Working towards a Recycling-based Society

As a result of being a mass-production, mass-consumption, and mass-disposal society, we now face many problems such as the depletion of resources and increasing waste. The increase in plastic waste has led to marine plastic pollution in the worldʼs oceans—now a serious problem for society.
The Kubota Group sees working towards a recycling-based society as one of its materiality, and has been advancing initiatives to promote “reduce” (reducing the amount generated), “reuse” (internal recycling and reuse), and “recycle” (improving the recycling ratio) of waste, in addition to initiatives to promote the effective use of resources and resource saving.

Waste, etc. from Business Sites

1. Waste, etc. discharge

In FY2021, the waste discharge amount was 117 kilotons, an increase of 16.6% compared to the previous year. On the other hand, waste discharge per unit of sales improved by 1.7%. The amount of waste discharge decreased in FY2020 due to the impact of the COVID-19 pandemic, but increased in FY2021 as production ramped up at machinery- and casting-related sites while new sites began full-scale operations. Per unit of sales, the rate of waste discharge improved as consolidated net sales increased (up 18.5% from the previous year) while waste volume was curbed by promoting the conversion of used pallets and iron-containing dust into valuable material.
Of the waste discharge amount in FY2021, the amount of hazardous waste discharge was 6.3 kilotons, up 3.7% from the previous year.

  • Trends in Waste, Etc. (including valuable resources) and Waste Discharge per Unit of Sales

  1. *1.To reduce overall emissions to the outside of the Group, including valuable resources, metal scraps generated at machinery production and related sites are collected for recycling at cast iron production sites within the Group. From FY2019, as a way of evaluating the progress of these activities, calculation standards have been changed so that transfer of valuable resources between business sites within the Group is no longer included in the valuable resources figure, but is counted instead as in-house recycling and reuse.
  2. *2.Landfill disposal = Direct landfill disposal + Final landfill disposal following external intermediate treatment

  5. *5.Values for FY2015 and FY2018 were corrected to improve accuracy.

2. Measures to Reduce Waste

The Kubota Group has established the Medium-Term Environmental Conservation Targets and is working to reduce the emissions of waste and hazardous waste and increase the resource recycling ratio at production sites. The Group has been promoting various measures, such as the thorough separation of waste according to the type and disposal method of waste, the introduction of returnable packaging materials, and shared waste recycling between sites. The Group is continuing to promote reductions in the volume of sludge, waste oil, and oily wastewater generated at painting booths, and to reduce the volume of waste plastic emitted from plastic molding processes. Meanwhile, as measures to reduce disposable plastics, we introduced initiatives at certain worksites to withdraw the use of disposable tableware in the employee cafeteria and reduce the issue of plastic shopping bags in on-site stores.
As a result of the efforts toward achieving the Medium-Term Environmental Conservation Targets 2025 for waste reduction, global production sites achieved a reduction of 2,300 tons of waste in FY2021 compared with the case where countermeasures were not implemented from the previous year. The economic effects of these measures reached 72 million yen. Waste discharge per unit of production in FY2021 improved by 32.6% compared to the base year (FY2014). The recycling ratio was 99.6% at production sites in Japan and 91.6% at production sites overseas.
Moreover, production sites in Japan have raised the utilization rate of electronic manifests to 97.1%, enabling real-time assessment of the reduction effects. We will continue to promote the reduction of waste through encouraging sharing of good reduction practices and visualization of waste by utilizing electronic manifests.

  • At the Kubota Sakai Plant, some of the wooden boxes and pallets used for test components imported from our Group company in China have been swapped for reinforced cardboard, helping to reduce wood scraps. Furthermore, we are taking steps to introduce reusable plastic pallets and to make wooden pallets returnable.

Improvement of Resource Efficiency

As the global population continues to increase and economic development progresses, resource consumption is expected to increase as well. Moreover, in recent years, the marine plastic pollution has become a global problem, as used plastic flows onto beaches and into the sea via rivers and so forth. The Kubota Group has been contributing to the formation of a recycling-based society by promoting improvement of waste discharge per unit of production and increases in the recycling ratio at its global production sites in the Medium-Term Environmental Conservation Targets 2025. In tandem with this, we have also set new targets for 3R(Reduce, Reuse, and Recycle) of waste plastic generated by business activities, and reduction of packaging and paper resource use.
The Kubota Group will continue to improve resource efficiency through initiatives such as effective use of resources throughout the entire business value chain and reduction of waste.

  • ■ Reducing Plastic Waste

    Based on the Medium-Term Environmental Conservation Targets 2025, we are reducing plastic use in our business sites, with a particular focus on single-use plastics. We are promoting efforts to reduce the use of plastic containers in cafeterias, plastic shopping bags at on-site stores, and PET bottle waste by encouraging people to bring reusable bottles.


    At Kubota Agricultural Machinery (Suzhou) Co., Ltd. (China), we ran an initiative to swap individually packaged drinks for fruit during environment month in June in a bid to reduce plastic trash.

  • ■ Reducing Resource Usage in Packaging and Adopting Returnable Packaging

    Based on the Medium-Term Environmental Conservation Targets 2025, we are collaborating with our business partners to reduce resource use in packaging materials and encourage adoption of returnable packaging in an effort to reduce waste discharge. At our business sites, we are promoting the replacement of stretch film and wooden pallets used for packaging components and so forth with reusable containers and packaging materials.


    At Kubota Precision Machinery (Thailand) Co., Ltd., we revised plastic film packaging for components and changed to reusable racks, which has reduced plastic and labor.

■ Transition to Paperless Operations

Under our Medium-Term Environmental Conservation Targets 2025, we are taking steps to transition to paperless operations with the goals of increasing operational efficiency and reducing environmental impacts. As workstyles shift from office work to telework (working from home) due to the COVID-19 pandemic, we have been promoting adoption of electronic systems for internal request approvals and determinations, and a reduction in documents stored in paper format. Moreover, we are also promoting effective use of office space and online meetings, enabling us to reduce the use of paper printouts. At our production sites, we have also made progress on switching to electronic check sheets and forms.

Handling and Storage of Equipment Containing PCB (in Japan)

Transformers, capacitors and other equipment containing polychlorinated biphenyls (PCB) are properly reported, stored and handled based on the Japanese Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes, and the Japanese Waste Management and Public Cleansing Law. Waste with a high concentration of PCB is being disposed of steadily, beginning with sites where PCB-treatment facilities are available. Waste with a low concentration of PCB will be properly disposed of by the disposal deadline of March 2027.
PCB-containing equipment in storage is thoroughly managed by multiple means, such as the locking of storage cabinets, periodic inspection, and environmental audits.
