The 2006 Ivory Coast toxic waste dump was a health crisis in Ivory Coast in which a ship registered in Panama, the Probo Koala, chartered by the Singaporean-based oil and commodity shipping company Trafigura Beheer BV, offloaded toxic waste to an Ivorian waste handling company which disposed of it at the port of Abidjan. The local contractor, a company called Tommy, dumped the waste at 12 sites in and around the city in August 2006. The dumping, which took place against a backdrop of instability in Abidjan as a result of Côte d'Ivoire's first civil war, allegedly led to the death of 17 and the injury of 30,000.
In the days after the dumping, almost 100,000 Ivorians sought medical attention after Prime Minister Charles Konan Banny opened the hospitals and offered free healthcare to the capital's residents.
Trafigura originally planned to dispose of the slops – which resulted from cleaning the vessel and contained 500 tonnes of a mixture of fuel, caustic soda, and hydrogen sulfide – at the port of Amsterdam in the Netherlands. The company refused to pay Dutch company Amsterdam Port Services (APS) for disposal after APS raised its charge from €27 to €1,000 per cubic meter. The Probo Koala was reportedly turned away by several countries before offloading the toxic waste at the Port of Abidjan. An inquiry in the Netherlands in late 2006 confirmed the composition of the waste substance.
Trafigura denied any waste was transported from the Netherlands, saying that the substances contained only tiny amounts of hydrogen sulfide, and that the company did not know the substance was to be disposed of improperly. After two Trafigura officials who traveled to Côte d'Ivoire to offer assistance were arrested and subsequently attacked in jail, the company paid US$198 million for cleanup to the Ivorian government, without admitting wrongdoing in early 2007. A series of protests and resignations of Ivorian government officials followed this deal.
In 2008, a civil lawsuit in London was launched by almost 30,000 Ivorians against Trafigura. In May 2009, Trafigura announced it would sue the BBC for libel after its Newsnight program alleged the company had knowingly sought to cover up its role in the incident. In September 2009 The Guardian obtained and published internal Trafigura emails showing that the traders responsible knew how dangerous the chemicals were. Trafigura agreed to a settlement of £30 million (US$42.4 million) to settle the class action suit against it. Law firm Leigh Day, which represented the Ivorian claimants, was found guilty of negligence after £6 million of the settlement funds were embezzled.
