Greenhouse gas (GHG) emissions from municipal solid waste (MSW) in Oman

In Oman, the total quantity of MSW stood at 2.0 million tonnes/year. The emission from this waste is estimated at 2,989,467 tonnes/year (CO2 Equivalent). This article proposes different frameworks that considered landfilling, composting, and recycling of MSW and compared the emissions of these frameworks. The framework (F2) which includes landfilling and composting process for the organic waste which normally goes to landfills results in an increase of emissions by 7% as compared to current practice. likewise, the samples of MSW collected in Oman show a good amount of recycling waste. The framework (F3) which uses the landfill, composting and recycling reduced the total GHG emissions from 2.98 million tonnes/year to 2.95 million tonnes/year (CO2 Equivalent); resulting a total reduction of 1% in emissions. While composting increases the emissions but adopting composting and recycling can reduces the burden on landfills and can promote agricultural and industrial activates
