New Satellite Technology Detects Plastic Waste on Beaches

Australian researchers have developed a method using satellite imagery to identify plastic debris along coastlines from space.

RMIT University in Australia has created the Beached Plastic Debris Index (BPDI) to detect plastic waste on beaches using satellite imagery.
The technology distinguishes between sand, water, and plastic by analyzing how they reflect light differently, allowing for effective monitoring from over 600 km above Earth.
Field tests showed the BPDI outperformed existing methods in identifying plastic waste, even on remote beaches.
Plastic pollution is a significant environmental issue, with millions of tons entering oceans annually, impacting marine life and ecosystems.
The research team aims to partner with organizations to expand the technology's application globally, aiding in targeted clean-up efforts.
