Transnational organized crime organizations aren’t just trading in things like cocaine and counterfeit Rolexes—some turn to the illicit plastic trade.

According to a recent report by Global Initiative, an organization devoted to identifying and fighting transnational corruption, illicit plastic is making its way from wealthier regions like North America and Europe into less-economically-developed areas such as Southeast Asia and Africa through shady intermediaries.

The study, Plastic for Profit, provides a cursory insight into the underground world of moving plastic around the world that no one wants. The complex nature of international shipping means that there are many ways that criminals can move illicit recycled plastic, from using fraudulent documentation and hiding under layers of legal shell companies to exploiting the lack of resources and education of authorities in developing nations.
