1 IntroductionThe human being has consumed a large amount of resource and energy and has exhausted a
large amount of environmental load material without considering limit of the earth, under asocial system of mass production, mass consumption, and mass disposal. However, it is
required conversion to a new production/ consumption system and a social economic system
for establishment of sustainable society as today's various global environmental concerns and
the waste problems become serious.
The Sound Material-Cycle Society is a concept for the ne! social system"
#n narro! sense$ it is a society !hich does not discharge !aste into the
society %y recycling" &ur pro%lems are not only !aste pro%lem %ut also
resource pro%lem" &n the other hand$ the Sound Material-Cycle Society is
achieved %y improving the productivity of the resource and energy 'ratio
of production and consumption to input of resource and energy( %y the
saving and recycling the resource in the !ide sense" E)ective use of the
resource and discharge control of !aste is important" Please do not
misunderstand The Sound Material-Cycle Society as *+ar%age , society"*
2 Waste discharge and treatment in Japanased on .aste Management And Pu%lic Cleansing /a!$ 0apanese !aste is
divided into t!o 1inds$ *#ndustrial !aste* of the gar%age !hich goes out of
the factory and *Municipal !aste* !hich is the household ru%%ish" /ocal
governments have responsi%ility for municipal !aste treatment and each
company has responsi%ility for industrial !aste treatment" #n some region$
the municipal !aste includes not only !aste from house %ut also !aste
from o2ce and restaurant"

1) Municipal waste
The amount of the municipal !aste is 34$5,,$,,, tons in 4,,5 6scal
year$ and the !aste amount each day a person %ecomes 5"51g" The localgovernment 'city level( collects gar%age$ and the Ministry of
Environmental Protection totals the data that the each local government
collected in data concerning gar%age"
The ma7ority of the household ru%%ish is ra! gar%age 'left-over food$
scraps from coo1ing and out of use-%y date food( and paper or plastic
used as container or !rapping material$ so measures against this
gar%age are re8uested"

collection and the intermediate processing is 3$95,$,,, tons$ and
amount of the group collection$ !hich is collected %y the resident group

of the land 6ll is 5@9$>5,$,,,m > and the remainder years are 55"4 years"
This is a value !hich increases for :"=; increase and 5": years in theremaining capacity compared !ith the previous year" The remaining
capacity of the 6nal disposal is %eing improved from the rise of
consideration to the !aste pro%lem in recent years" o!ever$ the
reduction in the amount of the 6nal disposal is re8uested strongly
%ecause it is di2cult to construct a ne! disposal place %y the citiBen
protest"
2) Industrial wasteAs for industrial !aste$ %ecause each enterprise is disposing and
treating$ the detail situation is incomprehensi%le" /ocal governments do
the 8uestionnaire survey etc" to each entrepreneur$ Ministry of The
Environmental totals it$ and the situation of industrial !aste is clari6ed
for that"
The amount of a total e haust of industrial !aste in 0apan is a%out
9,,$,,,$,,, tons in 4,,5 6scal year$ and this is a%out eight times the
municipal !aste" #n %rea1do!n of the industrial !aste$ a%out :, percent

in the amount of the 6nal disposal is re8uested as municipal !aste is"
3 Concept of the Sound Material-Cycle SocietyThere are two sides in the purpose of the The ecycling!based" society. #ne is an
environmental load decrease, and another is effective use for the resource and energy. $s for
current environmental measures, the principal ob%ect was put on the &nd of ipe
Technology", which processed the environmental load material exhausted from the man
activity for the environmental load decrease. However, we cannot deal with new
environmental load material (for instance, dioxin and endocrine disrupters) discovered one
after another and a large amount of exhausted wastes only by the &nd of ipe Technology".
The mechanism that measures not only on the exit side but also on the entrance side, in a
word, measures which do not put out the environmental load is necessary. $s for usage of
resource and energy, fossil fuel and the mineral wealth should not be collected one way but
resource circulation and effective use of waste heat should be accomplished.
These environmental load decreases and e)ective use for the resource
and energy are not independent %ut implications" The consumption of the virgin resource is saved at the same time as the environmental load s
decreasing %y recycling of !aste" Moreover$ the resource and the energy
input to !aste treatment decrease %y developing a ne! productive
process !ith a lo! e haust of !aste" #n a !ord$ to achieve the Sound
Material-Cycle Society society is to esta%lish society of high resource
and energy productivity and a lo! environmental load types maintaining
the system !hich o)ers various functions to %e necessary in the social
life$ and this is the same as the construction of the sustaina%le society"

Material recycle$ Chemical recycle and Thermal recycle"
Material recycle
+enerally the recycle is the material recycle !aste$ the material isrecycled in case of conversion !aste to resource again"
Chemical recycle
Chemical recycle is to recycle !aste as a ra! material of chemical
industry$ and it is a 1ind of the material recycle ?or instance$ ma1ing
the PET %ottle oil$ and o%taining monomer !hich is the ra! material
correspond"
Thermal recycle
Thermal recycle is to incinerate !aste and collect heat" #t can %e said toconvert that !aste !hich is unused resources cannot %e used t!ice
'incineration ash($ and the last means of recycle" o!ever$ it is in
!aste !hen energy hangs greatly recycling 'Energy hangs apart as

