The most of the developing countries as they can’t

The rapid increasing population
and its associated waste generation increase are causing a lot of problems in
most of the developing countries as they can’t cope with this sudden increase.

Providing a proper solid waste
management is one of the most import services the government has to provide to
its citizens. It single handedly takes up a huge portion in the budget list. Lack
of technical skills among the government and municipal authorities is one of the
technical factors that affect the system. And they fail to provide a better
solid waste management because they also lack financial means.

The current solid waste
management techniques used in most of the developing countries are landfills
and incineration. Open dumping of waste is still practiced is some of these
developing countries. The problem that arises with incineration is that it is
not cost effective and it requires high amounts of energy. The burning of
various components of the waste can also cause air pollution. The ash produced
from incineration has to be disposed well. When it comes to landfills, it not
only requires land availability but also causes health hazards to the people
living around the land. Open dumping creates a breeding spot for a wide variety
of disease causing insects. It does produce a huge quantity of methane gas
which is a deadly greenhouse gas.

In order to overcome these
problems large number of studies were conducted from 2005 to 2011 to review the
solid waste management techniques and the problems associated with them in
these countries. From these reviews, the Integrated Sustainable Waste
Management Model was introduced. This model analysed the various sectors from
the waste generation at the household to the collection stage to the dumping
stage and finally the recycling.

The waste generated in every
household was found to be greatly affected by the size of the family, education
level and family income. The waste disposal choice here depended on the supply
of adequate waste facilities for example supply of separate bins for
biodegradable and the non-biodegradable waste. Even the distance to these
facilities played a role in the disposal choices. In these countries, reducing
the waste at the source are always discussed by are not incorporated. The
collection stage also had numerous problems such as the lack of enough collection
trucks, poor road quality and improper bin collection systems.  And providing a high efficiency of collection
service takes up a huge portion in the solid waste management budget. Recycling
of the waste greatly depends on the degree of separation and the amount of
other materials that are required for the process. Most of the waste in these
countries, rather than being separated at the source is separated at the
dumping ground. This can cause the recyclables to be contaminated which can
cause a reduction in their market value.

The people who collect waste in
most of the developing countries are looked down upon; they are considered to
have a low social status. This situation lowers their motivation to do a good
job.

The main problems of solid waste
management in developing countries are as follows: 1) inadequate
service coverage and operational inefficiencies of services, 2) limited
utilization of recycling activities, 3) inadequate landfill disposal, and 4)
inadequate management of hazardous and healthcare waste
