Singapore has impressive public waste-management systems, but there's just one problem - its residents aren't pulling their weight when it comes to household recycling.
The land-scarce Asian city-state generated about 8,400 tons of solid waste a day in 2015, but has just one offshore landfill space to bury all its trash. The landfill "island," called Semakau, was created in 1999 and extended in 2015, with enough space to meet Singapore's waste disposal needs until at least 2035.
Singapore gets by with so little space for rubbish through an innovative waste management process, in which it recycles about 60 percent of its solid waste and incinerates 38 percent of its total waste in waste-to-energy plants. Just 2 percent of the non-incinerable solid waste and the ash from the incinerator plants are buried in the landfill.
But this isn't due to a heroic environmental effort from Singaporeans. Households recycled just 19 percent of their waste in 2015, down from 22 percent in 2010.
