Reduction of Materials and Resource Usage

Reducing Usage of Materials

We are working hard to reduce the amount of material that becomeポーカーテキサスaste after being introduced into the manufacturing phase. In addition to reducing and effectively utilizing natural resources, we also pursue the reduction of energy use, greenhouse gas emissions, and costs from material manufacturing to the processing of products.
　See below for information on our efforts for the effective use of key materials at each site.

• Efforts at JAE Site
To reduce the amount of material used in machining, JAE iポーカーテキサスorking to purchase materials in ideal sizes. In order to reduce the volume of gold used in gold plating in production, JAE is making ongoing efforts to implement efficiency improvements such as the management of the proper metal plating area and its thickness speeding up the process. At the same time, it utilizes reusable parts of production equipment and pursues the effective use of resources and the reduction of material and capital investment costs.

• Efforts at HAE Site
Molded waste (sprues, runners, and gates) generated during insulator and insert molding (*use cursor to view definitions) had previously been collected by contractors as a valuable resource, burned in thermal recycling, or re-pelletized at the request of outside parties. However, to expand the scope of the company’s recycling efforts, we have set an environmental target to crush molding waste, mix it with virgin materials, and use it as a mixed material (reglide), while managing the progress of this initiative. We believe that using mixed materials (reglide) is effective for both reducing waste and raw materials. “Fiscal 2023 effects: waste reduction of 160 tons (reduction of molding materials).”

●Efforts at YAE
We are continuously promoting measures ポーカーテキサスduce the amount of materials used by downsizing press molds, revising the width of metal materials used in presses, investigating the material yield, verifying and setting the minimum number of turns for plating, and performing early detection of key sample abnormalities. In addition, increasing the rate of reuse of molding materials, reducing input materials by promoting closed-loop-recycling of product waste, and cutting down on the volume of materials used by making spoolers/runners more compact, result in significant CO₂ reductions.

●Efforts at FAE
Efforts to improve the reuse rate for copper alloy electrode material used in the manufacturing process for mold parts (discharge machining) are contributing to a reduction in the quantity of material used, electric power, and the metal waste generated. It also introduced a special processing machine for cutting the plate material ポーカーテキサスduce the margin for grinding, enabling effective use of materials.

●Efforts at SAE
The SAE site continues to focus on reducing cutting processes. These efforts contribute to reduced metal waste, aポーカーテキサスell as lower CO₂ emissions during material production.

Conservation of Water Resources

Japan may appear to be a country with abundant water resources, but it is actually said to be one of the world’s largest importers of virtual water (*use the cursor to view definition). Around the world, we see explosive population growth aポーカーテキサスell as drought and other abnormal weather conditions that result in many people being unable to obtain one-tenth of the daily water that a person requires.
　The public expects companies to take initiatives to ensure the sustainable use of water resources. This is seen as a global issue, like others addressed by the Sustainable Development Goals (SDGs) adopted at the United Nations in 2015. As a responsibility of a manufacturer with a plating line that uses a large amount of water, we have continued ポーカーテキサスport our work to preserve water resources since our 2015 environmental report.
2015: Water input volume in sales per unit based on water conservation
2016: Water resource circulation balance was put into a visually readable format at JAE
2017: Water Risk Assessment (using WRI Aqueduct) at JAE compared with CDP, and water resource management goals and PDCA cycle compared with SDGs
Since 2018: Water data survey of the supply chain Understanding water consumption

Here are reported examples of reducing water usage and the status and challenges of new initiatives.

Examples of Reducing Water Usage
We will present some examples of activities conducted by the JAE Group in Japan and overseas ポーカーテキサスduce water usage through the protection of forests to conserve water resources, and the cleaning of rivers and seacoasts. (Items in parentheses are abbreviations of production site names.)

Water saving in production: Recycling water in the connector product plating line (JAE, HAE, JAE OR, JAE TW), on/off controls for water usage on each cleaning line, installing an evaporation prevention cover (JAE OR), changing water required for cleaning the plating line from running water to mist blown water (HAE), circulating pure water used for cooling chiller (HAE), and recycling water used for machinery and equipment (JAE TW). Also limiting users in processeポーカーテキサスhere large volumes of water are required for cleaning and creating specialized faucets that are opened with keys (JAE WJ).
Water saving in lifestyle: Adjusting water volume used in air conditioning cooling towers, recycling wastewater, using rainwater for toilets (JAE PH), using cooling tower drain water for toilets (JAE PH), changing from buried pipes that supply water for living to above-ground piping for the early detection of leaks and repair (JAE PH), educating about water saving using labels on water conservation in restrooms (JAE PH, JAE WX), adjusting the water volume discharged from faucets (JAE WX), installing meters showing how much water is used in cooling towers (JAE WX), raising water conservation awareness, and adopting water-saving sensors (JAE WJ).

Although the water input volume per unit is gradually decreasing due to the activities shown in the reduction example above, it appears that we need to take further steps to improve both production efficiency and reduction measures to prevent the impact of external turmoil such as deteriorating production efficiency caused by the COVID-19 pandemic that started in fiscal 2020.

Survey on water consumption
While considering policies to further reduce water usage, we surveyed consumption in the water circulation cycle at worksites. After surveying the amount of evaporation from production and air conditioning equipment, the amount of food and drink consumed at the Company’ポーカーテキサスelfare facilities, the amount of watering of areas of greenery, and the amount of evaporation from other facilities, we found that there was a difference between the estimates and meter readings in the amount of evaporation from the air conditioning cooling towers.
　Just as last year, as a result of checking the water supply, the difference was 5.5 times. A difference of 4 to 7 times, depending on yearly weather conditions, was expected, but the ratio of consumption to input, although gradually declining, has not changed much for the past five years, and is about 13%.
　Below are ポーカーテキサスnnual estimates of consumption by the domestic Group for the past five years, the breakdown for fiscal 2023.
　Measures to reduce water usage had a major effect on air conditioning equipment, so as an effective measure, we will install meterポーカーテキサスhenever possible to monitor and reduce the amount of evaporation.

FY	Consumption	Estimated evaporation/Measured value*	Consumption/Input
2019	38,894 m³	6.5	13.3 %
2020	40,916 m³	5.3	12.8 %
2021	42,970 m³	5.1	12.6 %
2022	40,377 m³	5.2	12.3 %
2023	43,240 m³	5.5	14.6 %
Evaporation from cooling/production	96.8%	(*) Results of a comparison of air conditioning cooling towerポーカーテキサスhere actual measurementポーカーテキサスere available.
Efforts for drinking water/food	2.9%
Watering plants	0.1%
Evaporation from water storage facility	0.2%

Contribution of the JAE Group Forest
Through the planting of Japanese cypress and broadleaf trees in the JAE Group Forest, we estimate that watershed replenishment is approximately 5,320 m₃ per year.
