تولّدُ مدينةُ اللاذقيّة ما يقارب 800 طن من النفايات البلديّة الصلبة يوميّاً. و يتمّ التخلُّص من النفايات الصلبة في مكبّ البصّة العشوائي دون جمع الرشاحة أو الغاز المتولِّد. لذلك تمّ استخدام منهجيّة تقييم دورة الحياةLife Cycle Assessment (LCA) لتحديد استراتيجيّة إدارة النفايات البلديّة الصلبة الأمثل. من أجل إيجاد السيناريو الأفضل بيئيّاً، تضمّنت الدراسة أوّلاً تحديد التركيب النوعي للنفايات البلديّة الصلبة في اللاذقيّة، ليتمّ استخدام نتائج هذه الخطوة كمصدرِ بياناتٍ موثوقٍ به في إنشاءِ صورةٍ كاملة للأداء البيئيّ لأنظمة إدارة النفايات البلديّة الصلبة من منظور دورة الحياة. تمّ اختيار الوحدة الوظيفيّة للدراسة بـ 1 طن من النفايات البلديّة الصلبة المتولِّدة في اللاذقيّة. و شملت حدود النظام معالجة النفايات و التخلُّص منها باستخدام عدة سيناريوهات و هي: التخلّص من النفايات في المكبّ العشوائي، أو بالطمر الصحّيّ مع استرداد الغاز المتولّد، أو بوجود منشأة فرز و استرداد المواد قبل الطمر الصحّيّ و استرداد الغاز. و جُمِعت البيانات لهذه السيناريوهات من دراسةٍ ميدانيّة أُجريت في اللاذقية، و من المراجع و بيانات المكتبات الموجودة في برنامج SimaPro 8.3.0. و تمّ تقييم البيانات بمنهجية IMPACT 2002+ على فئات الضرر المتمثّلة بالتغيُّر المناخي و صحّة الإنسان و جودة النظام البيئي، و استنفاذ الموارد. و وفقاً للنتائج، تم التأكيد على أنّ مكبّات النفايات العشوائيّة هي أسوأ طُرُق التخلٌّص النهائي، و أظهرت عمليّة استرداد المواد أداءً أفضل مع الطمر الصحي و الاستفادة من الغاز المتولِّد، إذ يُعتبَر السيناريو الثالث بمثابة حلٍّ نحو تحسين الاستدامة للتغلُّب على مشكلة إدارة النفايات الحاليّة.
Latakia is a Syrian city that generates approximately 800 tons per day of municipal solid waste MSW, and the final disposal of MSW is in Al-Bassa open dump with no biogas capturing or leachate collection systems. Thus, a life cycle assessment approach LCA was used to determine the optimal strategy of municipal solid waste management. to find the most eco-friendly scenario, first, the composition study of MSW was conducted in Latakia. The results of first step are to be utilized as a reliable data source in establishing a complete picture of the environmental performances of municipal solid waste management systems with a life cycle perspective. The functional unit of the study was selected as one ton of MSW generated in Latakia. System boundaries included treatment and disposal of MSW using different scenarios: the open dump of waste, sanitary landfilling with gas recovery, and a material recovery facility MRF combined with a sanitary landfill and gas recovery. Data on the process was gathered from a field study conducted in Latakia, and from SimaPro 8.3.0 literature and libraries. The data was evaluated with IMPACT 2002+ methodology and the assessed environmental impact categories were climate change, human health, ecosystem quality, and resources. According to the results, while open dumping has been confirmed as the worst waste final disposal method, landfilling with gas recovery and material recovery facility showed better performance and is considered as a solution towards improved sustainability to overcome the existing waste management problem.

The problem of waste is getting worse day by day, which may represent a heavy burden on municipalities, that they are unable to process it in most situations. Man is primarily responsible for the waste form, and any scheme for management municipal so
lid waste most take into account the role environmental awareness among the citizens of north sides: the first is to reduce the amount of waste produced through improving people's behavior's and their dietony habits.
The second by working to strengthen its role in contributing to with the municipality in sorting and recycling and willingness to buy recycled good, which contributes to ease costs, and thus improve the management.
The aim of this research to identify the degree of presence environmental awareness about the management of solid waste in the province of Lattakia from the point of view of the mushers of research sample. And to identify the differences in their views depending on the variables studied (sex gender, educational level, place of residence). Research Applied on a sample of the population of the province of Lattakia that number had reached 280 people. The researcher used the questionnaire, which was relied upon in reaching the results of the study, was to ensure the stability of the resolution in two ways: first way retail midterm has reached stability coefficient (0.829), and the second method equation Cronbach alpha was the reliability coefficient was (0.793), a transaction firming acceptable statistically. The study reached the following conclusions: the presence of environmental awareness about the seriousness of solid waste on our lives and consider it the source of contamination and disease. And the existence of a social willingness to contribute to the management of solid waste as sort of domestic or work in environmental associations. The environmental awareness is spreading in the province as a whole, but noted concern for the environment in the city, most of the countryside. As environmental awareness associated cultural level where it was noted the high level of awareness among the educated classes more than illiterate. It has been observed is that to the environmental awareness is equally between males and females.
The research found the most important proposals : attention to publish more environmental awareness among community groups is an educated in addition to spreading the culture of voluntary work in the field of environment an educated.
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%.
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.

In this study, the effect of temperature on volume strains in three
types of local clay soils was studied after adding different percentages of
sand for each soil (10%-20%-30%40%-50%) when temperatures change
from (20-60)° C to be used as liners i
n solid waste landfill sites . The
results of the study showed that the mixing of sand with the clay played a
key role in reducing the magnitude of volume strains between (24-27%)
of the value of strains.
