In fiscal 2011, the Eisai Group in Japan launched a new plan to
continue to gradually reduce the amount of waste generated,
increase the amount of recycled waste and decrease the
amount of waste sent to landfill while also maintaining zero
emissions. Every year, numerical targets are set for each
operational site and Group company, and efforts are made to
reduce waste.
In fiscal 2012, the total amount of waste generated by the
Eisai Group in Japan amounted to 6,289 tons, a significant
decline of 14.4% compared with fiscal 2011. This decrease
was due mainly to marked declines in the amounts of waste
acid, waste alkali and waste oil accompanying a decrease in
production of pharmaceutical products. Also, the amount of
waste sent to landfill decreased for the first time in three years,
declining 42% from fiscal 2011 to 19 tons. The ratio of waste
sent to landfill to total waste was 0.30%, a 0.14 % decrease
compared with fiscal 2011, meaning that we achieved zero
emissions for the fifth consecutive year. Meanwhile, the
recycling rate was 36.1%, a 1.5 % increase from fiscal 2011,
which reaffirms the progress of activities based on the Waste
Reduction Plan. Going forward, we will continue to promote
waste reduction activities toward the establishment of a
recycling-oriented society.
The Eisai Group in Japan has been conducting intensive
onsite inspections of its waste disposal contractors for the
purpose of checking that waste is being disposed of properly.
For potential new contractors, rigorous onsite inspections are
conducted under the supervision of Eisai Co., Ltd.’s General
Affairs and Environmental & Safety Affairs Department. New
contracts with Eisai Co., Ltd. are only signed after deliberation
by and approval of the Company-Wide Environment and
Safety Committee. Contracts for waste disposal are mostly
given to those companies that have received certification as an
excellent industrial waste processing company.
We make regular onsite inspections of our waste disposal
contractors to confirm that waste is being disposed of properly.
Inspections are carried out once a year for contractors
engaged in the collection, transport and intermediate
processing of waste and once every three years for contractors
handling the final treatment. During fiscal 2012, over 100 on-
site inspections were conducted by the Eisai Group in Japan
at sites around the country, and it was confirmed that waste is
being disposed of in an appropriate manner.
In order to reduce waste, it is essential to reduce the amount
of waste generated in addition to reusing resources such as
metal, glass, waste oil and paper products and recovering
resources from waste. Based on this perspective, we actively
promote the sale of equipment and devices to be reused as
well as the recycling of scrap metal, glass bottles and waste
oil. To reduce waste paper, we are devising better ways to
distribute materials for meetings and to copy documents to
reduce the amount of waste generated, while also promoting
the sale of wastepaper. In fiscal 2012, the amount of copy
paper used by Eisai Co., Ltd. decreased 6.9% from fiscal
2011. Furthermore, we also reuse organic solvents, such as
those used in the chemical synthesis of active pharmaceutical
ingredients, and sell these as auxiliary fuel.
In fiscal 2012, the Misato Plant further segmentalized
its sorting method for waste plastics produced in the
manufacturing process and promoted the recycling of these
back into reusable raw materials. The Misato Plant’s ratio of
recycling waste back into reusable raw materials was 41%
in fiscal 2012, up from 20% in fiscal 2010. Meanwhile, the
Tsukuba Research Laboratories progressed with the use of
environmentally conscious products that included switching
to 100% recyclable resin treatment containers for infectious
waste. Our “contributions to reducing the amount of waste
emissions and promoting recycling” through initiatives
implemented in recent years were highly acclaimed and in
recognition of these contributions, Eisai Co., Ltd. Head Office
was presented with a certificate of appreciation by Bunkyo City
in Tokyo.

Chemical substances that are used in the research and
development and production of pharmaceutical products include
some substances subject to the PRTR System that could have
an impact on the environment. The amounts of these substances
handled, released into the environment and transferred as waste
need to be understood and properly managed. Therefore, in
addition to using our unique reagent management system to
monitor the usage of reagents by the Eisai Group in Japan,
we are also striving to reduce our usage of PRTR designated
substances and to control their release into the environment.
The amount of chemical substances used depends largely on
the volume of pharmaceutical products produced. To maintain
the quality of active pharmaceutical ingredients, it is not easy to
change manufacturing conditions after entering the commercial
production phase. Therefore, we actively reduce the amount of
substances used and utilize alternative solvents from the R&D
stage. The total amount of PRTR designated substances handled
by the Eisai Group in Japan during fiscal 2012 decreased 36%
from fiscal 2011 to 566 tons. This was mainly due to a significant
decrease of 47% in the usage of dichloromethane from fiscal
2011. The total amounts handled during the year of toluene
Groundwater is a valuable source of fresh water. Once
groundwater becomes contaminated, however, it is difficult
to restore this resource to its original condition and identifying
the source of and removing the contamination is not an easy
task. With the aim of preventing groundwater contamination,
the Water Quality Pollution Control Act was amended and
the revised act enforced on June 1, 2012. To ensure that
operational sites possessing research facilities and production
and storage facilities are firmly responding to the revised law,
the Eisai Group in Japan is proceeding quickly with checks
and investigations of facilities and equipments. We are steadily
progressing with strict compliance with standards concerning
structures and with the establishment of usage and inspection
methods.

