Globally, only about 20% of electronic waste is currently recycled. Electronic waste in landfills creates risks due to toxic materials. Circularity requires holistic integration and material selection in manufacturing, and global collaboration. 

Electronic waste is a growing global challenge, with only about 20% currently recycled. The vast majority of electronic waste ends up in landfills, creating significant environmental and health risks due to the presence of toxic materials. An integrated approach to address this challenge is needed across the entire product lifecycle. Current manufacturing processes, largely driven by "Moore's Law" and a focus on performance, are resource-intensive, often utilizing toxic chemicals, vast amounts of water, and high energy levels. 

The industry frequently employs a "one-size-fits-all" design philosophy, leading to unnecessary electronic complexity and rapid obsolescence. Inherently wasteful subtractive manufacturing techniques, such as lithography, should be replaced wth more resource-efficient additive methods, like printed electronics 

Some aspects of finding sustainable solutions for true circular electronics: 

Holistic Integration: look at the entire chain -- materials, design, manufacturing, use, and end-of-life -- as missing any part breaks the cycle. 

Material Selection: carefully select eco-friendly or bio-based materials, and rigorously test their degradation products. 

Policy and Collaboration: Policies like "right to repair" legislation represent positive steps. 

Global collaboration across different regions is needed to avoid fragmentation.
