INTEGRATED SOLID WASTE MANAGEMENT
An amount of 30,000 tonnes per day is expected to be
accumulated in Malaysian country in the near 2020 year.
Past decisions on waste management strategy and the
structure of waste management system have relied on the waste management
hierarchy. The hierarchy gives the following order of preference i.e. waste
reduction, reuse, materials recycling, composting, incineration with energy
recovery, incineration without energy recovery and landfilling. However, such
use of a priority list for the various management options has serious
limitations. Technically, the
hierarchical concept is far from scientific for the reason that none of the
management technology resulted in an optimal result. Due to this reason, there
is a need to radically improve solid waste management practices in Malaysia. Recently,
the Malaysian Government Policy has
outlined an emphasis on the policy and the management of solid wastes in which
it has to be implemented in holistic and well-planned manners. In order to implement the strategy, the
concept of integrated solid waste management that take into consideration the
impact analysis of each of the waste management option need to be considered. The advantages of implementating holistic technique of solid waste
management are the concept able to
contribute to the economic increase of a country and reduce the impacts of the
pollutants to the environment.
The integrated management system combines both
holistic and sustainable environmental-friendly approaches. The system starts
from the initial point of accumulation until the final point of disposal
(disposal sites). The in-between components between the two points according to
its order are the pre-sorting technology, collection, central sorting,
recycling, biological treatment, thermal treatment and finally landfilling. In
order to produce an efficient, systematic, technologically-enhanced and
innovative management system, it is necessary to combine all the existing technologies
and for each of the technology, various techniques and approaches are further
suggested in order to ensure that each component is functioning effectively
