Abstract:
Recently, the world has begun to experience depletion in energy resources and this issue
has become a major concern. Sudan faces a problem with limited fossil fuel resources and
an increase in waste accumulation as population growth and economic development play
an important role in increasing solid waste generation in addition to increasing energy
demand. Sudan is one of the most densely populated countries in Africa, with an annual
growth of 2%. We find that about 20% of the population of Sudan is located in its capital
(Khartoum) and its population is about 8 million, according to the census of the current
year. Waste is a must-have product and can be a valuable concern or resource that can be
used through waste to energy technologies. This study aims to develop the engineering
waste dump in the Faculty of Engineering, Sudan University of Science and Technology,
which was designed in October 2017 in the form of a trapezoid with dimensions (2 * 1.75
* 1.4) to provide a suitable technical solution for both the waste and energy sectors by
changing the waste layers and collection tubes Gas, organic waste was used only and then
began monitoring landfill gases and measuring the methane content that can be produced
from the total landfill gases. Periodically moisturizing of the landfill was carried out.
Water is considered an auxiliary factor for the bacteria responsible for the production of
methane and previous studies prove that. A questionnaire was also conducted to analyze
and evaluate waste management in Khartoum and to highlight waste dumps in Khartoum
and compare them with the standards of engineering landfills. The study proved that the
experimental landfill can be an energy source, as the methane ratio reached 68%; which
is a good flammable percentage, and the pH of the landfill was 7.7; which is suitable for
bacterial growth. The study also showed the weakness of the administrative system for
collecting, transporting and treating solid waste in Khartoum State and the extent of the
existing dumping sites. The study contains recommendations for improving management
and technical development of landfills.
