Leo Baekeland’s invention of Bakelite in 1907 was a pivotal moment in the history of materials, marking the transition from plastics based on modified natural substances to the first truly synthetic resin. By successfully controlling the phenol-formaldehyde condensation reaction, Baekeland created a durable, heat-resistant, and electrically insulating material that revolutionized industrial manufacturing.12

This innovation launched the modern plastics industry, as Bakelite offered a stable, non-flammable alternative to earlier materials like celluloid. Its versatility allowed it to replace shellac and rubber in electrical components, appliances, and automotive systems.1

However, this breakthrough also set the stage for the global challenge of plastic pollution. Because Bakelite introduced synthetic resins into world commerce, it initiated a trajectory of mass-produced, persistent materials. By the end of the 20th century, the widespread adoption of such synthetic polymers led to their accumulation in diverse environmental niches, creating significant hazards for wildlife, human populations, and global ecosystems.3
