Establishment of
a Recycling Society
Preservation of the world’s resource bases is a major theme of ISO26000, GRI Standards 2016, and Sustainable Development Goals (SDGs). There is also a strong demand on companies to reduce their usage of raw materials and to utilize recycled parts. In addition, due to the concern of global water shortages in the future, it is becoming increasingly important for companies to engage in activities for the effective utilization of water resources. At JTEKT, through promotion of production technology innovations, reduction of production processes and subsequent reduction of materials, and improvements and ingenuity at the production site, we are proceeding with various initiatives to reduce waste and reuse and recycle resources including water.
Main FY2020 results
Waste output in production (independent)6.26 t/100 million yen (25.1% decrease)
Waste output in production (global)9.21 t/100 million yen (10.9% decrease)
Water usage by in-house production  (independent)1,290 m3/100 million yen (28.9% decrease)
Water usage by in-house production   (global)1,080 ㎥/100 million yen (51.6% decrease)


Activities to reduce marine plastics

JTEKT is deeply concerned about the impact of microplastics on the marine ecosystem. In addition to social contribution activities such as cleaning beaches and rivers, JTEKT will continue to reduce the use of plastics in production and logistics and replace materials as we proactively work to solve the problem of marine plastics.
Discontinuing use of plastic shopping bags at shops in all JTEKT plants
In line with the plastic shopping bag fees that became a requirement starting in July 2020, JTEKT discontinued distributing plastic shopping bags at the shops operating at each plant and has replaced them with paper bags made from paid recycled paper. As a result, we reduced about 180,000 plastic shopping bags, weighing about 1.8 tons, per year.
Participation in CLOMA (Clean Ocean Material Alliance)
Since 2020, JTEKT has started participating in the Clean Ocean Material Alliance, which was established as a global platform that strengthens collaboration across industries and accelerates innovation to solve the new global problem of marine plastic pollution.
Through participation in CLOMA, we will work to solve the marine plastics problem by exploring the possibility of using alternative materials such as biodegradable plastics and accelerating collaboration with companies across industries.

Initiatives for achieving Zero Emissions
JTEKT considers all discharged materials, including waste, to be resources, and we have been working to achieve a 100% recycling rate based on the concept of 3R (Reduce, Reuse, Recycle).
JTEKT alone achieved the 100% recycling rate in November 2012, which we have maintained ever since. We will formulate and promote plans for each region in order to achieve zero emissions on a company-wide basis.
・What is “Zero Emission”?
The practice of utilizing waste and byproduct created through industrial activities as resources for other industries in an attempt to avoid releasing waste into the natural world on the whole. This concept was proposed by the United Nations University in 1994.

Initiatives for reduction of primary material consumption
JTEKT is reducing material consumption through the application of the net shape method (contributing to reduction of machined portions), which improves the technologies related to casting and forging.
Activity Details

Yield improvement through TRB scrap reduction

In the forging process of TRB (tapered roller bearings), JTEKT is working to reduce the amount of input material and scraps through diameter-expandable burring (forming down) in the forming process.
Reduced weight
Approximately 193 t/year
Initiatives for reduction of secondary material consumption
JTEKT is reducing the consumption of secondary materials such as dies, magnets, and cutting tools, by changing the material, shape, hardness, and other specifications to increase durability. JTEKT also promotes recycling by reproducing, reusing and so on.
Activity Details

Improved die (punch) life through optimization of plastic flow

During the forming process by the warm forging press, lubricant becomes trapped between the coarse material and the die, residual moisture rapidly increasing the pressure load and shortening the product life of the die.
By optimizing the shape of the punch so that the material smoothly spreads from the center of the punch outward to prevent enclosure of the lubricant, the product life of the die was improved.
Die product life
Approximately 10 times longer

Waste reduction

Reduction of packaging materials
To promote the reduction of paper packaging materials increasing in FY2020, JTEKT achieved reductions through activities, including reducing the amount of cushioning material by replacing disposable cardboard boxes with returnable plastic cases, reviewing excess packaging, and using cardboard boxes to fit the product size. In FY2021, JTEKT strives to achieve a wooden packaging material base unit of 0.35 t/100 million yen and paper packaging material base unit of 0.36 t/100 million yen.

