Malaysia will send back almost 3 000 metric tons of non-recyclable plastic waste to countries including the United States, Great Britain, Canada and Australia in a move to avoid becoming a “dumping ground” for rich nations.

Environment Minister Yeo Bee Yin said on Tuesday that 60 containers stacked with contaminated waste were smuggled into illegal processing facilities in Malaysia and will be sent back to their countries of origin.

Ten of the containers will be shipped back within two weeks, Yeo said, as she showed reporters contents of the waste at a port outside the capital, Kuala Lumpur.

The items included cables from the United Kingdom, contaminated milk cartons from Australia and CDs from Bangladesh, as well as bales of electronic and household waste from the US, Canada, Japan, Saudi Arabia and China.

Yeo said Malaysia, and many developing countries, have become new targets after China banned the import of plastic waste last year.

“This is probably just the tip of the iceberg [due] to the banning of plastic waste by China,” Yeo said at a news conference.

“Malaysia will not be a dumping ground to the world, we will fight back. Even though we are a small country, we can’t be bullied by developed countries.”

Last week, the Philippines said it would ship back dozens of containers of garbage which Filipino officials were illegally shipped to the country from Canada in 2013 to 2014.

Yeo said the waste from China appeared to be garbage from France and other countries that had been rerouted after Beijing’s ban.

The government has clamped down on dozens of illegal plastic recycling facilities that had mushroomed across the country, shuttering more than 150 plants since last July.
