The rapid advancement of technology has led to an unprecedented increase in electronic waste, commonly referred to as e-waste. This phenomenon is characterized by discarded electronic devices, including smartphones, computers, televisions, and other gadgets that have reached the end of their life cycle. According to the Global E-Waste Monitor 2020, approximately 53.6 million metric tons of e-waste were generated worldwide in 2019, a figure projected to rise to 74 million metric tons by 2030.
This staggering amount of waste poses significant environmental and health risks, as many electronic devices contain hazardous materials such as lead, mercury, and cadmium. When improperly disposed of, these substances can leach into soil and water systems, leading to contamination and adverse health effects for both humans and wildlife. The issue of e-waste is compounded by the fact that only a small fraction of it is recycled properly.
The United Nations estimates that only 17.4% of e-waste was collected and recycled in 2019. This low recycling rate is attributed to various factors, including a lack of awareness among consumers about proper disposal methods, inadequate recycling infrastructure in many regions, and the complexity of dismantling electronic devices for recycling. As a result, a significant portion of e-waste ends up in landfills or is incinerated, further exacerbating environmental pollution.
The urgency to address this growing problem has led researchers and innovators to explore alternative solutions, one of which is the development of biodegradable electronics.
