WASHINGTON, July 14 — The mechanics of American recycling are undergoing a quiet but consequential recalibration, one that has more to do with global trade policy and capital flows than with household bins. The story of how the U.S. went from a 6.4% recycling rate for municipal solid waste in 1960 to 35.2% in 2017 — according to EPA data — is also the story of how a single Chinese policy nearly broke the system. The catch is that the system was already fragile.
Modern recycling in the U.S. traces its roots to World War II, when the government promoted scrap metal drives that collected 17 million tons of scrap in 1942 alone. That wartime mobilization set a template for organized collection.
The first curbside program followed decades later, in 1974, in University City, Missouri. By 1990, the EPA had set a national recycling goal of 25%, and the Recycling Advisory Council had formed in 1988 to coordinate efforts. The late 1990s brought a pivotal shift: single-stream recycling, where all recyclables go into one bin.
On closer reading, the mechanics here are straightforward but consequential. Participation rates rose sharply, but so did contamination — non-recyclable items mixed in with clean paper and bottles.
The trade-off was built into the model from the start. Then came 2018. China’s National Sword policy banned imports of most plastic and paper waste.
For years, the U.S. had shipped a significant portion of its recyclables overseas, particularly to China. The ban severed that market almost overnight. Prices for recovered materials collapsed, and municipalities suddenly faced higher costs for programs that had long been subsidized by foreign demand.
The disruption was severe, but it also triggered a response. Between 2018 and 2022, U.S. companies invested $1.2 billion in new recycling infrastructure, according to the Closed Loop Partners, an investment firm focused on circular economy projects.
That figure — $1.2 billion — represents a deliberate shift toward domestic processing capacity. The question now is whether that investment is enough. The U.S. recycling rate for municipal solid waste plateaued at 35.2% in 2017, and more recent data — through 2026 — is not yet available from the source material.
The catch is that contamination rates remain a structural problem, and the economics of recycling are still tied to volatile commodity markets for paper, plastic, and metal. Recycling has ancient roots — evidence of metal reuse dates back to 400 BC in Greece.
But the modern version, as it stands today, is a system built on a series of trade-offs: convenience versus contamination, domestic capacity versus global markets, participation rates versus processing costs. The $1.2 billion in infrastructure investment since 2018 is a significant sum, but it remains to be seen whether it can stabilize a system that was disrupted by a single policy shift in Beijing.
What to watch next: whether the new domestic processing capacity can absorb the material stream that once went to China, and whether contamination rates — the Achilles’ heel of single-stream recycling — can be reduced enough to make the economics work without foreign buyers.
