A new study reveals how a common household chemical, when combined with certain environmental factors, may significantly accelerate the degradation of plastic waste in landfills. Researchers found that exposure to sunlight and moisture can trigger a reaction between the chemical and plastic polymers, breaking them down into smaller, more hazardous microplastics at an alarming rate. The findings challenge previous assumptions about plastic longevity and raise concerns about the long-term environmental impact of landfill waste. Experts warn that this discovery could reshape waste management strategies and recycling efforts worldwide.
