Daikin Circular Economy Initiatives

To cope with resource shortages caused by increasing populations, the circular economy is a concept that aims to generate profits using end-of-life resources and discarded materials involving drastic changes to socio-economics at the level of design and business models to enable a linear system of circulation at various levels from production to disposal.

Daikin is reinforcing its global repair system, product designs that are easily recyclable, product and packaging material resource conservation, as well as the recycling and reduction of waste emitted during production processes, in order to use resources more efficiently.

3R & Repair

Stressing Effective Use of Resources in Design

Daikin Industries, Ltd. strives to use resources as effectively as possible by carrying out the 3Rs—reducing, reusing, and recycling—along with repairing under its 3R & Repair initiative.

This initiative plays a key role in our product design and development. Based on product assessment, we design and develop products that are smaller and lighter, have fewer numbers of parts and screws, and that use materials and construction that make them easy to maintain, separate, and recycle.

3R & Repair: Approach

Reduce Make products smaller and lighter, Use recycled materials
Use of existing product bodies and pipes
Reuse Use parts from end-of-life products
Recycle Development Design products that are easy to separate and recycle
  • Use plastics that are easy to recycle
  • Indicate the materials used
  • Construct products that are easy to disassemble
After use Recycle end-of-life products
Repair Development Design products that are easy to maintain
After sales Have a repair support system that contributes to long-lasting products

Environmentally Conscious Design


Designing Products for Easy Disassembly

Product design stresses 3R & Repair based on product assessment. Since 1997, we have designed products so that their construction makes them easy to disassemble.

In fiscal 2019, we increased the recycling rate by eliminating the painted surface of plastic parts for the Stylish Flow indoor unit of the SkyAir series of air conditioners for shops and small offices.


Making Smaller and Lighter Products that are Still Energy Efficient

Making products smaller and lighter means they will use fewer resources. When making air conditioners, for each product we set weight reduction targets for both the entire product and its components. However, it is technically difficult to achieve this without sacrificing energy efficiency. If making it smaller and lighter means that it consumes more energy, then the product's environmental performance throughout the entire lifecycle has not yet been improved.

When Daikin Industries, Ltd. develops new products, we establish weight reduction targets for each product on the condition that the annual performance factor (APF) does not decrease.

Details of Main Initiatives

  • Reduced the weight of EcoZEAS, a newly released model in April 2020 in the SkyAir series of air conditioners for small offices by 10 to 15% of the conventional model with the adoption of a new swing inverter compressor.
  • Reduced the weight of the water storage unit and heat pump unit of commercial EcoCute by 7% each through weight reduction achieved with the utilization of unit components of residential EcoCute.
  • Reduced the number of outdoor units by maximizing water and heat sources of VRV multi-split type air conditioners for commercial buildings.

Reduced the Weight of Replacement Parts by Upgrading Only the Components and Functions of In-Use Air Conditioners

We offer the retrofit system, a maintenance service that improves air conditioner performance by replacing only the control panel, which serves as the brains of an air conditioner, and the compressor, or the heart of an air conditioner, with new components, for multi-split type air conditioners for commercial buildings in use. By replacing parts with new ones, not only is energy efficiency improved, but replacing only the parts that need it serves to reduce the weight of replacement parts by about one-third compared to replacing the entire air conditioner with a new one.

In fiscal 2019, we expanded the models of air conditioners eligible for the retrofit system. Going forward, we will continue to increase the number of eligible models and strive to conserve the use of resources in products and parts.

Product Packaging Usage Reduced by 3% Over Fiscal 2016

Daikin strives to reduce the usage of packaging for air conditioners from the perspectives of switching from cardboard to styrofoam, thinner designs, and reduction of components and cardboard area.

In fiscal 2019, Daikin Industries, Ltd. achieved its target for reducing packaging usage by 3% compared to fiscal 2016 by significantly reducing packaging usage by switching the transport position of Vente Air total heat exchangers to vertical.

In addition, overseas we increased the number of air conditioners that can be loaded into containers by eliminating corner parts of outdoor units made in Malaysia. This helps to reduce the usage of packaging and mitigates environmental impacts of transport.

Won Multiple Awards at the 2019 Japan Packaging Contest

Improved Packaging of Filters for Removing Electrical Noise

We revamped the packaging design of active filters available as an option to multi-split type air conditioners for commercial buildings, greatly reducing the amount of packaging used. We developed a simple design where the bottom of the product's circuit board is supported with cardboard placed underneath it, and the circuit board's frame is fixed in placing using an intermediate layer. This successfully protects the exposed electrical components on top of the circuit board from touching packaging. This packaging won the top prize in the industrial packaging category at the Japan Packaging Contest 2019 organized by the Japan Packaging Institute and the World Star Award at the 2020 WorldStar Packaging Awards organized by the World Packaging Organisation (WPO).

Use of All Cardboard Packaging for Air Conditioner Repair Parts

We have used wooden frames to enclose parts when exporting air conditioner repair parts to certain regions around the world where returnable packaging could not be used. We successfully developed a fully cardboard packaging solution that maintains the same strength as this wooden frame.
By reducing the use of wood in packaging, we can now utilize wood resources more effectively. Furthermore, reducing the size and weight of packaging also improves transport efficiency and mitigates environmental impacts during transport. This solution received the Japan Star Award (Director-General, Manufacturing Industries Bureau, Ministry of Economy, Trade and Industry Award) at the Japan Packaging Contest 2019 organized by the Japan Packaging Institute.

Repair and Reusing Parts that have Already Been Replaced

At Daikin, we try to use resources efficiently. We take parts that have already been replaced and that contain multiple components, such as printed circuit boards, and we repair any malfunctions or replace the worn-out components. These parts (the printed circuit board, for example) are then tested for quality by ensuring that they are functioning properly and, with the customer's permission, are used as replacement parts when performing repair on a product.


Reinforcing the Global Repair System

Making products that last longer means that fewer resources are used. To this end, Daikin is strengthening its repair system by establishing service outlets around the world to take customer repair requests and questions and enquiries regarding products.

In Japan, the Daikin Contact Center is open 24 hours a day, every day of the year to take inquiries. We will continue to strive for even greater customer satisfaction by improving the technical expertise and etiquette of our service engineers through an engineer certification system. To ensure that customers phoning with repair requests get prompt responses, we have a database of past repair cases, practical know-how, and rules of thumb that Contact Center staff can access immediately. By asking for necessary information and providing appropriate instructions to customers over the phone, we avoid unnecessary service calls, thus improving work efficiency and boosting customer satisfaction.

As Daikin products are sold in an increasing number of countries, we are working to strengthen our service network in each country. By introducing service management systems, we are making workflow more efficient and providing more high-quality and transparent service in every phase of customer interaction including through our service engineers and our partner companies.

Recycling Residential Air Conditioners

Daikin Achieves Recycling Ratio of 90%, Well above Obligations under Home Appliance Recycling Law

Japan's Home Appliance Recycling Law obligates manufacturers to recycle at least 80% of the material from their own residential air conditioners as well as recover and then reuse or destroy refrigerants.

In fiscal 2019, we recovered about 410,000 products totaling 17,197 tons. The recycling ratio was 91% and the amount of fluorocarbons recovered was 530,000 tons-CO2.
