Technologies
The influence of product specifications on the environment is deeply related to the development and design phases of the product. To lower our environmental burden, JTEKT must oversee entire products life cycle from raw material procurement, specifications to the customer, and to disposal. We must also take responsibility to make environmentally-friendly designs which allow products to be easily reused and recycled. JTEKT believes that our products and technologies provide environmental countermeasures for our customers’ products and manufacturing processes and, as such, greatly contribute to the environment. Therefore, we endeavor to improve the environmental performance of each product through the entire product lifecycle, and are contributing to the prevention of global warming and the effective use of resources.

Report of Activities

Promotion by the Environmental Responsible Products Subcommittee

The Environmental Responsible Products Subcommittee promotes development of environmentally-friendly products together with the group companies in Japan. Innovative technology is incorporated in the development and design stages to make products smaller, lighter, and more efficient, as well as reduce the amount of environmentally-burdensome substances and raw material usage. In this way, JTEKT is engaging in environmental conservation on a global scale through its products.

Contribution to CO2 reduction through products

JTEKT is working to improve product efficiency to meet its target of making its contribution to CO2 reduction through products, by FY2020, by 800,000 t or more. In FY2018, the result of JTEKT’s endeavor was 816,000 t.
*Contribution to CO2 reduction volume through products is calculated globally for each fiscal year.
*In FY2016, the method for calculating reduction volume was partially changed.
Assessment method

JTEKT has established its own formula to calculate environmental efficiency, and the formula is used as an index of quantitatively assessing the reduction volume of environmental burden. The value calculated by the formula indicates how much the environmental burden is reduced. Each year, JTEKT sets higher targets and endeavors to achieve it, monitoring the achievement level.

●Environmental efficiency basic equation and environmental efficiency value calculation
Environmental efficiency is a value calculated based on the degree of lightness, compactness, energy-savings, etc. The environmental efficiency value is calculated by dividing the environmental efficiency of the assessed product by that of the standard product. ●Calculation of environmental load reduction effect
As the environmental load reduction effect, it is possible to seek environmental load reduction ratio more than the environmental efficiency value. For example, if the environmental efficiency value was 1.25, that product’s environmental load reduction benefit would be 20%.A reduced environmental load is sought as the reverse of the environmental efficiency value.

3R initiative

JTEKT promotes environmental design activities with close interaction between each business headquarter and the group company by setting targets by individual product for weight reduction, longer product life, downsizing, etc. Through incorporating creative ideas such as these from the design stage, the products of the JTEKT group are contributing to the reduction of environment burden on global basis.

●3R
The term “3R” originates from the first letters of the words “Reduce” (minimize waste generation), Reuse” and “Recycle.” It is a concept concerning the order of waste minimization priority.

Space-saving and weight-saving through development of the magnetic separator MX-1000A

The maximum processing flow rate of the current magnetic separator was up to 500L/min but increasing the drum diameter and the wetted distance yielded a new separator (MX-1000A) with reduced installation space and a capacity to process 1000L/min Compared to a central coolant system (one coolant system for multiple processing machines) of 500L/min x 2 units, installation space was reduced by 15.8% and the weight reduced by 10.7% (equivalent to 1,413 kg/year of CO2).

Environmentally friendly product development
The Driveline Systems Business Unit develops environmentally friendly products such as pressure reducing valves used in FCVs, electric oil pumps for idling stop vehicles, and ITCC for on-demand 4WD. To make such developments possible, our department operates and manages daily development progress, substances of concern, roadmap development assessment, and more so that the development department can carry out product development smoothly. The automotive industry is currently said to be in a major period of reform that comes once every 100 years, and as progress is made on CASE (*1) and MaaS (*2), contributions to the global environment are increasingly expected. To meet these expectations, we will continue to strive to create even more environmentally friendly products.
