METHANE FERMENTATION TECHNOLOGY COMBINE WITH GENERATOR. SOLUTION FOR DOMESTIC WASTE TREATMENT IN LARGE URBANS, CONTRIBUTE TO CLIMATE CHANGE INHIBIT

Abstract

Based on the existing condition of the treatment of domestic solid waste in Vietnam and the researches of the potential development of CDM in the national and international areas, the study finds out that if anaerobic digestion technology is applied, 3.6 million kWh per day is produced from 21.500 tons/ day domestic solid waste, which is composed of 70 – 85% organic material. Thereby, this study brings out a profit of 160.000 USD per day. Moreover, concerning emission reduction, research results from Omid tayyeba in SWECO show that, anaerobic digestion technology reduces 1,6 times more than composting technology and 1,5 times more than landfills technology which have electricity production system from gas. Based on that, the study suggests that anaerobic digestion technology should be applied into two periods and combined with electricity production in order to maximin methane generation in the short time and prevent the use of unrenewable fuel. This helps to reduce GHGs emission and actively adapt to climate change in the general trend of the world.
