Resource Recycling

Basic Approach

We will achieve 100% recycling of waste and end-of-use vehicles generated by Isuzu Group operations by 2050

Management Structure


Promote Effective Resource Use

Reduced Packaging Materials

To reduce environmental impact across the entire Isuzu Group, we are optimizing logistics throughout the supply chain from packaging and shipping KD parts* to overseas factories. In FY2018, in the ASEAN region, we launched, expanded, and promoted the switch from disposable packaging racks, which were treated as waste at overseas assembly plants, to reusable returnable racks. Furthermore, in FY2020, we developed lightweight returnable racks, achieving a 33% reduction in individual rack weight. Additionally, to increase container fill rates, we also introduced two types of racks of different heights. As of FY2024, the deployment of these racks to major destination countries has been completed.

We are also expanding the use of returnable racks for cabs to achieve resource circulation. Previously, for cabs, we used wooden one-way racks, but starting in October 2021, we switched to iron-made returnable racks. With the adoption of iron-made returnable racks, there is no longer a need for wood disassembly tasks at overseas factories such as removing nails, leading to improved safety.
Furthermore, to exploit the upper space generated when loading completed cabs into containers, we developed returnable racks for parts that fit under the cab racks to improve container fill rates through stacking. By loading large parts, such as axles and other parts that were previously shipped using other containers, onto the returnable parts rack, we have reduced the need for approximately 300 40ft-container units per year, contributing to a reduction in greenhouse gas (GHG) emissions during transportation. Moving forward, we will continue to work toward realizing a sustainable society by promoting returnable solutions, reducing materials and containers, and advancing resource circulation to reduce GHG emissions.

Effective Utilization of Water Resources

Isuzu’s business activities entail the consumption of a large quantity of water in vehicle manufacturing, plant maintenance, effluent treatment and many other situations.
Isuzu endeavors to conserve these finite water resources by, for example, encouraging the reuse of treated wastewater and the water used in processes and efforts to consume less water on a Group-wide basis.

Strengthening Initiatives Towards a Circular Economy

The transition to a sustainable society requires a shift from the linear economic system that emerged from the mass production and mass consumption model to a circular economic system. Isuzu will promote the transition to a circular economic system, which focuses on the efficient and cyclical use of resources at every stage of its business, to maximize added value more than ever before.

Initiatives for Maintenance Leases Utilizing Remanufactured Units

We have begun offering maintenance lease services for the large truck “GIGA type-Re” utilizing the Remanufactured*1 Unit.

This initiative involves reoffering maintenance lease services for reconditioned vehicles (hereafter “remanufactured unit vehicles”) that have been subject to Isuzu's remanufactured technology to restore reusable engines, transmissions, and other components to new-like functionality after short-term, high-performance leasing. To restore functionality, we utilize the advanced genuine maintenance tool "PREISM" to assess the vehicle's condition and detect data on parts that require replacement.

Isuzu is striving for zero GHG emissions across the entire product lifecycle by 2050. Additionally, the Company is promoting activities toward achieving a "circular economy," aiming for 100% recycling of waste and end-of-life vehicles.
Due to their higher number of reusable parts compared with new vehicles, remanufactured unit vehicles enable the effective recycling of resources, reduce CO2 emissions, and contribute to the realization of a carbon-neutral society. When comparing the CO2 emissions generated by the manufacture of one unit of "GIGA type-Re" to the manufacture of a new vehicle, there is an approximate reduction effect of about 76 tons*2.
Furthermore, we ensure the same durability and reliability in our remanufactured unit vehicles as in our new vehicles, providing equivalent value and supporting safe vehicle operations for our customers.
Isuzu will continue its efforts to support "transportation” through the provision of environmentally friendly vehicles and to minimize the impact of transportation on the global environment.

Promoting Rebuilding

The Isuzu Group promotes the rebuilding of used engines and parts to more effectively use the limited resources that we have. In the rebuilding of engines, used engines are disassembled, the parts are cleaned and inspected and worn parts are replaced with new ones before reassembly. The Isuzu Group provides customers with genuine Isuzu E-PARTS that have been refurbished to meet the same inspection criteria that new parts straight off the production line must meet. This enables our customers to use products that are more eco-friendly but are of the same high quality as new products. Isuzu Engine Manufacturing Hokkaido Co., Ltd. rebuilds engines and parts to reduce resource input and manufacturing energy. We will further reduce resource and energy input by establishing evaluation standards for parts recycling technologies and recycled parts, improving the parts recycling rate, and promoting and expanding rebuilding.

Promoting Recycling

The Isuzu Group promotes the recycling of the waste generated by its business operations through meticulous sorting on a daily basis and pursues activities to reduce and mitigate the generation of discharge, including by sorting out valuables from the discharge.
Domestically, we also recycle used-cars pursuant to Japan’s Act on Recycling, etc. of End-of-Life Vehicles, as well as three designated items (ASR*, air bags, and chlorofluorocarbon).
Additionally, to recycle and properly dispose of ASR, we have created the Automobile Shredder Residue Recycling Promotion Team (ART), which works in cooperation with 12 other automobile manufacturers.
