Malaysia will send back some 3,000 metric tonnes of non-recyclable plastic waste to countries such as the US, UK, Canada and Australia. It comes as a move to avoid becoming a dumping ground for rich nations. Malaysia became the world's main destination for plastic waste after China banned its import last year, disrupting the flow of more than seven million tonnes of trash.
People from the UK to Mexico are posting photos of rubbish they've collected as part of an online challenge.
