N-3. Domestic Waste Generated per capita
1.Current Values
1.111 grams / person (Fiscal 2002)
2.Current Points (out of a perfect score of 100 by 2050)
3 points
Calculation method:
(Current value minimum value) / (2050 target
value minimum value) x 100
3. Explanation of Indicator
In a sustainable society, waste product
generation is held to a minimum and resources
are efficiently recycled. Realizing sustainable
recycling of resources of the sort that exists
in nature cant attained by increasing energy
consumption in the form of large-scale production,
large-scale consumption, and large-scale recycling.
It is essential to first limit the generation
[of waste] and to make them biodegradable both
in quality and quantity.
We have chosen per capita total daily trash discharge
as an indicator because changes in individual
lifestyles hold the key to accomplishing these
objectives.
4.Target for 2050
411 grams / person day
5.Ideal for the Future
411 grams / person day
6. Rationale for Ideal and Target Values
An ecological footprint
is expressed in terms of area and is how much
biologically producible land and water are needed
to support human subsistence in a given region.
Currently, the area that the planet can actually
supply is 2.18 hectares (just under 5 acres),
but in Japan it is 2.7 times that, or 5.94 hectares
(about 14.7 acres). This would indicate that the
environmental burden of the Japanese lifestyle
must become 1/3 (more precisely 1/2.7) of what
it currently is. For this report we are hypothetically
applying this figure in our calculations.

Nation-wide general waste (trash and
sewage) total discharge at 51.61 million tons,
assumed to continue unchanged for some years.
