In the 21st century, it has become necessary to give more consideration to the global environment.
These are not matters in which a company can take shortcuts, and Hoya is strongly aware of the need
to make these important management issues a top priority. This consciousness led Hoya to establish
pollution-control committees at each of its factories in 1976. The Company has been continuously
involved in environmental protection activities since that time. During the fiscal year under review, we
implemented environmental accounting at all of our domestic locations, in accordance with Ministry of
the Environment guidelines.
Specific Efforts
(A) Reducing Influence on Environment
There are four areas in which Hoya is striving to reduce its environmental influence per unit of net
sales: energy consumption, water usage, waste volume, and volume of packaging materials.
1. Energy Consumption
The Company has implemented a thorough energy conservation program. At the facilities level, Hoya is
ensuring that all buildings are properly insulated, and is converting all pumps and clean room air-condi-
tioning motors to highly efficient inverter-type equipment. At the human-environment level, tempera-
ture control and efficient lighting systems are saving energy. Converting energy to its equivalent in crude
oil, the Company saved approximately 6,000 kiloliters as compared with the previous fiscal year, but
the ratio of energy consumption to net sales rose by about 3%.
2. Water Usage
Increased water recycling at the Company’s factories helped lower the ratio of water usage to net sales
by approximately 2% from the previous fiscal year.
3. Waste Volume
As a result of the recycling of concrete sludge, the thermal recycling of waste plastic, the reuse of organ-
ic solvents, and the installation of wet-garbage treatment equipment at two plants, the ratio of waste
volume to net sales fell by about 26% from the previous fiscal year.
4. Volume of Packaging Materials
Styrene foam has been replaced by polyethylene terephthalate (PET) as packing material for special-
order lenses. All of our retail stores recycle or reuse packing materials through our Green Network
Communications, and all cardboard boxes used to package our products are reusable. Through these
measures, the ratio of the volume of packaging materials to net sales significantly declined from the pre-
vious fiscal year.
(B) Implementing an Environmental Management System (ISO 14001 Certification)
Hoya submitted its Environmental Management System for ISO 14001 certification in October 1996. In
the fiscal year ended March 31, 2002, two more sites were certified, bringing the Company’s total num-
ber of certified sites to 29.
