 Further prosecutions against Ivorian citizens not employed by Trafigura continued.On 6 December 2006, an independent inquiry launched by the City of Amsterdam concluded that the city was negligent when they allowed Trafigura to take waste back on board the "Probo Koala" in Amsterdam in July.Part of the "Probo" cargo was offloaded with the intent to have it processed with an Amsterdam waste processing company but when this turned out too expensive Trafigura took it back.
