Quick Takeaways
-
Rising Demand: By 2050, health wearable demand could surge to 2 billion units annually, significantly increasing electronic waste and carbon emissions.
-
Environmental Impact: Current manufacturing practices could lead to over 1 million tons of electronic waste and 100 million tons of CO2, primarily driven by the devices’ printed circuit boards.
-
Key Contributors: The circuit board, responsible for 70% of a device’s carbon footprint, is mainly affected by intensive mining and manufacturing practices.
-
Sustainable Solutions: Researchers recommend using common metals like copper for chips and creating modular designs to reduce waste and improve sustainability in wearable tech.
Reality of E-Waste from Health Wearables
This week at CES 2026 in Las Vegas, tech companies showcased an array of wearable health devices, from glucose monitors to fitness trackers. While these innovations promise to enhance individuals’ health and well-being, they may also contribute to a significant environmental crisis. A recent study found that demand for health wearables could soar to 2 billion units annually by 2050. This figure represents an astonishing 42-fold increase from today’s numbers. If manufacturers do not change their production methods, these devices could generate over a million tons of electronic waste and emit 100 million tons of carbon dioxide.
Moreover, the main culprit is not the plastic we often associate with e-waste; it is the printed circuit board. This component, which acts as the “brain” of these devices, contributes 70% of the carbon footprint. Intensive mining and manufacturing processes largely drive these high emissions, highlighting the need for a shift in design and materials.
Possible Solutions for a Sustainable Future
Fortunately, researchers have suggested practical solutions to address this looming crisis. Firstly, using common metals like copper instead of rare minerals such as gold in chip production can significantly lower the environmental impact. Additionally, making devices modular allows for the reuse of circuit boards while only replacing the outer covering. These design changes seem small, but they can have a major impact when scaled globally.
As we embrace these health innovations, it’s essential to consider their long-term implications. Small design choices can accumulate to create significant environmental challenges. Therefore, while we celebrate technological advancements at events like CES, we must also advocate for sustainable practices. Balancing innovation and environmental responsibility will define the next chapter of our technological journey.
