Current state and trend of waste and recycling in Japan

T
his report statistically introduces current state and
recent trend regarding resource circulation, industrial
and municipal wastes and recycling of Japan. In Japan, the
ratio of the total amount of recirculated resources to the
national resource input is 15.8% in FY 2014. This ratio has
been increasing continuously over the past 20 years mainly
due to steady progress in the industrial waste recycling and
to gradual shrunk of the domestic natural resource input.
Of the total 255Mt of domestic recirculated resources, 55%
is the amount of resources recycled from industrial and
municipal wastes. The remaining 45% covers used paper,
ferrous/non-ferrous scrap, steel making slag, black liquor
etc. which are not classified as waste. Japanese total waste
volume in FY 2014 is 437 Mt, accounting for 90.4% for
industrial waste and 9.6% for municipal waste. The amount
of resources regenerated from these wastes is equivalent
to 50% of the total waste volume. The final landfill amount
to all waste is only 3.4%. The Japanese Home Appliances
Recycling Act imposes recycling obligation on manufacturers
and distributors of four types of used household appliances
(air-conditioners, TVs, refrigerators, washing-machines).
In FY 2015, totally 11,000,000 units were recycled by the
manufacturers. However, this number is considered to be
only half of the actual used appliances, and the other half
may go to some illegal pass route. The recycling rates by
legal procedure of manufacturers were all very high, 93%
of air-conditioners, 89% of LCD TVs, 82% of refrigerators,
and 90% of washing-machines. In order to expand recycling
to all other small household appliances, the Small Home
Appliances Recycling Act was enforced in 2013. The main
focus is to promote recovery of precious/rare metals. These
small appliances are collected by municipalities and handed
to recyclers certified by the government. In FY 2015, the
recyclers gathered 67kt nationwide, which was only about
1/10 of the final expected amount.
Speaker Biography
Takashi Amemiya received M.S. degree and Ph.D. degree from the University of Tokyo.
In 1978, he joined Toshiba Corporation where he engaged in for 30 years in research
and development work such as fuel cell systems, material and/or energy recycling
systems for industrial wastes and E-wastes. In 2013, He was appointed as a professor at
Nippon Institute of Technology, Japan, and is doing research achievements in the field
of material and resource circulation engineering for the application in environmental
area.
