KUALA LUMPUR — Malaysia’s environment minister Yeo Bee Yin announced on Jan. 20 that her country has returned almost 4,000 tonnes of plastic rubbish to mostly Western countries in recent months. “We do not want to be the garbage bin of the world,” the minister said, warning would-be sending countries to “dream on” if they expect Malaysia to recycle their rubbish for them. The cost of repatriating the rubbish from Malaysia will be borne by sending countries and shippers, Yeo said, echoing her counterparts in the Philippines and Indonesia, countries that have also reacted furiously to the trade in foreign plastic rubbish and sought to make senders pay for shipping their garbage back to where it came from. Since China banned the import of plastic waste for recycling in 2017, Southeast Asia has become a magnet for the largely-illegal trade, while images of fields of plastic rubbish bobbing on turquoise seas and of stinking plastic-engorged landfills have fueled concerns about a worldwide “plastics crisis,” with China, estimated to be the world’s biggest source of plastic pollution, becoming the latest country to ban single-use plastics on Jan. 19. This stern “polluters-will-pay-a-price” message is the subject of a new study by the World Economic Forum and PwC, one of the world’s “Big Four” accounting firms. Not only are polluters likely to see their good names tarnished or face financial sanctions, businesses and governments are shooting themselves in the foot by damaging the environment upon which some commercial activity depends.
