New MIT study reveals how biofilms help stop microplastic build-up
Friday, 13 June 2025 () Where do microplastics really go after entering the environment? MIT researchers discovered that sticky biofilms naturally produced by bacteria play a surprising role in preventing microplastics from accumulating in riverbeds. Instead of trapping the particles, these biofilms actually keep them loose and exposed, making them easier for flowing water to carry away. This insight could help target cleanup efforts more effectively and identify hidden pollution hotspots.
