HURTLING THROUGH THE E-WASTE FRONTIER: Veena Sahajwalla’s 3D-Printed Plastic Revolution

Strap on your goggles, dear reader, because we’re about to fire up the extruder and plunge into the heart of Veena Sahajwalla’s radical journey: turning discarded electronics into high-grade 3D-printing filaments . The scene flickers like a late-night fever dream—piles of shredded circuit boards, keyboards, and plastic shards feed into machinery that hums like a restless beast. In this makeshift temple of innovation, mechanical marvels and chemical alchemy collide to produce filaments strong enough to thumb their noses at traditional plastic recycling. Hang on tight. Sourcing the Plastic Gems: Raw Material Selection & Preprocessing This quest begins in the electronic underworld, where cracked printer housings and battered keyboards hold hidden pockets of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) (Gaikwad et al., 2018). Instead of consigning them to a smoldering landfill, sorting, shredding, and cleaning transform these...