In FY2020, JTEKT worked on consumption results management of waste plastic packaging as part of its SDGs activities. As part of packaging improvement efforts, JTEKT achieved plastic reduction by expanding replacement of cardboard boxes with plastic cases, vacuum packaging of leather-wrapped large-size bearings, and using cardboard boxes for HUB trays. JTEKT’s future reduction target for plastic packaging materials is to achieve a 10% reduction by FY2025 based on the FY2020 base unit (considering the effects of COVID-19).

Effective utilization of resources
<Reduction of water consumption>

Promoting the effective utilization of water

To reduce the usage of water, a precious resource, we engage in internal activities to decrease wasteful usage and recycle water. In FY2020, we had at first planned to improve our base unit and consumption amount by 8% or more compared to FY2012; however, we achieved this goal ahead of schedule in FY2019, therefore setting the new target to improve the figure compared to FY2019 by 0.5% or more. As a result, although the basic unit worsened by 3.7% (40 m3/100 million yen) due to the production decrease caused by the COVID-19, we were able to reduce the usage by 14.5% (271,000 m3). With the aim of achieving an improvement of 3.0% or more compared to FY2018 in FY2021, we will promote a decrease in consumption mainly through leakage control.

Water risk assessment

In addition to effectively using water resources by improving the water consumption base unit, JTEKT has been assessing water risks at each business site using Aqueduct* since 2017.JTEKT will continue to work to reduce water consumption and effectively use water resources through activities based on water risk assessment results including future predictions and water consumption and water dependency at each business site.
A database operated by the World Resources Institute (WRI) that provides world maps and information showing water risks such as physical water stress, water quality, regulatory risk concerning water resources, and reputational risk.
*Target companies for data collection : Company-wide environmental management companies (JTEKT independent 13 bases, 20 domestic group companies, 39 overseas group companies)

Water risk countermeasures

As a result of water risk assessment, the Indian region and the Dalian China region were rated as having high water stress in all of JTEKT group’s production bases.
On top of that, as a result of investigating the actual water usage and water situation in each region, because the water quality is poor in the Indian region, the RO (reverse osmosis) membrane device was installed to improve the water quality before supplying water to production.

Water stress situation

Please refer to the graph below for changes in water usage in water stressed regions. Water usage in stressed regions in FY2020 were 106,000 m3 in India and 27,000 m3 in China, which was a relatively small proportion of the entire JTEKT group at 2.8%. It is judged that the risks associated with water use are limited. For this reason, JTEKT is currently working to reduce the amount of water consumption at business sites that use a large amount of cooling water sourced from groundwater and rivers.

Water Management Solution (J-WeLL)

JTEKT has started to sell its water management solution (J-WeLL) from 2019.
This initiative provides a mechanism for managing wells, which is a water source, with the aim of extending the life of the well in order to continuously supply water to people in areas where it is difficult to obtain industrial and domestic water due to water shortages. To contribute to the achievement of SDGs Goal 6 and help develop an environment where people who are troubled by water shortages can use water with peace of mind, JTEKT integrates our water level gauge and control technology into a system that “visualizes” the condition of the well.

Plant: JADS France

Water reuse through introduction of a waste water treatment system

JADS manages 1,150 tons of sewage from washing and processing machines annually. Until now, the entire amount was treated as waste (wastewater), but with the introduction of the evaporator, a wastewater treatment device using the vacuum distillation method, the wastewater at the plant is concentrated and purified, reducing water usage by 240 m2/year and 38 t/year of waste from wastewater. The distilled water is reused to clean plant floors and is being considered for reuse in processing line washing machines and toilets. Reducing the use of wastewater collection trucks and reusing recovered energy to heat the plant has also led to a reduction of CO2 emissions of 3.05 t-CO2/year. Along with the reduction of natural resources, JADS will continue activities to further reduce water consumption.

Striving for proactive environmental management by the entire plant
I had been in charge of energy management, but from 2019, I am also in charge of environmental activities (i.e., waste, wastewater, facilities cleaning). Sharing best practices with other plants and through various reductions and efficiency improvements, I am working to develop unity and exchange between plants. I would also like to strengthen information sharing about JTEKT’s environmental responsiveness and promote JTEKT’s aggressiveness in the environmental field in addition to our expertise in automobile parts.
