With regard to treatment methods for waste, including residential and business wastes, 10.3% of waste was buried, 6.3% incinerated, 82.4% recycled and 1.0% discharged into the sea. Although the percentages of waste treated by incineration or recycled have been increasing annually, the rates of waste treated by landfill and ocean dumping have been decreasing. In particular, the reduction of waste discharged into the sea indicates that the ocean dumping of sewage sludge, food waste leachates, and livestock wastewater was banned in 2012-2013 as the 1996 protocol to the London Convention7) took effect, and the treatment methods for these types of waste are being changed to incineration or recycling.
7) London Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (1972)

When considering the trend of residential waste treatment between 1999 and 2012, seen in <Figure 7-7>, the percentage of waste that is landfilled has steadily decreased, whereas the percentages of waste incinerated or recycled have increased. These results show that waste treatment measures are shifting from a simple landfill-based treatment to a resource circulation type, creating a virtuous circle of waste resources on the back of the volume-based waste fee system, promoting recycling and waste-to-energy efforts, etc. Meanwhile, the percentage of recycled waste has been decreasing since 2010, which implies waste that was simply recycled in the past is being converted into energy in accordance with the waste-to-energy policy.

Residential Waste Treatment

Likewise, the percentage of landfilled business waste is generally decreasing, whereas the percentage of recycled business waste is significantly increasing. The percentage of recycling of business waste is very high, at 82.4%. This is because construction waste, which has been almost entirely recycled, makes up a high percentage of the total amount of business waste generated, but the percentages of recycling of general business waste and designated waste are generally increasing.

By type of treatment, as of 2012, 97.3% of construction waste and 76.5% of business waste were recycled, 14.9% of them were landfilled, 6.5% incinerated, and 2.1% discharged into the sea, while 54.4% of designated waste was recycled, 16.4% incinerated, 23.0% landfilled and 6.2% treated by other measures (storage).
