Exclusive: Use of toxic plastic beads in treatment works is unnecessary and outdated say conservationists after hundreds of millions wash up on beach

The use of tiny, toxic plastic beads at sewage works should be banned nationwide, an MP and wildlife experts have said after a devastating spill at an internationally important nature reserve.

Hundreds of millions of “biobeads” washed up on Camber Sands beach in East Sussex last month, after a failure at a Southern Water sewage treatment works caused a catastrophic spill. This caused distress and alarm for local residents and conservationists, as not only are the beads unsightly, but they pose a deadly threat to wildlife.
