Circular Economy


Wistron seeks to maximize benefits for customers in the circular economy by not only producing green electronic products, but also recycling discarded electronic products and converting recycled materials into environmentally friendly products. We use resource sustainably to create a green and circular sustainable business model. The service targets of closed-loop gold and closed-loop plastic have expanded from the information and communication industry, medical industry, and aviation industry, to the “safe product destruction and recycling” services requested by OEM clients. Product lines that use recycled plastics have gone from display products and televisions to desktop computers, VoIP phones, servers, set-top boxes, mice, and keyboards.

Green resources business achievements (tons)

Raw Materials and Technological Innovations


The Wistron green resources team provides recycle processing and recycled plastics services, building on its 9 years of practical circular economy experience. At the same time, we have assisted customers to introduce 50% PIR (post industrial recycled) hydroelectric recycled aluminum in 2021 to satisfy their aluminum needs. Additionally, recycling and reuse of lithium batteries will be the focus of next phase of developments.

Raw materials/technologies Characteristics and environmental benefits
Renewable raw materials Bio-based Plastic The addition of bio-based plastics does not impact the structural strength and can improve sustainable content. Currently, the main source of bio-based plastics is castor oil from renewable plants. The addition ratio is between 20% to 50% (bio based mass balancing). Besides reducing the use of petroleum, it can reduce carbon emissions without weakening the structural strength.
Ocean-bound plastic Ocean-bound plastic has been used in product development for products such as display products and fans. In 2021, 102 tons of products made from ocean-bound plastic were shipped.
Innovative technology Hydroelectric recycled aluminum Traditional aluminum is mostly made from fossil fuel power. 50% PIR recycled aluminum have been introduced through recycling and reuse because the energy consumption of recycling aluminum is much lower than producing new aluminum. Additionally, the carbon dioxide emissions of producing 1 ton of aluminum through hydropower are much less than fossil fuel power. This will also help achieve energy conservation and carbon reduction goals
Recycling and reuse of lithium batteries When recycling and refining lithium batteries used in consumer products, lithium batteries used in electric vehicles can also be recycled. We are committed to the full implementation of the concept of circular economy.

Green Product Performance


The product design and development process complies with the “Guidelines for Green Product Design and Review Procedure” and considers waste reduction, environmental protection, and the use of non-hazardous materials. Besides meeting international regulations and standards, we are also dedicated to minimizing our impact on people and the environment. Wistron’s Green Resources Business subsidiary focuses on the recycling of waste electronics and refining of renewable plastics, promoting post-consumer recycled (PCR) plastics for various customer products and expanding the influence of Wistron’s green products.

  • Note: Data and examples of packaging designs using recycled materials before 2020 in Wistron Technology

Wistron's product packaging has always been based on the concepts of environmental protection and reduction of resource waste. We choose recyclable and reusable materials for cardboard boxes, cushioning materials, and ink used for printing whenever possible. We also make use of this feature to add recycled and reproduced materials at the source for production. In 2021, the products that used Wistron's packaging design with recycled materials accounted for 98% of hardware revenue. Among which, 96.7% of the external boxes were made from recycled pulp; 92.7% of the cushioning materials were made from recycled EPE; and 96.6% of the printed materials were printed with environmentally friendly water-based ink. They significantly reduced the impact and destruction of the environment.
