Products that Contribute to a Sustainable Society

Of the total CO2 emissions from TEL’s value chain, emissions during product use account for 90%. For this reason, TEL has made it a key corporate objective to promote environmentally friendly product design, and lower the energy consumption of its products. In fiscal year 2020, we set a medium-term environmental goal for the key models of each business unit (BU), namely, to reduce per-wafer CO2 emissions by 30% by fiscal year 2031 (compared with fiscal year 2014). Furthermore, in order to achieve this medium-term goal, we set an interim goal of reducing per-wafer CO2 emissions for the key models of each BU by 20% by fiscal year 2025 (compared with fiscal year 2014), and we have been promoting specific activities. In fiscal year 2020, we formulated a roadmap for achieving this goal for our key models, and we established guidelines for calculating CO2 emissions, incorporating the usual energy and water usage, as well as process gas and chemical substance usage, product footprint, volume, and weight, reduced frequency of parts maintenance and increased lifespan, and shorter time to equipment launch. Based on these guidelines, the reduction in CO2 emissions for equipment shipped in fiscal year 2020 in comparison to baseline equipment was calculated as 16%. We also began examining environmental technology strategies for achieving our medium- and long-term environmental goals. As we work to further raise environmental awareness, we will continue to incorporate environmental technologies as an important added value in our technological strategies. We will continue to promote further activities for achieving our medium- and long-term environmental goals.

Logistics Initiatives

Environmental Considerations in Logistics

Because of worldwide environmental concerns such as global climate change and the rising demand to reduce the environmental burden of logistics activities, transportation regulations are becoming more stringent. TEL continues to adjust its logistics operations to meet these demands.

CO2 Reduction Initiatives

TEL’s CO2 emissions from domestic logistics operations are monitored and calculated within the scope of regulation defined by the Act on the Rational Use of Energy. In our overseas logistics operations, CO2 emissions are monitored and calculated based on the data from our intra-company logistics and product shipments to customers.

TEL has been implementing modal shifts*1 to transportation methods that are less environmentally harmful, where applicable. For example, we have adopted ocean shipment for some semiconductor and FPD production equipment and are making efforts to reduce production lead time to compensate for the extra time it takes to ship by ocean rather than by air. We have extended the use of shelved trolleys from the shipment of FPD production equipment to semiconductor production equipment as well, thereby improving the load factor of trucks and reducing both CO2 emissions and cost.

Our CO2 emissions in fiscal year 2020 were 186 kilotons, a significant increase from the previous fiscal year. This is because of the increase in product shipments compared to fiscal year 2019.

Resource-saving Initiatives

Because TEL’s products are precision equipment, they must be shipped with care and in clean conditions, requiring the use of wooden crates and cardboard boxes. To conserve some of these resources, TEL uses recyclable cardboard boxes for packaging. After the equipment has been shipped and installed, casters and other specialized transport fixtures are collected and brought back to TEL factories for reuse. These are only a few examples of TEL’s resource-saving efforts.

Product Reuse and Recycling

With the advent of the Internet of Things (IoT), semiconductors are in greater demand and are becoming more diverse than ever. This has driven a corresponding rise in the need for more varied semiconductor production equipment. As a leading manufacturer of semiconductor equipment, TEL is strongly encouraging reuse and recycling of equipment and components by marketing refurbished TEL equipment and offering modification services to customers who already have TEL equipment installed. Our refurbished equipment operations start with procuring used equipment from the market, which takes place either directly or through leasing companies. This equipment is then properly tested and refurbished, before being offered to customers as TEL Certified Used Equipment.

Our equipment modification services boost the productivity of installed equipment by maintaining and improving its quality and availability. Through these approaches, we address our customers’ cost, speed, and performance needs, while also contributing to waste reduction and resource conservation and utilization. These efforts help reduce the use of resources and CO2 emissions associated with procuring and manufacturing equipment and components. They are also effective in reducing the costs of production, logistics, and waste disposal.
