The process of collecting and transporting solid waste is the first and fundamental issue in the management of solid waste as it is the most economically expensive operation, in which its expenses in the process of system of municipal solid waste man
agement (MSWM) reaches about 60-70% of the total expenditure. This process starts from placing waste in containers till unloading these containers in transportation vehicles and then carry them to transfer stations or final disposal sites.
The fees of collection and transportation can be reduced through the selection of the optimal path, and thus obtaining many economical benefits.
In this research, the applications of geographical information systems (GIS) have been used in order to choose the optimal route for waste collection, transportation and transference in the city of Lattakia, Where a database has been designed which included mainly the streets, bridges and tunnels, it also included residential areas serviced by waste containers, and the process of linking them to each other took place by using the techniques of GIS in order to choose the best economical and timetable ways for the traffic of vehicles to collect and transport the waste, which contributes practically and effectively in improving the activities of municipal solid waste management in this city.
The research aims to determine the water Quality Index for the Lake of 16 Tishreen Dam. To achieve
this aim, we have carried out different periodical physic-chemical and bacterial measurements on the lake
water. The samples were taken at five sites
along the lake for a period of one complete year. The indicators
that have been measured are: Temperature, Turbidity, PH, EC, DO, BOD5, NO3, NO2, NH4 ,PO4, F.C.
Measurement results were represented diagrammatically, and compared with the Syrian Specification
Standards for portable Water. The lake was classed according to these Indices: Malays quality index,
Canadian Indices (NSFWQI), (NEWWQI). The Lake was Classed according to these indices as following:
from third grade at all locations (Malays Index), from second grade at the middle lake and from a third grade
to all other locations (NSFWQI), and from second grade at all locations (NEWWQI). According to this
indices the water is not good for drinking and needs treatment. The Productivity of the lake was determined.
The Lake is Eutrophic according to TN,TP in the middle but Hypertrophic according to TN,TP in all other
locations.
In developing countries, including Syria solid waste sector contributes to the
emission of greenhouse gases, mainly methane, due to the lack of methods of integrated
management of solid waste in these countries.
The objective of this research is t
o study the feasibility and effectiveness of
mechanical biological treatment of municipal solid waste in a way to reduce methane gas
emissions compared to the way the indiscriminate dumping of municipal solid waste. In
order to reach this goal is the use of the formula contained in the guidelines of the
International Panel on Climate Change (IPCC) in account the emissions of methane from
municipal solid waste sector in the Syrian Tartous in the case of landfilling of municipal
solid waste generated by the province during the years from 2010 until 2015 in random
landfills. In order to compare the account is an assumption that the same amount of
municipal solid waste generated by the province during the years from 2010 to 2015 have
been treated in accordance with the mechanical biological treatment method. It was also
calculate the amount of methane emitted from municipal solid waste entering the
integrated waste treatment center in the Province of Tartous within one year from the
beginning of June 2014 until the end of May 2015, using mechanical biological treatment
method.
This study concluded that the mechanical biological treatment for municipal solid
waste significantly reduces the amount of methane emissions from solid waste sector
compared to the landfill, where the percentage of reduction in the emission of methane
93%.
