Of the seven ‘Müllkoffer’ kits, three are held at the ICBM in Wilhelmshaven, one is on permanent loan to the UNESCO Wadden Sea World Heritage Site Visitor Centre in Wilhelmshaven, two are held by Mellumrat e.V. (in Dangast and on Wangerooge) and one at the Wadden Sea Learning Centre in Oldenburg. The ‘rubbish kits’ are lent out by these institutions to interested teachers and environmental organisations, and are also occasionally used for their own events.
