The Sakai Plant has two factories: the Kanaoka Factory and the Rinkai Factory.

Sakai Plant Certified as Super Green Heart Factory

In all of us, a green heart

In November 2011, the Sakai Plant was certified as a Super Green Heart Factory. This was the result of all employees making that all important extra effort and working together to systematically reduce environmental impact while strengthening relations with society.

Super Green Heart Factory:
The system was introduced in fiscal 2006 to certify factories with outstanding environmental performance as Green Heart Factories. Plants that score at least 95 points out of 100 on seven criteria including reduction of environmental impact and relations with the local community are designated as Super Green Heart Factories.

Energy Saving

Certification for Energy Management System (ISO 50001)

In May 2015 the Shiga Plant obtained certification for the ISO 50001 international standard for energy management systems (EnMS).

ISO 50001 confirms that a company is carrying out the PDCA cycle toward continuous improvement of energy management. Besides aiming for ISO 50001 certification, the Sakai Plant ensures that matters such as energy savings and compliance with the Law Concerning the Rational Use of Energy are built into the site’s systems so that its EnMS satisfies the specific needs of the site.

Daikin sites in China, including Daikin Air-conditioning (Suzhou) Co., Ltd. and Zhuhai Gree Daikin Device Co., Ltd., are currently preparing for ISO 50001 certification. The Shiga Plant will make maximum use of this EnMS so that it can become a model plant for affiliates in Japan and other countries and thus contribute to the acceleration of energy-efficiency activities.

SEe Power Source Management Panel Shows How Energy is Used

SEe Power Source Management Panel Shows How Energy is UsedSEe 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 TransportThis 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 PanelsSolar 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 EnergyEmployees 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 LightingThe 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 EmissionsIn August 2001, the Sakai Plant achieved zero emissions (recycling ratio of at least 99.5%).

Weighing System

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

Continuous Monitoring of Wastewater

Continuous Monitoring of WastewaterPlant 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 EmergenciesDrills 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.

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

Summer FestivalEvery August, a Noryosai Bon dance festival is held to allow plant employees to interact and enjoy with local residents. The 2014 event was attended by about 13,500.

 

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

Exchanges

ExchangesEvery 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 SchoolThe 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 SchoolsFor 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 SimulationsA 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 their turn picking up litter on the streets around the plant site. June 2010 was Environmental Month, when employees picked up litter in a nearby playground for children.

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.)
