UN Expert: US Using Mexico as a Toxic 'Garbage Sink' 2026

MEXICO CITY — A United Nations special rapporteur has issued a blistering indictment of the United States’ waste management practices, accusing Washington of treating Mexico as a “garbage sink” for its hazardous materials. Following a two-week fact-finding mission across industrial border zones and coastal dumping sites, Marcos Orellana, the UN expert on toxics and human rights, warned that the “unchecked flow” of electronic waste, plastic scrap, and industrial chemicals has triggered a “toxic crisis” that is systematically violating the right to a healthy environment for millions of Mexicans.

The report, presented to the UN Human Rights Council on Tuesday, highlights a disturbing trend of “waste colonialism” facilitated by the loopholes in the US-Mexico-Canada Agreement (USMCA). Orellana noted that as the US tightens domestic environmental regulations, American companies are increasingly offloading their environmental liabilities south of the border. This includes thousands of tons of lead-acid batteries and “forever chemicals” (PFAS) that are processed in Mexican facilities with significantly lower safety standards, leading to the contamination of groundwater and a surge in respiratory illnesses in border communities like Tijuana and Ciudad Juárez.

One of the most critical points in the UN findings is the surge in plastic waste exports. Since China and several Southeast Asian nations banned plastic scrap imports in 2018, Mexico has become a primary destination for American plastic “recycling” that is often unrecyclable. “What the US labels as ‘circular economy exports’ are, in reality, mountains of mixed polymers that end up in illegal open-air incinerators,” Orellana stated. “Mexico is being forced to breathe the toxic fumes of American consumption.”

The UN expert also pointed to the “shameful” export of pesticides that are banned for use within the United States due to their link to cancer and reproductive issues, yet are still manufactured and shipped to Mexican agribusinesses. This “double standard” in chemical safety, Orellana argued, creates a cycle of poisoning that affects Mexican farmworkers and ultimately returns to American dinner tables via imported produce.

In response to the report, the Mexican Ministry of the Environment (SEMARNAT) signaled its intent to tighten import controls, though officials privately acknowledge the difficulty of policing the 2,000-mile border. Environmental groups in Mexico have hailed the UN’s intervention as a “long-overdue validation” of their struggle. “For decades, we have been told this was the price of trade,” said Sofía Rubalcava, a spokesperson for the Front for Environmental Justice. “But no trade deal should give one country the right to use another as a landfill.”

The US State Department has not yet issued a formal rebuttal, though a spokesperson noted that the US is “committed to working with our partners to improve waste management infrastructure.” However, the UN report recommends a fundamental shift: the US must ratify the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes, which would legally prohibit the export of many of the materials currently clogging Mexican landscapes.

As the 2026 hurricane season approaches—threatening to wash industrial runoff from these dumping sites into the Gulf of Mexico—the “toxic crisis” is no longer just a local concern. It has become a high-stakes test of whether “North American cooperation” can extend beyond profit margins to protect the shared air and water of a continent.
