Largest UK study to date uncovers hidden chemical risks in waste-to-energy residues

Energy-from-waste facilities are often positioned as a cleaner alternative to landfill, transforming rubbish into electricity and reducing the UK's waste burden. But new research suggests that there may be a hidden cost to this process: potentially hazardous chemical residues that remain largely out of public view. A study from the University of East London (UEL) has uncovered new evidence about the risks posed by air pollution control residues (APCr)—a fine, highly alkaline powder produced when harmful pollutants are captured from incinerator flue gases.
