Product Initiatives

Products that contribute to a sustainable society

Of the total CO2 emissions from the TEL value chain, emissions arising from product use account for 90% of our total CO2 emissions. For this reason, we have made it a key corporate objective to promote environmentally friendly product design, and lower the energy consumption of our products.

In fiscal 2015, we established a goal to reduce energy and pure water consumption by 10% by fiscal 2019, using fiscal 2014 consumption as the baseline. To achieve this goal, we are working to reduce energy use and improve overall throughput. As a result, we achieved the goal for one model in fiscal 2016 and three models in fiscal 2017 ahead of schedule. Moreover, even after achieving the goal, we have maintained our efforts for these models. For instance, in fiscal 2017 we achieved our 10% reduction goal for the Precio™ XL test system. Then in fiscal 2018, by switching to energy-efficient motors, we were able to reduce power consumption per wafer by a further 20%. In addition, in fiscal 2018, the percentage of sales from energy-saving models based on in-house standards was 92.8% of total product sales.

To further reduce the overall environmental impact of our products, we must examine our primary equipment, peripherals, associated facilities, and management at our customers’ factories. Going forward, it will become increasingly important to improve the operational efficiency of our equipment and encourage overall energy-efficient operations at our customers’ factories.

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 2018 were 122 kilotons, a significant increase from the previous fiscal year. This is because of the increase in product shipments compared to fiscal 2017.

*1 Modal shift: A change in the mode of transport; specifically, switching from conventional freight transport by truck or aircraft to a means that has a lower impact on the environment, such as rail or ocean.

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.
