The Philippines and Canada are involved in a legal battle over which country is responsible for roughly 2,500 tons of trash that was shipped to Manila in 2013 and 2014 from Canada.

A private business in Canada had shipped 103 containers of trash labeled as mixed plastic recyclables to Manila several years ago. But those containers actually concealed an “unsorted mix of electronic and household waste, including adult diapers,” reported Popular Science.

Now, a 2016 legal ruling could mean Canada would have to reclaim the privately-owned waste.
