Waste plastic type

A Rank (Recycled PET bottle)

B Rank(Recycled PET bottle/Waste plastic)

C Rank (Mix plastic)

Applicable for activatedcarbon for electrode material
as almost no materials beside
PET bottle have not been
contained. Specific surface
area is 3,000 to 3,600m2/g,
highest-grade of all ranks.

Other materials than PET areslightly contained. As activatedcarbon, the performance isinferior to A rank products, but
is applicable for air conditioner,
filter of vehicle and deodorant.

Plastic other than PET and resin
are considerably contained.
At present, 80% of such waste
are incinerated or buried in theground at cost. These materials
are applicable for block, wallmaterial and soil improvement.

Materials other than PET:
Approx.5%

Materials other than PET:
Approx.10 to 30%

Materials other than PET:Approx.40 to 80%

Heat island control method withheat exchanger.
We have developed a building material thathas a snow melting function by adding heatdissipation effect due to the thermal
conductivity of carbon.
The mixed carbon is produced from waste,
and this technology also contributes to theeffective use of resources.
