Summary
Highlights
Plastic bottles begin their life in oil refineries, where oil and gas molecules are chemically bonded to create monomers. These monomers form long polymer chains, which are then processed into millions of plastic pellets. These pellets are melted and molded into resilient bottle shapes, filled with liquid, consumed, and then discarded.
Bottle one ends up in a landfill, contributing to ever-expanding dumps. As plastics are compressed with other waste, rainwater flows through, absorbing toxic compounds to create a harmful stew called leachate. This leachate can contaminate groundwater, soil, and streams, poisoning ecosystems and harming wildlife. Plastic bottles can take an estimated 1,000 years to decompose in a landfill.
Bottle two's journey takes it from streams to rivers and eventually into the ocean. It becomes part of a massive vortex where trash accumulates, like the Great Pacific Garbage Patch, one of five such plastic-filled gyres in the world's seas. Animals become entangled in the plastic or mistake it for food, leading to starvation and the transfer of toxins up the food chain, ultimately reaching humans. Most plastics don't biodegrade, breaking down into smaller and smaller microplastics that can perpetually remain in the sea.
Bottle three is spared the fate of its counterparts through recycling. It's brought to a plant, compressed, shredded into tiny pieces, washed, and melted. This process transforms the plastic into raw materials that can be reused, allowing bottle three to be reborn as a completely new product.