3)Waste recycle in Japan
ate of recycle in 0apan is 53; in the municipal !aste and 9@; in
industrial !aste" Though they are not high 6gures$ some !astes are
recycled at a high rate in the inside
ecycled material
The material recycled at a high rate is an old paper$ steel can$ an
aluminum can$ and PET %ottle no!" ecause the old paper$ the steel can$
and the aluminum can are recycled easily$ the recycling rate is also high"
&n the other hand$ %ecause the approach on recycle 7ust started$ the PET

Cement is made %y %a1ing mi ed materials that the lime stone$ clay$ and
the iron dice %y 7ust proportions" ecause the element 'calcium$
aluminum$ silicon$ and iron( included in the ra! material of cement isincluded in the incineration ash$ cement can %e made from the
incineration ash" ' o!ever$ it is necessary to remove heavy metals and
chlorines from the incineration ash %eforehand"( Therefore$ the cement
industry is very po!erful as the receiver of the !aste incineration ash"
Moreover$ dio in is decomposed almost completely though dio in might
%e included in the incineration ash %ecause it %a1es it at the high
temperature '5>3, or more( !hen cement is made"
Steel industry
The process of removing iron o ide in the iron ore 'reduction( is done
!ith the %last furnace in the steel industry$ and the !aste plastic is used
as a reducing agent at this time" This method is called a %last furnace
reduction method" #n the %last furnace$ co1e is turned on !ith the iron
ore$ co1e gasi6es$ and the car%on mono ide is discharged" This car%on
mono ide reacts chemically !ith the iron ore$ and the o ygen of iron
o ide is removed" ecause the !aste plastic is the same car%on material
as co1e$ the iron ore is reduced %y %lo!ing in to the %last furnace after
used plastic is crushing and granulation processed as !ell as co1e"
#n 0apan$ there are t!o steel companies !hich have !aste plastic recycle
technology" &ne is 0?E holdings #nc"$ another is Hippon Steel Corporation"
The Hippon Steel has a technology !hich recycles !aste plastic as not
only reductant for a %last furnace %ut also fuel gas and li8uid" &n the
other hand$ though 0?E recycles !aste plastic as reductant$ it is
developing technology !hich recycles !aste plastic including polyvinyl
chloride'PIC(" PIC has %ad impact on the %last furnace$ so %efore !aste
plastic is input$ it re8uires to remove PIC from !aste plastic" 0?EJs ne!

Though the introduction of recycle is !orthy in the point to decrease the

Energy turned on to recycling
Energy is necessary for recycle" There is a possi%ility that theenvironmental load increases !hen energy necessary for recycle
produces %y using the virgin ra! material if it is large" #t is necessary
to avoid putting huge energy to construct the ecycling-%ased
society"
?irst of all$ it is necessary to ma1e the reduction give priority 6rst of
all !hen thin1ing a%out the priority level of a%ove-mentioned > "
ecause$ reduction discharges fe!er environmental loads than reuseand recycle does" He t is reuse$ and 6nal is recycle" ?irst several
measures %esides recycle should %e considered" After that$ if the
necessity of recycle still is e isted such as to icity pro%lem$ the
impact given to the society and the 6nal disposal dump and !astes$ it
is necessary to thin1 a%out recycle"
Demand for recycled goods
ecently$ the 1itchen !aste !hich goes out of the home in various
places is %eing performed to the recycled approach %y an organic
fertiliBer" o!ever$ if there is no receiver of the organic fertiliBer$
organic fertiliBers accumulate in the society and recycling is not
promoted" The old paper has occurred to a similar situation"
Moreover$ the discretion collection of the PET %ottle gro!s more than
the amounts in the processing facilities the amount of the PET %ottle
collection !hich can %e the acceptances though it started in recent
years$ and there is a region !here the receipt !ith the processing

su%sidy$ ta $ license and so on"
At %eginning stage$ huge su%sidy from national government is entered to
the eco-to!n" The national government stops su%sidy soon$ then local
government must continue to pay su%sidy as !aste treatment cost" ?acility
in Eco-to!n often introduces more novel technology than traditional !aste
treatment facility such as com%ustion facility$ so cost to the eco-to!n
facility is very high" ?or e ample$ some city introduced D? facility as a
core technology of eco-to!n" ut D? technology often does not !or1$
%ecause it is not mature technology" So local government pays more
money for treatment cost compared !ith traditional com%ustion facility" To
avoid this 1ind of situation$ each facility in eco to!n should %e
independence from su%sidy of government" .hen each facility gets pro6t$

Bero emission of the factory !as achieved" The reason !hy the %eer

achievement of the Bero emission is severer than this attestation for !astemanagement though #S&59,,5"
Some points for corporate ma1ing to the Bero emission are as follo!"Ma1e the %asic environment plan" oard of the enterprise should
positively ta1e leading in this" Ma1ing to the Bero emission is not
persisted in if the %oard does not understand though the person in

energy Lo! are necessary" This contri%utes to not only ma1ing to the
Bero emission %ut also chec1ing e2ciency of the resource and energy

The consideration of the Bero emission must in6ltrate the employee"
Thorough discretion in the site achieves recycling !aste" #t is necessary
