The C175 ECO USB packaging adopts a common elevator design and the packaging is made of paper and can be disassembled and used without tools. This is also a consistent design feature of TeamGroup’s flash drive products.

The design of TEAMGROUP’s C175 ECO Net-Zero USB showcases a commitment to environmental sustainability through the incorporation of eco-friendly materials and thoughtful design features. TEAMGROUP has implemented a significant step towards sustainability by adopting a recycled material strategy in the production of the C175 ECO Net-Zero USB. The USB is composed of 75% post-consumer recycled material, a commendable effort in reducing the demand for new plastic and contributing to the circular economy. This design choice aligns with the global push for responsible resource management and reinforces the importance of recycling in electronic product manufacturing.

The C175 ECO Net-Zero USB goes beyond the use of recycled materials; it is designed with recyclability in mind. The materials employed in the USB are not only sourced from recycled content but are themselves recyclable. This comprehensive approach to material selection aligns with industry standards and environmental certifications, including RoHS, REACH, and ESG. These certifications signify the USB’s compliance with strict environmental protection guidelines, further bolstering its contribution to sustainability initiatives.

An innovative design aspect of the C175 ECO Net-Zero USB is the concealed click fastener mechanism, specifically implemented to address the issue of cap loss. The removable cap, a common feature in USB designs, is notorious for being misplaced, contributing to unnecessary waste. The inclusion of the click fastener design ensures that the cap is securely stored when not in use, minimizing the likelihood of loss. This seemingly simple yet effective feature not only enhances user experience but also aligns with the broader goal of Earth conservation by reducing the need for replacement caps and lowering overall product waste.
