Our Approach

The SUBARU Group considers it very important for manufacturing companies to help realize a society where materials are recycled continuously and the sustainability of business is assured through recycling to maximize resource efficiency.
The SUBARU Group will help create a society that recycles with the goals of efficient resource recycling throughout the product life cycle, maintaining zero landfill at production bases in Japan and abroad, and taking the 3Rs—reduce, reuse, and recycle—to the next level.
SUBARU is also incorporating recyclability into its automobile design process to make effective use of limited resources throughout the automotive life cycle from raw material procurement to disposal.

Achievements and Initiatives

Raw Materials

SUBARU reuses remnant materials and scrap generated during the production of automobiles as well as end-of-life products that have been collected and other reusables as resources for materials, such as iron, aluminum, and plastics, which account for a large proportion of materials used in making an automobile. Through these efforts, we are promoting closed-loop recycling*1 to reduce natural resource consumption and waste generation.

A method by which waste and scrap generated during production along with end-of-life products are recycled as materials for parts of the same quality and then reused to make products of the same kind.

Raw Materials Used in Automobiles in FYE March 2022 Recycling Method
Iron 467,142 tons Delivered to dealers in the form of iron scrap for reuse
Aluminum 25,288 tons Re-melted at plants and reused almost entirely
Plastics 18,732 tons Crushed again at plants and reused partially
Recycling of aluminum chips

Zero Emissions of Waste from Production

Waste emissions in FYE March 2022 decreased by 9,050 tons year on year due to factors including a decrease in automobile production. As waste is also an important resource, we have maintained zero emissions*2 of waste since FYE March 2015 through maximum recovery and recycling and proper treatment of waste generated. As part of its measures to deal with waste plastic, SUBARU has begun exploring waste plastic material recycling, including the reuse in automotive parts and other applications of reject bumpers from the manufacturing process.

A system in which waste and by-products generated in one industry are utilized as resources by other industries, resulting in no waste discharge. This concept was proposed by the United Nations University in 1994.

Reduction of Wrapping Materials on Bumpers for U.S. Market

At Subaru of America, Inc., non-colored bumpers imported from Japan are re-wrapped for protection during transport within the U.S. In FYE March 2021, we launched an initiative to remove the need for re-wrapping in the U.S. by applying high-strength wrapping material with high shape stability before export from Japan. This initiative targets high-demand parts and thereby also promotes transport efficiency. In FYE March 2022, rollout to 60% of all parts was completed. The company will progress with the initiative to contribute to reducing the amount of plastic material used in wrapping.

Promoting Environmentally Friendly Packaging Materials

The company’s Parts Logistics Center is progressing with environmentally friendly initiatives on packaging materials and began exploring a range of measures in FYE March 2022, namely switching from cardboard to paper packaging for improved transport efficiency, use of packaging materials with 10% content of biomass plastic material, and switching from resin to cardboard pallets.


Zero Emissions of Waste from SUBARU Dealers in Japan

Dealers in Japan are committed to the proper management of waste generated from their business activities and to recycling to achieve zero emissions in Japan. In FYE March 2022, these initiatives resulted in the collection of 24,218 used bumpers, 143,311 lead batteries (containing 1,921 tons of lead material), 5,312 kL of oil, and 145,742 tires.
Zero emission initiatives led by dealers, which work most closely with customers, are activities that will contribute more directly to environmental conservation in local communities. The initiatives are expected to help promote proper processing, recycling, and the effective use of resources.

Recycling of Waste Oil

Waste oil generated at SUBARU dealers in Japan during oil changes is recycled as recycled fuel oil through SUBARU’s zero waste emissions scheme. Flower farmers in Yamagata Prefecture grow beautiful poinsettia and cyclamen every year using this recycled fuel oil to heat their greenhouses.

Proper Processing of End-of-life Vehicles Based on Act on Recycling, etc. of End-of-Life Vehicles

Act on Recycling, etc. of End-of-Life Vehicles

Under the Act on Recycling, etc. of End-of-Life Vehicles of Japan, car manufacturers are required to fully recover and properly recycle automotive shredder residue (ASR), airbags, and chlorofluorocarbons (CFCs) from their end-of-life vehicles.
SUBARU has been promoting the smooth, proper, and efficient recycling of ASR by establishing, together with 12 other automakers and other companies, the Automobile shredder residue Recycling Promotion Team (ART).*3 We also ensure proper processing of airbags and CFCs through operations of Japan Auto Recycling Partnership Ltd., established jointly with Japanese automakers and importers.

A team to promote the recycling of ASR, organized by 13 automobile manufacturers in December 2003. The team plans the smooth, proper, and efficient recycling of ASR, a waste product that is classified as one of the Parts Specified for Recycling as defined by the Act on Recycling, etc. of End-of-Life Vehicles and required to be recycled under the law.

Proper Processing of End-of-life Vehicles

SUBARU is participating and collaborating actively in the building of an automotive recycling system to reduce the environmental impact of end-of-life vehicles. SUBARU is also focusing on promoting the development of easy-to-recycle vehicles, and collaborates with its dealers nationwide by jointly operating an automotive recycling system aimed at promoting the proper processing and raising the recycling rate of ASR, airbags, and CFCs.
In FYE March 2022, the ASR recycling rate was 96.6%, achieving the legal target of 70% for FYE March 2016 and thereafter. The airbag recycling rate was 95.4%, exceeding the legal target of 85%, and all CFCs recovered were processed properly.
Detailed information on the level of progress with these recycling initiatives and SUBARU’s other activities based on the Act on Recycling, etc. of End-of-Life Vehicles is disclosed separately on the web page indicated below.
