Abstract: | Municipal solid waste management (MSWM) constitutes one of the most crucial health and environmental problems facing authorities
in the Arabian Gulf. Recent literature on current solid waste management (SWM) in Qatar has been reviewed in this paper, and
a focused study has been carried out to provide a review on the total amount of municipal solid waste generated, stored, collected,
disposed as well as the constituents of the waste. The analysis showed that Qatar produced around 2,000,000 tons of solid
municipal waste annually, corresponding to a daily generation rate per capita of about 2.5 kg. About 60% of MSW is organic
material and about 300 kg is composed daily. Landfill and composting is considered the most appropriate waste disposal techniques
in Qatar. Um-Al-Afai landfill has nearly 80% of MSW. Because of the increased migration in Qatar, there is a sharp rise in
the volume and also in the variety of solid waste. It is important to alleviate societal concerns over the increased rate
of resource consumption and waste production; thus, policy makers have encouraged recycling and reuse strategies to reduce
the demand for raw materials and to decrease the quantity of waste going to landfill. An example of the benefit of mechanical
recycling of plastics compared to land filling and composting was conducted by GaBi 4 life cycle analysis tool which showed
the benefits to the global warming and human toxicity. Recycling is the favored solution for plastic waste management, because
it has a lower environmental impact on the defined impact categories, from Global Warming Potential (GWP) and Human Toxicity
Potentials (HTP) indicators. |
