Cogeneration Systems

Solar Power Generation Systems

High-Efficiency Lighting

The Yodogawa Plant has introduced cogeneration systems, which make use of the waste heat generated during power generation. The result has been a 20% reduction in CO₂ emissions.

The plant has installed a waterproof, all-in-one flexible solar power generation system on the roof on a trial basis. The system uses Daikin ETFE fluoropolymer film to improve the solar panels' resistance to weathering and dirt. The system can generate up to 6 kW (enough to power two homes).

Lighting in regularly used rooms like offices and conference rooms was converted to inverter-type fluorescent fixtures, resulting in a decrease in electricity for lighting of about 30%. The plant is also gradually switching outdoor lighting to LED.

Environmental Patrols

The plant's environmental activities include patrols to ensure the facility is operating in accordance with the energy saving management guideline. For example, patrol members check things like temperature settings for space heating and cooling, the energy saving modes of PCs, and the turning off of unnecessary lights. These patrols also make all employees aware of their role in saving energy.

Recovering VOC Solvents

Water Treatment Facilities

Managing In-House Standards for Wastewater Treatment

The plant works to reduce the amount of VOCs, such as the solvents used in the fluoropolymer manufacturing process, released into the atmosphere by recovering at least 70% of them using activated charcoal.

The plant carries out thorough control of the quality of the wastewater discharged by using activated charcoal and other methods to remove at least 99% of the emulsifiers and other substances used in the fluoropolymer manufacturing process.

Daikin has stipulated an in-house standard value that is 25% stricter than legal limits for plant wastewater. The plant works daily to ensure measurements for items such as fluorine and pH do not exceed in-house standard values.

Thorough Separation of Waste

How Materials are Recycled

Unnecessary items from offices and production processes are separated for recycling. The recycling bins are see-through to ensure materials go in their proper place.

Posters with photos of waste items to be separated are placed at separation stations to ensure materials get recycled properly.

Unnecessary items are separated and recycled as, for example, solid fuel, boards, and cement.

Joined the Special Firefighting Team of Settsu City

Stockpiling Emergency Materials and Equipment

Disaster Training

Thirteen employees from the Yodogawa Plant joined the special firefighting team of Settsu City, which is the first of its kind in Japan. These employees have a registered pump truck and make up the Daikin team. Since January 2010, the Daikin team responds to requests for assistance in case of a fire nearby and at the site offers assistance under the guidance of the Settsu City Fire Department.

In preparation for a range of disasters, such as flooding and fires from a major earthquake and tsunami, or chemical leaks, emergency materials and equipment are stored at 22 locations at the Yodogawa Plant. In case of a major disaster, there are stockpiles of water, food, and toiletries so that employees can monitor the chemical plant and ensure safety at the site around the clock.

The plant holds comprehensive disaster training three times a year with participation from the fire department and police department. The plant also takes part in disaster training sponsored by Osaka Prefecture and Settsu City.

Safety Confirmation System Established

A system was established that can confirm the safety of all people on the site including visitors approximately 20 minutes after a disaster occurs, thus ensuring that each and every person is accounted for.

Bon Dance Festival

Kendo Training Hall for Children

Factory Tours for Elementary School Students

Every August, local residents are invited to a Bon dance festival held on the grounds of the Yodogawa Plant. At the 39th edition of this festival in 2010, approximately 22,000 attended.

Daikin employees teach local children kendo in the Yushinkan kendo training hall at the Yodogawa Plant. The training hall celebrated it's 35th anniversary in 2010.

Grade 3 students from two nearby elementary schools were given factory tours in 2010. The children listened and watched with intense curiosity and many later wrote thank-you letters to Daikin.

Cleanups of Local Streets

Cleanups of Local Waterways

Emergency Supply Shed for Local Residents

Division and section managers lead cleanups of local streets twice a month. Participants are often encouraged by words of gratitude from passers-by.

Residents of Daikin's bachelors' dormitory join local residents in cleaning up waterways, part of the Yodogawa Plant's efforts to join in preserving the local environment.

Besides the emergency materials and equipment previously mentioned, the Yodogawa Plant has two sheds on-site containing emergency supplies for local residents to use during a disaster. At annual plant tours for the neighborhood association, Daikin shows how to use these supplies.
