Substances listed are those
amounting to at least 1 ton per year. " - "
indicates no entry.
|
|
1. |
Pursuant to the PRTR Law |
|
2. |
The amount of metallic compounds
is converted into metal. |
|
3. |
The environmental impact
coefficient is set by Ricoh, taking toxicity, carcinogenicity,
and the possibility of ozone depletion into consideration. |
|
4. |
Amount treated into non-PRTR
substances, i.e. thermal decomposition, catalic decomposition,
etc.
|
|
The amount of
Ricoh Group's target substances for reduction used and
discharged is calculated using the following formula.
Amount used = {(amount - amount consumed) X
environmental impact coefficient}
| Amount
discharged = |
{(amount emitted
into air + amount discharged into public water supply
+ amount discharged into soil) X environmental impact
coefficient} |
|
|
| * |
Ricoh Group's target substances
for reduction are defined as the PRTR substances designated
by four Electric/Electronic Industrial Associations
in Japan between fiscal 1998 and fiscal 2000. Coverage
chemical substances by Ricoh may differ slightly from
those provided by the PRTR Law. |
