SEe Power Source Management Panel Shows How Energy is Used

SEe Management Panel, a sign with the manager's name on, is put up at the facilities during operation. This panel gives a visual representation of the facilities' operation, allowing excess energy to be cut and manufacturing to be carried out using only the amount of energy that is needed.

Innovative Transport

Innovative Transport

This room is rigged so that by placing parts in their set location, they are sent with the proper part trollies without the need to use any electricity.

Installation of Solar Power Panels

Installation of Solar Power Panels

Solar power panels that have been installed on the factory roof generate approximately 20,000 kWh a year. This electricity is used to run the lights in the canteen and to power development of a water heating system in the plant's R&D building.

Using Natural Energy

Using Natural Energy

Employees made wind and water power systems that use the airflow from plant ventilation fans and water level differences. The power generated is used for the parts transport trollies.

LED Outdoor Lighting

LED Outdoor Lighting

The outdoor lighting that guides customers arriving at the factory entrance was converted to LED.

Waste Reduction

Achieved Zero Waste Emissions

Achieved Zero Waste EmissionsAchieved Zero Waste Emissions

In August 2001, the Sakai Plant achieved zero emissions
(recycling ratio of at least 99.5%).

Weighing System

Weighing System

Unnecessary items are divided into 20 categories for recycling. Each workplace weighs the items and thinks of ways to prevent these waste items from being generated in the first place.

Preventing Air and Water Pollution

Atmosphere-Friendly Equipment

Atmosphere-Friendly Equipment

The plant has introduced low NOx boilers that emit fewer pollution-causing nitrogen compounds than conventional boilers.

Continuous Monitoring of Wastewater

Continuous Monitoring of Wastewater

Plant wastewater is concentrated into one location where it is purified. Based on in-house standards stricter than government regulations, the wastewater is monitored 24- a day, every day of the year to ensure that measurement figures for criteria like COD and pH do not exceed standard values.

Preparing for Emergencies

Emergency Shed

Emergency Shed

Emergency materials are stored inside a special shed in case of disasters such as earthquakes, fires and chemical substances leaks.

Drills for Water Quality Emergencies

Drills for Water Quality Emergencies

Drills are held twice a year to prevent chemicals and other substances from flowing into storm drains during natural disasters.

Soundproof Walls

Soundproof Walls

The plant constructs soundproof walls around its perimeter or at high locations, and has voluntary noise standards stricter than noise laws. Windows have been placed in the walls to avoid creating a feeling of being closed in, and trees have been planted for aesthetic purposes.

Greening the Plant

Creating Biotopes

The Sakai Plant has made a biotope so that the premises can provide an environment suitable to life forms native to Sakai City. At the site's sports day, employees and their families planted seedlings as part of grassroots employee efforts to protect and enhance the environment.

The tennis courts at the Kanaoka Factory have a 'green wall' of vegetation.
This wall uses hedera helix, a type of ivy ideal for such green walls.

Exchange with Local Communities

Summer Festival

Every August, a Noryosai Bon dance festival is held to allow plant employees to interact and enjoy with local residents.

Summer Festival

Young employees and local elementary school students take the stage to excite the crowd with 'yosakoi soran', a type of modern festival dance.

Exchanges

Exchanges

Every July, an exchange is held with the neighborhood association. By listening to opinions that the association has about the plant, Daikin strengthens bonds with the local community.

Rugby School

Rugby School

The plant field is open for use by the Sakai Rugby Club three times a month. This contributes to the growth and development of about 130 students in elementary and junior high school.

Factory Tours for Elementary Schools

Factory Tours for Elementary Schools

For more than 20 years, the plant has been helping elementary schools with their open learning classes by inviting grade 5 students from local elementary schools to tour the factory.

Earthquake Simulations

Earthquake Simulations

A special truck with an interior that can simulate an earthquake was at the annual summer Bon Dance to let people experience what an actual earthquake is like. This is one way Daikin contributes to disaster preparation.

Local Cleanup Activities

Local Cleanup Activities

Once a month, all employees take turns picking up litter on streets around the plant. In addition, starting with Daikin's June Environment Month in 2010, we have been holding cleanup activities in nearby children's parks.

Social Contribution

Actively Volunteering in Publicly Sponsored Activities

The Sakai Plant took part in tree-planting in the Forest of Coexistence, a project to create green space in the Rinkai area of Sakai City. It also played an active role in a purse-snatching prevention campaign sponsored by the local crime prevention association by providing bicycle carriage covers and promoting awareness of purse-snatching. (The Sakai Plant received letters of appreciation for both of these efforts.)
