Tvind and Humana People to People are alleged to be behind a group of similar organisations that have placed tens of thousands of used clothes collection bins throughout the United States and Western Europe. Advertised as supporting environmental causes, the organizations behind the bins instead sell the clothes and channel the profits to a small circle of Tvind leaders, say investigators. Humana People-to-People's donation bins can be found in many European countries except in Scandinavia, where clothes are collected under the name UFF.
