The purpose of this study (Technical Assessment) is to recognize how to convert solid waste materials into composting in North Syria, Non-State Armed Group (NSAG) controlled areas, and indicates the produced mass of the compost per capita, the assessment showed that: the weather condition in the north of Syria is suitable for converting the domestic solid waste into compost within 99-111 days at the temperature: 10-350C, The volume of the compost is about: 49.3%-55.2% of the volume of the solid waste before composting, that means the composting by housed hold could minimize the volume of solid waste to 44.8%-50.7% so the environment pollution of the and cost of dealing with the solid waste will be low, in general, the loss of mass and volume will have occurred during the composting process. The productivity of compost of each family is about: 0.69 – 0.8 kg/day and the production per capita is 0.08-0.129 kg/day, and the density of the compost 851.6-933.8 kg/m3. Only 6% of people who are involved in the questionnaire in Aleppo and Idleb governorates have no access to farmland whereas 94% of people have access to the farms and about 75% of people who have access to the farmland use fertilization, 92.35% of the interviewees reported that they are not familiar with the processes of converting the domestic solid waste into compost, whereas 7.65% reported that they are familiar with the composting process, and 57.1% of them reported that they were interested to convert the solid waste into compost and 42.9% of them expressed that they were not interest of composting; data shows the reasons why people were not interested in converting the solid waste into compost:13.3% do not have the composting tools, 67.2% are not familiar with composting processes, 12.8% do not need compost and 6.7% of people need a long time to perform the composting.
