Electronic waste, or e-waste, is a growing environmental concern. As our reliance on technology continues to increase, so does the amount of outdated or broken electronics that we discard. However, the landscape is changing, and the latest developments in biodegradable electronics offer a more sustainable solution to the e-waste problem.
Understanding the E-Waste Problem
Before we delve into the specifics of biodegradable electronics, let’s first understand the magnitude of the e-waste problem. As electronic devices have become an integral part of our lives, the amount of e-waste generated has also increased significantly.

In fact, according to a report by the United Nations, a staggering 53.6 million metric tons of e-waste was generated worldwide in 2019, and this number is expected to increase by 21% by 2030. This is not only an environmental issue but also a health concern as these electronic devices often contain toxic materials such as lead, mercury and cadmium, which can leach into the soil and water, contaminating them and posing serious health risks.
How can Biodegradable Electronics help?
The idea of electronics that can biodegrade, or break down naturally, may seem far-fetched, but recent developments in this field suggest that it’s closer to reality than you might think. Biodegradable electronics, also known as transient electronics, are designed to disappear or dissolve after a certain period of use, thereby reducing the amount of e-waste that ends up in our landfills.

Scientists are working on developing materials that can function like conventional electronic components but are made from substances that can biodegrade. For instance, research has been conducted on using silk and cellulose as substrates, instead of traditional non-degradable materials like silicon. These devices could serve a variety of purposes, from temporary medical implants to environmental sensors, before safely breaking down.
The Market for Biodegradable Electronics
The market for biodegradable electronics is still in its infancy, but it’s growing rapidly. According to a report from Transparency Market Research, the global biodegradable electronics market will reach $1.27 billion by 2026, growing at a compound annual growth rate (CAGR) of 51.9% from 2018 to 2026.
Several companies are already investing heavily in this technology. For instance, Samsung has committed to using more environmentally friendly materials in its devices, while Apple is exploring the use of biodegradable materials in its packaging.
In addition to large electronics companies, startups and research institutions are also exploring this field. For example, a company called Pulpworks designs and manufactures eco-friendly packaging for electronics from waste fibers.
Challenges and Future Directions
While the potential of biodegradable electronics is immense, there are several challenges that need to be overcome before this technology can be widely adopted. One of the main challenges is the lack of established disposal methods for these devices.
Although these devices are designed to be biodegradable, they can’t just be thrown in the compost bin. Instead, they require specific conditions to degrade, which are not available in most municipal waste management systems. Therefore, there’s a need for specialized recycling facilities that can manage these materials properly.
Another challenge is the durability and longevity of these devices. While the idea of electronics that degrade over time is appealing from an environmental perspective, it’s less so from a consumer perspective. Consumers are used to devices that last for several years, and may not be willing to invest in a product that’s designed to break down.
Despite these challenges, the future of biodegradable electronics looks promising. As technology advances and more research is conducted, we can expect to see more biodegradable electronic devices in the market. These innovations will not only help to reduce the amount of e-waste we generate, but also lead us towards a more sustainable future.
Therefore, while it is clear that there are still hurdles to overcome, the development and adoption of biodegradable electronics could represent a significant step forward in our ongoing efforts to reduce e-waste and its associated environmental and health impacts.
Jiva Materials and the Innovation in Biodegradable Circuit Boards
One company that deserves highlighting in the realm of biodegradable electronics is Jiva Materials. This London-based startup is leading the way with its innovative solution to the e-waste problem: biodegradable circuit boards.
Circuit boards are a significant contributor to e-waste. They are typically made using non-biodegradable materials like fiberglass and epoxy resins, and are filled with components like capacitors, resistors and transistors that can be difficult and expensive to recover and recycle.
Jiva Materials has developed a product called Soluboard®, a circuit board substrate that is not only non-toxic but also biodegradable. The Soluboard® is made from flax, a natural material, and a secret binding agent. When subjected to hot water, the binding agent dissolves, allowing the electronic components to be easily removed for recycling. The remaining flax material can then be composted, returning nutrients to the soil.
While the company is still in the process of scaling up its production, the impact could be transformative for the electronics industry. By replacing traditional non-degradable circuit boards with biodegradable alternatives, we could significantly reduce the volume of electronic waste and the environmental impact associated with its disposal.
However, like other biodegradable electronics, Soluboard® faces challenges related to waste management and consumer acceptance. The product requires specific conditions to degrade and the electronic components still require specialized waste collection and recycling. Moreover, educating consumers about the benefits of such a product, that may not last as long as traditional options, is crucial.
Toward a Circular Economy: The Role of Green Electronics
The development of biodegradable electronics fits into a broader vision of a circular economy. In contrast to the traditional linear economy model of ‘take-make-dispose’, a circular economy aims to keep resources in use for as long as possible, extract the maximum value from them while in use, and then recover and regenerate products and materials at the end of their service life.
Biodegradable electronics are a fundamental part of this vision. By designing electronic devices that are intended to biodegrade after a certain period, we can reduce the amount of e-waste sent to landfills, minimize the extraction of raw materials, decrease energy consumption, and lower greenhouse gas emissions.
Companies like Jiva Materials and major players in the electronics industry like Samsung and Apple are beginning to embrace this concept, but there is still a long way to go. The transition to a circular economy requires a concerted effort from manufacturers, waste management organizations, policymakers, and consumers.
In the electronics industry, this could involve designing products for longer life, facilitating repair and reuse, improving waste collection and recycling infrastructure, and promoting environmentally friendly consumer behaviors.
Conclusion
As we move further into the 21st century, the issue of e-waste will only continue to grow. However, the emergence of biodegradable electronics provides a beacon of hope. It presents an innovative way to tackle the increasing volumes of electronic waste and the associated environmental and health risks.
The market for these green electronics is still in its development stages, yet the potential for impact is massive. From startups like Jiva Materials creating biodegradable circuit boards to giants in the electronics industry committing to more eco-friendly practices, there are promising developments on the horizon.
Despite the challenges ahead, the rise of biodegradable electronics signals a significant shift towards sustainability in the electronics industry. A circular economy, in which electronic waste is minimized and resources are utilized effectively, may not be as far-fetched as it seems. As we continue to innovate and refine these technologies, we move one step closer toward a more sustainable future.
