Founding Fathers
Jack van Ham
Jack van Ham was in de 1e fase van professionalisering voorzitter van het bestuur: ‘Mede om ervoor te zorgen dat er ook middelen konden worden geworven om nog meer te kunnen betekenen in de strijd tegen wereldwijde plastic vervuiling en het gebruik ervan. Momenteel ben ik gepensioneerd. Eerder was ik CEO van het Nederlandse Rode Kruis en Voorzitter van de Raad van Bestuur van ontwikkelingsorganisatie ICCO.’

Dieter Croese
‘Ik ben dankbaar dat ik vanaf 2014 structuur en financiële rust heb kunnen bieden als penningmeester. Mede door de CBF-accreditatie is de organisatie stevig gegroeid. De missie van Plastic Soup Foundation verdient het deze groei door te zetten, zodat komende generaties kunnen genieten van de natuurlijke pracht van onze planeet.’
Peter Keijzer
‘Massaal en verkeerd gebruik van plastic is één van de bedreigingen van het welzijn op aarde. Gelukkig had Maria Westerbos dat al vroeg door. Met veel plezier kon ik haar en de PSF helpen om daar structureel iets aan te doen. Veel bereikt, geleerd en eeuwig dankbaar.’
