The Hidden Dangers of Burning Waste: Chemicals and Coal Ash

As the United States looks for ways to manage its waste, a growing conflict has emerged over how to handle toxic materials. Two major areas of concern are the use of garbage incinerators and the storage of coal ash, which is the leftover material from burning coal to create electricity. While industry groups often present these methods as efficient solutions, environmental advocates and independent experts warn that they may be causing serious harm to the public.

One major issue involves PFAS, a group of at least 16,000 chemicals used to make products resistant to water, stains, and grease. These are often called “forever chemicals” because they do not break down naturally in the environment. According to The Guardian, these chemicals have been linked to cancer, birth defects, and kidney disease. Because PFAS are common in household trash, they often end up in incinerators. However, experts say that most incinerators are not designed to destroy these tough chemicals. Instead, the chemicals can be released into the air, potentially poisoning the neighborhoods nearby.

Industry groups have defended the use of incineration. For example, a report from the Minnesota Resources Recovery Association (MRRA) claimed that incinerators in Minnesota could reduce PFAS emissions by 99.6 percent. However, this report has faced strong criticism. The Zero Burn Coalition, an advocacy group, argued that the report uses incomplete data and misleading language. Nazir Khan, a leader at the Minnesota Environmental Justice Table, stated that such reports deceive the public. He noted that the pollution from these facilities often affects poor and marginalized communities the most.

Michael Youhana, an attorney with the non-profit group Earthjustice, said he is not aware of any commercial incinerator that can successfully solve the PFAS problem. While regulators are starting to look at health standards, many activists believe the current rules are too weak. A lawsuit has even been filed against the Environmental Protection Agency (EPA) regarding its emissions standards. Critics argue that the industry is trying to avoid stricter rules by downplaying the risks of inhaling these chemicals.

At the same time, a different battle is taking place over coal ash. This powdery residue contains toxic metals like mercury, arsenic, and lead. According to Ars Technica, more than 90 percent of coal power plants in the U.S. have been found to contaminate groundwater with this ash. While some of this material is used to make concrete or drywall, large amounts remain stored at power plant sites.

Recently, the EPA proposed new rules that would weaken the requirements for cleaning up coal ash. The administration, led by EPA Administrator Lee Zeldin, described these changes as “commonsense” steps to help the energy industry. The new rules would allow states to have more control and might let companies delay or avoid dealing with coal ash at their facilities. The administration argues this approach supports energy independence and helps manage unique situations at different plants.

However, environmental groups strongly oppose these changes. Lisa Evans, a senior counsel at Earthjustice, stated that the new policy puts the nation’s drinking water at risk to help polluters. During a public hearing, many advocates voiced their concerns, arguing that the government should prioritize public health over the needs of the energy industry. They worry that moving away from national standards will make it easier for companies to ignore the dangers of toxic ash.

These two issues share a common theme: the challenge of managing industrial waste in a way that protects human health. As the government considers its next steps, the debate continues between those who want to support industrial energy production and those who demand stricter environmental protections. For now, the future of how the U.S. handles these toxic materials remains uncertain, leaving many communities worried about the air they breathe and the water they drink.
