Where Does Plastic And Other Trash Go After We Throw It Away?

November 25, 2025

Key Takeaways Copied to clipboard!

  • While materials like steel and cardboard have genuinely circular economies, plastic recycling is inefficient, often toxic, and less than 10% of all discarded plastic has ever attempted the recycling process. 
  • The global trash trade operates similarly to organized crime, profiting by shipping toxic waste from wealthy nations with strict disposal laws to poorer countries with lax regulations, a practice exacerbated after the Basel Convention by relabeling toxic waste as 'recyclable resources.' 
  • For plastic waste, the author suggests that landfilling (where it is buried and contained) might be a more honest, less harmful solution than exporting it for dangerous, polluting 'recycling' in developing nations, emphasizing that the core issue is overproduction, not just consumption.

  • Key Takeaway: The author’s investigation into the trash trade began after witnessing unexplained stacks of plastic waste on a roadside in Romania.
  • Summary: The author spent two years traveling to five continents to chronicle trash travel, driven by initial curiosity about waste disposal. The turning point was seeing plastic waste on the side of a road in Romania, which was traced back to France and Germany. This revealed a contradiction between rich nations’ environmental claims and their waste export practices.
Recycling Effectiveness and Plastic Issues

  • Key Takeaway: Plastic recycling is problematic because it is rarely profitable compared to virgin plastic production, and the process releases toxic additives into local environments when processed in poorer countries.
  • Summary: Materials like steel and cardboard are genuinely recyclable, forming circular economies. Plastic recycling fails because it is unprofitable and inefficient; less than 10% of all discarded plastic has even attempted recycling. The mechanical reduction of plastic in poorer countries unleashes thousands of toxic additives into local soil, water, and food systems.
Actionable Advice on Plastic Use

  • Key Takeaway: If plastic must be used, landfilling it domestically might be the more honest solution than exporting it, as it avoids contaminating foreign environments with microplastics.
  • Summary: Listeners should prioritize avoiding avoidable plastics entirely. When plastic use is unavoidable, landfilling it domestically—where it is buried in lined landfills—is suggested as better than exporting it. Exporting plastic prevents unleashing contaminants into water systems or food chains in countries like Vietnam or Thailand.
History of Disposable Culture

(00:08:00)
  • Key Takeaway: Modern disposable culture, especially the rise of plastic, began in the 1950s, shifting waste from being seen as a loss to a sign of prosperity and progress.
  • Summary: Before the 1950s, societies prioritized reusing materials because waste represented a loss. The post-WWII era, particularly in the US, embraced a disposable culture fueled by plastic, where high waste output signaled societal progress. Plastic itself was often imposed on society through advertising, creating uses for materials people did not need.
Waste as a Shipped Product

  • Key Takeaway: Environmental legislation in the 1970s made domestic toxic waste disposal expensive, creating a profit incentive to ship waste overseas to unregulated countries.
  • Summary: Legislation in the 1970s made disposing of toxic chemicals prohibitively expensive in the US, but these rules did not apply abroad, leading to cheap disposal in places like Africa. This created a geography of legislation that incentivized shipping waste overseas. Later, the Basel Convention (1994) made shipping toxic waste illegal, prompting the trade to reclassify waste as ‘resources’ to continue shipping it.
The Role of Middlemen Brokers

  • Key Takeaway: Waste brokers operate under the radar, profiting by exploiting the gap between expensive domestic disposal costs and cheap international shipping to poorer nations.
  • Summary: Waste brokers often operate in kinship networks, making them difficult to access, and they profit from the privatized fate of publicly collected trash. They ship material like plastic to countries like Indonesia, where labor is cheap and environmental costs are ignored. Germany, for example, ships plastic to Turkey, where much of it is burned or dumped despite Germany claiming it is recycled.
Accountability and Solutions for Plastic

(00:18:04)
  • Key Takeaway: Solutions require holding plastic producers accountable through regulation, stopping the export of waste to poorer nations, and reducing plastic production at the source.
  • Summary: The plastic industry is planning to triple production by 2060 despite knowing the dangers of plastic contamination in human bodies. Solutions must involve regulation, such as quotas or making production less cheap, and enforcing the principle that ‘you discard it, you own it’ to stop waste export. Relying solely on scientific fixes like plastic-eating microbes is a distraction that lets producers off the hook.
Personal Impact of Waste Reporting

  • Key Takeaway: Reporting on waste travel revealed that discarded items are not inert but travel to foreign countries where desperate people are exposed to dangerous contaminants.
  • Summary: The author realized that waste is not inanimate but travels, often exposing desperate people in foreign countries to dangerous breakdown products. While essential plastics exist (e.g., medical), consumers should avoid avoidable plastic for personal health reasons. Plastic is now found in human brain tissue and bloodstreams, making avoidance a personal health imperative.
