The study focuses on assessing the potential and economic efficiency of reducing greenhouse gas (GHG) emissions from organic solid waste treatment technologies, including: Non-recovery landfill, landfill and gas recovery for power generation (applied in Nam Son disposal site) and composting (applied in Cau Dien disposal site) in Hanoi. Research results illustrate that, the treatment of 1 ton of organic domestic waste by landfill without gas recovery and landfill with gas recovery need to cover losses about $14.2 USD and $0.9 USD, respectively. While application of composting technology makes a profit about $5.1 USD. Composting had the potential to significantly reduce GHG emissions and used the product after the treatment in commerce to have capital for reinvestment but it was also planned by Hanoi People’s Committee for waste treatment in the future. However, the roadmap for converting to composting technology should be implemented from 2030.
