Earth Smiles at Electronics Made from Wood and Silk

摘要

Consumer mobile electronics, such as smartphones, wearables, tablets and the like, are notorious for being less than Earthfriendly. For example, smartphones are typically made of non-renewable, non-biodegradable, and sometimes toxicmaterials like gallium arsenide used in RF circuits and LEDs. Compounding the problem is that smartphones are frequentlyupgraded or discarded, leading to serious environmental contamination.
