Changes to Aigi Disposal Site
1998
Now
Non-flammable garbage and large-sized garbage was brought in, leading to a mountain of garbage. Landfill volume was 260,000 tons per year.
Due to waste reduction and changes in waste treatment methods, landfill is mostly incinerated ash and slag (covering soil) after melting.
Landfill volume has been reduced to 50,000 tons per year.

Risk for the burden of sorting/disposing becoming too much for households, making it difficult to maintain their support for waste reduction
Ongoing aging of population Increase in single households,
nuclear families Dilution of local community ties Increase in people moving in
from outside the city Increase in foreign population Diversification of information
…and other rapid changes to social conditions and lifestyles
Single Households
This trend will accelerate in the
future
Need to think about forms of cooperation and future burden on citizens when aiming to build a sustainable, recycling-oriented society
Station disposal burden
Sorting burden Local Communities
…Etc. Changes to citizens who supported waste reduction
