Environmental Initiatives

HIRAOKA also places great importance on environmental initiatives.

Improving a product’s longevity is essential for ecology.

HIRAOKA's products are designed to be durable and to last a long time.
Using a product for long periods effectively increases the value of the resource and reduces the expenditure of energy needed to reuse and recycle.

Improved durability is the best ecology.
For example, even after 15 years of use, the tensile strength retention rate of HIRAOKA's UM-200 retains 80% or more of its standard strength. We are also researching ways to improve the durability of HIRAOKA's regular products including canvas and curing mesh.

We aim to conserve energy by controlling carbon dioxide emissions.

The speed of global warming can be reduced by suppressing the carbon dioxide output. Today, the best course of action for us is to reduce the use of energy we consume on a daily basis. We need to shift to an energy-saving society. According to the Agency for Natural Resources and Energy, in summer, a 1°C increase in the temperature setting of an indoor air conditioner (2.2 kW) (from 27°C to 28°C) for (9 hours/day; daily temperature of 31°C) can save 30.24 kWh electric power and reduce carbon dioxide output by 12.4 kg over the course of a year. If we can reflect the infrared light during the summer season before it enters the room and decrease the internal temperature by 5 to 7°C, the reduced load to the air conditioner will save energy.

HIRAOKA has commercialized COOLMAX, a series of heat shield membrane sheets that decrease their own internal temperatures by up to 5 to 7°C by reflecting the infrared light irradiated from the sun. HIRAOKA also produces a membrane material for tent warehouses called ULTRAMAX COOL and a sheet for membrane called SUNDREAM COOL for structures such as canopies.

In an ongoing effort to reduce the burden on the global environment, we will continue to work actively on resource conservation.

In 2010FY, Japan set the ambitious target of improving resource productivity by approximately 40% versus the 2000FY level. Two methods are available to reach this target.
One is to develop a high added value product with quality and durability necessary to last for many years. Another is to minimize resource inputs through efforts to conserve resources.

Hiraoka has introduced a co-generator in its Soka Factory to progress toward this target and reduce energy costs while minimizing the consumption of organic solvents.
We will actively work to save resources with the aim or reducing the burden on the global environment.
