Pieter Pot, you say? What’s that? A “pot” is dutch for a jar and that’s the core business of Pieter Pot, an online supermarket that delivers packaging-free groceries in reusable glass jars and bottles. Pieter Pot is a start-up from the Netherlands who made their first delivery in Belgium last October. Since then more than 8000 customers in Belgium are ordering their groceries in a “pot”.
