Environmental Management

Environmental Management Structure

OSG has formulated a company-wide environmental strategy and established an "Environmental Headquarters Committee" to proactively address environmental issues. The environmental management system is led by the departments close to the work site, which have a large environmental impact. The environmental management activities are organized by the director in charge of the environment as top management and the general manager of the Quality Assurance Department as the overall environmental management representative.

Environmental Performance and Targets

OSG drafts Medium-Term Environmental Plan every three years. FY2024 is the final year of our 9th Medium-Term Environmental Plan, which included the four management metrics of (1) Eco-Factories (eco-friendly manufacturing), (2) Eco-Products (development of environmentally friendly products), (3) Energy improvement and reduced usage, and (4) CO₂ emissions reduction. As a result of efforts, we were able to meet each of these four targets.

Reducing Environmental Impact with Thorough Management of Waste and Visualization of CO₂ Emissions

OSG is working to lower its environmental impact by improving how we manage waste and monitor CO₂ emissions.
We've made our waste tracking system clearer, so we can see what types of waste we produce, how it's handled, and where it comes from.
This helps us follow regulations and understand our impact more accurately.
With this data, we're taking steps to reduce waste, increase recycling, and cut CO₂ emissions.
We're also planning to connect waste and emission data to build a smarter, more sustainable system.
We are committed to contributing to a recycling-oriented society through environmentally conscious corporate activities.

Environmentally-Conscious Product Transport

Our logistics departments replaced the cushioning material, which is used when products are transported to our customers, with an environmentally-friendly material. We found a cushioning material that would ensure safe transport and eventually opted for paper packaging for heavy items. After use, the paper packaging can be recycled. Air cushions made by thin film are also used, which do not produce toxic substances when incinerated. Our customers previously commented that cushioning material was bulky and difficult to dispose of. The new air-cushioning material makes it possible to reduce the amount of waste just by letting the air out. Also, we used to wrap pallet cargo with multiple layers of film to prevent the cargo from dislodging during daily shipments from our Shinshiro Factory to Logis Tokyo. However, we have eliminated this method and adopted a new one, which involves covering the entire pallet with a box assembled from five panels. These panels can be used repeatedly, so they reduce waste. As they can also be stacked, additional transport trucks no longer need to be dispatched depending on the volume of cargo. This makes our transport more efficient.

Showcasing an Environmentally Conscious Product

GREEN TAP (GRT) is an innovative OSG forming tap that is a low-carbon product. Our new manufacturing method allows for reduced power consumption during tool manufacturing, which in turn achieves lower CO₂ emissions.
After first announcing GRT in 2023, we carried out additional innovation of the tool shape and coating, then launched the latest GRT in November of 2024. Compared to conventional forming taps, GRTs save 35% in CO₂ emissions, thanks to lower power consumption during tool manufacturing.

Feature #1

Special thread configuration increases cooling effects.

Conventional designs have oil groove walls that impede the flow of cutting lubricant.
This is akin to the aerodynamic disadvantages of a large truck. Although the conventional tool had oil grooves, lubricant was not getting to the cutting edge, which brought the risk of tool damage.

For this reason, we used fluid analysis to design a smooth cutting lubricant path to deliver more lubricant closer to the cutting edge, where the most heat accumulates. As shown in the illustration on the right, the more streamlined tap geometry improves the cooling effect, such that the tap is less likely to break even without oil grooves.

Feature #2

Large web diameter for high rigidity

Compared to cutting taps, forming taps undergo greater machining loads and may break under extreme machining conditions. It takes extra time to remove a broken tap and this creates more work for customers. With this in mind, GRTs not only eliminate oil grooves, but also have a larger cross-sectional area, which allows for substantial improvement in resistance to breakage. This feature of GRTs delivers high durability without variation.

Feature #3

Stable female screw thread formation

GRTs feature a special thread specification designed using computer simulation of plastic deformation. Using numerical analysis, we devised the most rational design while pursuing the ultimate answer to what makes the optimal forming tap.
The result is OSG's unique and special thread specification that enables the formation of good internal female threads that will not collapse easily. This is the background to the very distinctive geometry of GRT.
