Shiga Plant Certified as Super Green Heart Factory

In all of us, a green heart

In November 2011, the Shiga 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)
(Shiga Plant EnMS Project)

ISO 50001

In March 2014 the Shiga Plant obtained certification for the ISO 50001 international standard for energy management systems.

ISO 50001 confirms that a company is carrying out the PDCA cycle towards continuous improvement of energy management. In fiscal 2013, the Shiga Plant launched its energy management system (EnMS) project in order to take part in the model project for strengthening business competitiveness*, an initiative of Japan’s Ministry of Economy, Trade and Industry (METI). Besides aiming for ISO 50001 certification, through the EnMS project the Shiga 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.

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.

* Model project for strengthening business competitiveness (Full name: Model project for strengthening business competitiveness through the planning and implementation of new management systems for business continuity, etc.): METI provides subsidies to companies that are striving to achieve certification for new ISO standards (related to, for example, energy and BCP) so that they can boost their business. There are 28 groups across Japan that have been adopted into this project, and Daikin has been chosen for one of these.

Improving Line Productivity

Improving Line Productivity With a goal of reducing CO2 emissions per sales by 30% over fiscal 2000, we are striving to raise productivity and reduce energy consumption during room air conditioner production.

Developing Innovative Equipment

Developing Innovative EquipmentOn the production lines, employees built a transport and separation device for parts that uses the force of gravity and thus requires no electricity.

Coating Effectively Reflects Sun

Coating Effectively Reflects SunThe Shiga Plant put Daikin's ZEFFLE infrared reflective coating on the roof, resulting in lower temperatures inside the building and less of an air conditioning burden.

Installing LED Lighting

Installing LED LightingConventional lighting in the offices and the plant is being replaced with highly energy efficient LED lighting in order to reduce electricity consumption.

Energy Saving Patrol

Energy Saving PatrolThe factory workers take turns doing regular patrols of their work place in order to find even the slightest waste of energy.

Green Curtain

Green CurtainEach department has planted bitter melons along the cafeteria windows. This curtain has been shown to reduce the room temperature by 6°C and save on air conditioning.

Waste Reduction

Achieved Zero Waste Emissions

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

Thorough Separation and Recycling of Waste

Thorough Separation and Recycling of WasteAll unnecessary items are separated for recycling. And each workplace weighs the items and thinks of ways to prevent these waste items from being generated in the first place.

Reusing Protective Gear
 

Reusing Protective GearInstead of discarding items used by line workers, such as wiping cloths and protective gloves, when possible the Shiga Plant cleans these to be used again.

Waste Material Press
 

Waste Material PressItems such as cushioning material for packaging and plastic bags are placed in a press to remove the air and compact them so that they can be shipped more efficiently to the recycling plant. This also contributes to the stable recycling of materials.

Reusing Wooden Palettes

Reusing Wooden Palettes Logistics companies help us in reusing the wooden palettes used during international procurement. Palettes that cannot be reused are carbonized into charcoal that is used to deodorize the inside of the factory buildings.

Collecting Plastic Bottle Caps

Collecting Plastic Bottle CapsPlastic bottle caps are collected in special recycle bins. This is part of the Shiga Plant's participation in an initiative that recycles the caps to raise money for vaccination of children around the world.

Preventing Air and Water Pollution

Exhaust Gas Treatment Equipment

Exhaust Gas Treatment EquipmentTreatment equipment was installed to purify the exhaust gas from the coating drying furnace. Its filter, which absorbs harmful substances, is activated charcoal made by carbonizing the wood from palettes remaining from logistics.

Water Treatment Facilities

Water Treatment Facilities All wastewater in the plant is channeled to a single location for purification. Daikin has stipulated an in-house standard value for plant wastewater that is stricter than legal limits. The plant works daily to ensure measurements for items such as COD and pH do not exceed in-house standard values.

Pond Functions as Dyke

Pond Functions as DykeA pond that provides a relaxing place for employees to take breaks also acts as a reservoir for all rainwater flowing from the Shiga Plant. If there is an oil spill in the plant, a measuring device at the pond gate sounds an alarm to warn employees in charge. To keep polluted water from flowing into public waterways, there is an emergency gate that can be closed at the pond's outlet. The plant thus has secondary and tertiary prevention measures.

Preparing for Emergencies

Stockpiling Emergency Materials and Equipment

Stockpiling Emergency Materials and EquipmentIn case of emergencies such as earthquakes, fires, or oil spills, the Shiga Plant has emergency materials and equipment stored and ready for use.

Water Quality Monitoring Equipment
 

Water Quality Monitoring Equipment The quality of water in wastewater drains is constantly monitored using special equipment. Any irregularity detected sets off an alarm, and the staff in charge will rush to the scene to fix the problem.

Emergency Water Blockage Gate
 

Emergency Water Blockage GateAn emergency gate at the pond's outlet is closed in case of a problem with plant wastewater. This prevents the wastewater from flowing into public waterways and thus keeps damage to a minimum.

Oil Fence Operation Drills

Oil Fence Operation DrillsTo be prepared in case oil gets into the plant's wastewater drains, drills are held in setting up an oil absorption mat in the pond.

Emergency Drills for the Kitchen

Emergency Drills for the KitchenOnce a year, the Shiga Plant and the kitchen outsource staff hold drills to be ready for any emergency that occurs during meal preparation.

Emergency Drills for Oil Leaks

Emergency Drills for Oil LeaksOnce a year, the plant prepares for leaks of oil or other substances on the road with drills in which soil and oil absorption mats are used to prevent these substances from getting into the street gutters.

Joint Emergency Drills

Joint Emergency DrillsOnce a year, the Shiga Plant joins regional environmental protection associations and government organs in drills that prepare for possible environmental emergencies.

Joint Fire Drills

Joint Fire DrillsThe plant joins in annual fire drills held by the Shiga Prefectural government in which participants practice measures to take in unison with neighboring companies and government organs in case of disasters such as earthquake or fire.

Emergency Drills for Runoff into Rivers

Emergency Drills for Runoff into Rivers Once a year, drills are held with local government organs to prepare to deal with runoff of oil and other substances into rivers.
