Abstract: 

 The research aims to calculate the amount of compost resulting from fermentation of one ton of organic materials separated from the waste of Tartous Governorate, in addition to monitoring changes in temperature, air oxygen saturation, and humidity of organic matter during the fermentation process. The research was conducted at the Solid Waste Treatment Center in Tartous Governorate during the period (1/6/2019,1/8/2019), in the aerobic fermentation yard of organic materials separated from the rest of the waste, which passes through three stages: The first is physical, the second is biological (natural ventilation), and the third is final (maturation).The results showed that every one ton of coarse organic materials produces 400 kg of compost, and every one ton of soft organic materials produces 600 kg of compost. It was found that the resulting compost maintains good humidity during the fermentation period (month)(40-60)%,and its temperature reaches (60°C) during fermentation. Therefore, the sterilization process was achieved, and the dangerous pathogenic germs were eliminated. We noticed a decrease in the oxygen saturation rate with the increase in the biological fermentation time and that it reached the final ripening period with 60% humidity and moderate temperature and no unpleasant smell.

Keywords: Compost, Municipal Solid Waste, Fermentation    (composting) , organic waste- Oxygen saturation rate.
