Greenhouse Gas Emissions Reduction from Biodrying MBT in Tropical Climate

Abstract

Landfill management in Asian countries mostly go to final disposal site. Due to lack of Municipal Solid Waste (MSW) recycle and utilization, nearly 100% of MSW was end up with landfill. High waste generation rate makes landfill rapidly full. From MSW characteristics, a half of MSW in Asian countries consist of organic materials that show high potential of Greenhouse Gases (GHGs) generation. In the tropical region is clearly distinguished from dry period (winter and summer seasons). This climatic condition would affect to greenhouse gas emission during biological process. The study demonstrated the GHG mitigation potential of Biodrying MBT system. As compared to conventional landfill operation, MBT Biodry-I and Biodry-II significantly reduced GHG for 88% and 84%, respectively. The result indicated that the biodrying MBT show the important rule to mitigate environmental impact in terms of global warming. The dramatically decreased of MSW volume to final disposal site improves the problem of land use that happened in some area currently. Additional benefit from this technology is the utilization of MSW. The SRF business could be promote to local authority in Asian countries in terms of compensate from waste management activities.
