00:00Singapore appears spotless. So where does its 2,000 tons of daily trash actually go?
00:06While landfills keep growing in many countries, Singapore has mastered reducing its waste volume
00:11by 90%. Every single day, over 3,000 trucks haul the city's garbage to special collection points.
00:19From there, the waste heads to plants that operate 24-7. Inside these facilities, the trash is burned.
00:26The heat generated by this burning process is captured and turned into electricity,
00:31powering entire neighborhoods. You might think the smoke from these plants would constantly block
00:37the sun, but that's not the case. Before any emissions are released into the air,
00:42they go through rigorous multi-stage filtering. This cleaning process makes the output air
00:48remarkably clean. All that's left after burning is a fine, light gray ash. This ash is carefully
00:54collected and shipped to Singapore's only official landfill, an artificial island called Semakau.
01:01Eventually, they plan to use this ash in construction projects,
01:04things like making paving stones, for example.
