A
mendments to Japan's Act on the Rational Use of Energy required a response from Hoya as a
corporate entity.
Responding to the amended Act was an important component of the Hoya Group environmental
protection initiatives in fiscal 2011. The Company gave a briefing on the Act’s key amendments
to the officers and employees in charge of environmental protection at each division to make the
details widely known. The amendments required Hoya to keep track of the energy the Group
consumed not only at the level of manufacturing bases, but down at the level of individual sales
operations and stores. Most of the energy the Hoya Group consumes is electricity. In preparing
to adapt to the amended Act, the group developed a framework for a detailed account of the
power each facility consumed in fiscal 2010, based on data from electricity bills and other
resources. In fiscal 2011, a system to effectively monitor power consumption was introduced,
and the reports the system generated, stipulated by the amended Act, were duly submitted to
the relevant government ministries and agencies.
Replacement of Transformers at Power Intake Facilities
Transformers at the power intake facility at one of Hoya’s factories in Koka, Shiga Prefecture
were replaced for renewal with the most efficient, state-of-the-art model. This measure had the
impact of reducing power consumption 34,588 kWh per year, equivalent to a reduction in CO2
emission of 12 tons annually. The old transformers were disposed after they were properly
inspected to contain no PCB. These measures were duly recorded in the aforementioned reports
stipulated in the amended Act.
Energy Efficient Lighting Fixtures
The Hoya Group’s factories, buildings and offices have also been re-equipped in stages with
energy efficient lighting fixtures.
A
Hoya Group factory in Nagai City, Yamagata Prefecture, for example, completely re-equipped
with energy efficient lighting fixtures in March 2011 is projected to consume 3.2% less power for
lighting in fiscal 2012.
A
s an additional measure, the factory’s vending machines are scheduled to be replaced with
energy-efficient models.
Replacement of Old and Worn Out Feed Pipes for Chemical Agents in Waste Water
Treatment Facilities
Chemical agents had begun to crystallize inside the aging feeder pipes to a waste water
treatment facility in Hoya’s factory in Koka, Shiga Prefecture. As it was conceivable for the pipes
to clog and affect the treatment of waste water, steps were taken to prevent an environmental
accident beforehand. Together with renovating the water treatment facility, the polyvinyl chloride
feeder pipes were replaced with hard vinyl chloride more resistant to rupturing under impact,
insulated to prevent freezing in the winter and equipped with a dedicated valve for flushing out
clogs.
Recycling Empty Contact Lens Containers
Disposable lenses are the most popular contact lens product at
the Eye City contact lens specialty chain operated by the Eye Care Division. In fiscal 2010, Hoya
