Overview of Improper Construction Waste Disposal Issues
In 2001, improper disposal of construction waste became an environmental issue in Japan, and the promotion of reuse of construction by-products began to be discussed. The treatment of asbestos-containing materials and the prevention of illegal dumping became issues, and progress was made in legal regulations and corporate technological development. 2010s saw the strengthening of sorted collection and an increase in recycling rates, triggered by the earthquake reconstruction efforts. On the other hand, lack of local treatment facilities and immaturity of mixed waste recycling technology remained challenges. 2020s: With Tokyo generating approximately 4 million tons of waste annually and the recycling rate remaining at 72%, companies introduced AI sorting robots and asbestos detoxification technology. Regulations have been tightened, with fines of up to 100 million yen for violators due to a revised law. Cooperation between the community, companies, and citizens is required for
a sustainable society.
