The clean-up operation begins.

Millions of pellets which are used to make plastic have been washed up on Hong Kong's beaches, following the worst typhoon in 13 years.

Environmentalists are concerned that the pellets will absorb dangerous toxins, which could enter the food chain.

Several hundred volunteers turned up to try and remove the translucent pellets, but the beaches could still take months to clean.