Response to the Water Pollution Control Act
Proper Management of PCB Waste
and isophytol, which are used in the manufacture of vitamin
E, decreased 17% and 27%, respectively, from fiscal 2011.
During fiscal 2012, notifications were made to authorities for 13
substances, one more substance (formaldehyde) than in fiscal
2011.
The Eisai Group in Japan recovers dichloromethane and
toluene for recycling use or sale and tries to keep any release of
these solvents into the atmosphere to a minimum. Furthermore,
we also promote the use of alternative substances to hexane.
Going forward, we will continue to strive to reduce environmental
risks.
We have quickly completed registrations for polychlorinated
biphenyl (PCB) waste with the Japan Environmental Safety
Corporation and are subsequently progressing with detoxification
processing. In fiscal 2012, Eisai Co., Ltd.’s Head Office treated six
high-concentration capacitors. As a result, we have completed the
treatment of high-concentration PCB waste at the Head Office.
A breakdown of the remaining PCB waste within Eisai Co., Ltd.
is as follows: This waste exists at the Kawashima Plant, Honjo
Facility, Head Office and sales offices, and we give notification
without delay to the relevant prefecture
based on the Law Concerning Special
Measures Against PCB Waste. We store
PCB waste under proper management
that includes installing locks, enclosures
and signs around storage areas as well as
taking measures to prevent vaporization,
scattering or effluence.

With many of its
operations requiring the
handling of chemicals,
Eisai Knowledge Centre,
India deploys scrubbers
during work processes
and minimizes the
dissipation of acidic
gasses and organic
solvents. Additionally, it has established a system for the closed-
system transportation of volatile organic solvents or compounds
containing these solvents. The Centre has also introduced
a system for the surveillance of volatile organic compounds
(VOC) contained in air currents within its plant and focuses on
air pollution prevention in concert with regularly scheduled air
inspections.
Waste generated from processes and laboratories is placed
in various types of waste containers and stored in specialized
locations. Plant wastewater is sorted into wastewater with high
concentrations of dissolved matter and wastewater with low
concentrations, and the treatment of both types of wastewater
is commissioned to respective outside wastewater treatment
plants.
Furthermore, Eisai Knowledge Centre, India promotes
tree-planting activities to raise the environmental awareness
of employees. Tree planting also includes the participation
of students from nearby neighborhoods and visitors to the
plant. To date, 175 mango trees, 31 night jasmine (
Cestrum
nocturnum
) trees and 136 other trees have been planted.
In fiscal 2012, Eisai Knowledge Centre, India was selected
from more than 100 South Indian companies to receive first
place in two categories at the Environment, Health & Safety
(EHS) Excellence Awards 2012 from the Confederation of Indian
Industry based on the high acclaim for its proactive initiatives in
areas related to the environment, health and safety.
Raising the Waste Recycling Rate through a
“Single Stream Recycling” System
Andover Research Institute (U.S.)
Actively Undertaking Environmental Protection
Activities as a Global Production Site
Eisai Knowledge Centre, India (India)
The Andover Research Institute engages mainly in R&D
activities under Eisai Product Creation Systems (EPCS). It
also handles naturally derived substances and operates a
pilot plant that supplies clinical compounds.
Eisai Knowledge Centre, India is a production site for
providing stable supplies of high-quality pharmaceutical
products that patients can purchase at easily affordable
prices. This site proactively works to reduce the
environmental impact associated with its business
activities and three years after its establishment, in March
2012, obtained ISO 14001 certification.
The Environmental Health and Safety Department is
responsible for assuring the safety of all employees at their
workplaces, reducing the environmental impact associated
with business activities and complying with laws concerning
health, safety and the environment. The department consists of
the Safety Committee, Green Team and the Operations Team
and executes its duties concerning health and safety as well as
environmental conservation.
Over the years, the department has promoted initiatives
for energy saving and waste reduction. As energy-saving
measures, it introduced a variable air volume system for drafts
and air conditioning and is also conserving electricity for
lighting and reducing energy consumption during non-business
hours. Since fiscal 2008, it has reduced the amounts of natural
gas and electricity usage by 20% and 6%, respectively, and
over a five-year period following the base year of fiscal 2007, it
has reduced CO
2
emissions by a total of 9,200 tons.
Although the volume of waste generated in fiscal 2012 rose
6% over the amount of fiscal 2011, the recycling rate was
26%, an increase of 11% over fiscal 2011. The increase in the
recycling rate was due mainly to the introduction in fiscal 2011
of a “Single Stream Recycling” system that has expanded
the scope of items that can be recycled. Of particular note,
50% of waste derived from research laboratories, which was
previously incinerated, can now be recycled. Additionally, the
Andover Research Institute is increasing the functions of its air
discharge monitoring system to reduce the discharge of VOC
from the pilot plant.
