The country has been inundated with shipments of illegal plastic waste since 2018, when China cracked down on a large recycling industry.
On Monday the country's environment minister, Yeo Bee Yin, said she ordered 3,737 metric tons of trash to be returned to 13 countries.
Of the 150 containers, 43 were sent back to France and 42 to the UK, while the US will receive 17 and Canada 11.
The countries from which the waste originated and the shipping companies covered the cost of the returns, she added.
China banned imports of plastic waste two years ago, as part of an initiative to clean up its environment. That move caused a ripple effect through global supply chains, as middlemen sought new destinations for their trash, including Malaysia.
A recent Greenpeace report found that during the first seven months of 2018, plastic waste exported from the US to Malaysia more than doubled compared with the previous year.
In May, the governments of 187 countries, including Malaysia, agreed to add plastic to the Basel Convention, a treaty that regulates the movement of hazardous materials from one country to another, to combat the dangerous effects of plastic pollution worldwide. The US was not among them.
