Study: Biodegradable Products May Be Bad For The Environment
Research from North Carolina State University shows that so-called biodegradable products are likely doing more harm than good in landfills, because they are releasing a powerful greenhouse gas as they break down.
“Biodegradable materials, such as disposable cups and utensils, are broken down in landfills by microorganisms that then produce methane,” says Dr. Morton Barlaz, co-author of a paper describing the research and professor and head of NC State’s Department of Civil, Construction, and Environmental Engineering. “Methane can be a valuable energy source when captured, but is a potent greenhouse gas when released into the atmosphere.”
