Environmental Impact Analysis

Environmental Conservation Activities
Environmental Impact Analysis
The Ricoh Group, using the Comet Circle concept1, identifies the overall environmental impact of its products and
business activities to bring about more
effective impact reductions. For this
purpose, the Ricoh Group constructed
an Eco Balance-based environmental
impact information system2 that makes
use of both LCA and Eco Balance
methods. The Ricoh Group adopted
both methods following a long-term
research on LCA, which indicated that
LCA was necessary in conjunction with
Eco Balance if the Group was to
respond to a variety of requests for
clarification on the environmental
impact of its products and business
activities.

The Ricoh Group used an integrated analysis method [See (2) in the figure on the
right] to determine which of its business
activities had the most environmental
impact. It was discovered that upstream
activities and chemical substances contained in products had the highest values.
This means that the manufacturing of materials and parts and the chemical substances contained in products had the
most effect on the environment.
Therefore, the Ricoh Group, according
to its fiscal 2001 medium-term action plan,
will strive to (1) collect its products for
the recycling of materials and parts and
(2) reduce chemical substances, especially
lead, that have the most effect on the
environment.

Ricoh established an LCA research team in
1994 to conduct practical research on LCA
and has released a variety of case study
reports. With more case studies being conducted, such issues as the importance of
explaining the usage of LCA and the difficulties of collecting data and setting
research conditions are being clarified.
● Digital duplicator LCA
(Tohoku Ricoh)*
Making use of the knowledge obtained by
the LCA research team, manufacturing subsidiaries are also conducting LCA.

1. LCA is a means of quantitatively determining the level of
environmental impact generated throughout a product’s life
cycle, from resource procurement to manufacturing, transportation, usage, maintenance, recovery, recycling, and disposal.
Even a partially determined level of impact can be used.

LCA is used to quantitatively identify the
environmental impact made by a product
throughout its life cycle and the influences
a change in design or manufacturing process would have.
More effective environmental conservation activities will be the result of such
assessment. LCA information on copiers
was disclosed on Ricoh’s Web site2 in fiscal
2000.
Ricoh participates in government committees and other gatherings to help improve the LCA method and conduct research
with scholars and company representatives.
