‘Humble’ worm saliva can break down tough plastic – BBC News

One of the worst forms of plastic pollution may have met its match in the saliva of a humble worm.

Spanish researchers say they’ve discovered chemicals in the wax worm’s drool that break down polyethylene, a tough and durable material.

The researchers say that one hour’s exposure to the saliva degrades the plastic as much as years of weathering.

They hope the breakthrough will lead to new natural approaches to deal with plastic pollution.
